Razzball Streamonator – Streaming Pitcher Daily Projections

Updated: | Maintained by

Streamonator is the ultimate streaming pitcher tool. It has the next 7-10 days’ worth of starts with projections and dollar values. For more information, see the Streamonator FAQ or our Subscriptions page. Monthly subscriptions start at just $4.99/month and daily passes as low as $0.99/day.

FAQ: Click here. 


Razzball Streamonator (aka Stream-o-Nator, Stream-o-nater, Streamonater):  This tool is designed to identify attractive short-term pitcher pickups – aka fantasy baseball streamers/streaming pitchers.  It could also be used to determine when to start/sit a pitcher on your roster.  (For Daily Fantasy Baseball games, check out DFSBot). The higher the $ value, the more attractive the start.  Stream-o-Nator MLB pitcher projections rely on Steamer Rest of Season projections as a foundation and then adjust based on several game-specific factors that include opponent strength vs. the pitcher’s handedness, whether the start is home or away and park factors.  Streaming pitchers has inherent risk to it – this tool merely tries to increase the odds for picking a particular start.

What Is The Expected Accuracy Of Streamonator Projections?:  Please see the Razzball Ombotsman for correlations between the Streamonator projections and actual stats.

Filtering Results:  You can filter multiple fields at the same time.  The text fields below the column headers enable several methods for filtering the data.  Here are some examples:

Function Symbol Example Explanation
ANY MATCH ‘NY’ in Opponent field This would filter the results to only pitchers facing the New York Yankees (NYA) and New York Mets (NYN)
OR | David Price|Justin Verlander in ‘Name’ This would display the stats only for David Price and Justin Verlander.
NOT ! !at in Opponent This would remove all away starts (an away game for Atlanta written as ‘at ATL’)
NOR ! | !David Price|Justin Verlander in ‘Name’ This would display the stats for all pitchers EXCEPT David Price and Justin Verlander
GREATER THAN > >10 in $ This would only display rows for pitchers whose projected $ is greater than 10.
LESS THAN < <10 in $ This would only display rows for pitchers whose projected $ is less than 10.
GREATER THAN OR EQUAL TO >= >=10 in $ This would only display rows for pitchers whose projected $ is greater than or equal to 10.
LESS THAN OR EQUAL TO <= <=10 in $ This would only display rows for pitchers whose projected $ is less than or equal to 10.

Position Eligibility – 20 Games in last season for ESPN and ’2 Catcher’ formats.   5 Games for Yahoo.

Pitchers Included: All probable pitchers for up to the next 7 days.  Pitchers with two starts are listed twice.

$ Values – A pitcher’s projected stats for their start are multiplied by 30 then valued for a 12-team MLB league using the ESPN/CBSSports roster format (13 hitters, 9 pitchers) and a $260 team budget.  While the $ values would vary for any other league format, we would expect the rankings to remain relatively the same.  For 12-team leagues, $4 is about the ‘average’ start.  Anything above $0 is ‘better than nothing’ but may be suboptimal in leagues with IP or GS limits. Please see FAQ for $ targets for other league formats.

1-start vs. 2-start calculator – 

The below chart equates the average $ value of a 2-start pitcher’s two starts to a one-start pitcher’s start for weekly leagues.  So if a 2-start pitcher averages $4 in value across his two starts, that is the equivalent of a single start that is worth $7.  This is based on standard 5×5.

Two Start $ Avg Equivalent $ Value of One Start
1 0.5
2 2.6
3 4.7
4 6.9
5 9.0
6 11.1
7 13.2
8 15.4
9 17.5
10 19.6

Own% –  Based on ownership within the Razzball Commenter Leagues which consists of 84 12-team MLB leagues using the standard ESPN roster format.

    simply fred says:

    Hi, Rudy! Hey, looks like you have Bauer slated to start on 4/8….moved to pen?

    • will get to it soon – once i figure out the hitter projections.

  2. Simply Fred

    simply fred says:

    mlb has K.Hendricks starting Sat. Streamonator has him skipped and Arrieta going Sat. Which more likely?

    • @simply fred: more likely Hendricks starts. at this point, i’ve only got probable pitchers for 4-5 days from my feed provider and then my algorithm is filling in the rest. i get an updated file tomorrow or monday that should clarify end of week starters.

  3. Simply Fred

    simply fred says:

    thanks! not a big deal. just trying to respond to your request to help fill in oddities. (see you outed Bauer… :-)

  4. Simply Fred

    simply fred says:

    feed hopefully will solidify after games get rolling. it lists Fernandez starting on 4/6 and then again on 4/10…don’t think that will happen.

    • It will. This first week or two are tough on a # of fronts. Once season gets running, things get a little easier.

  5. Lipson says:

    Hey Rudy, more of a housekeeping request.. any way we can delete call comments from 2015? Also, possible to do a monthly purge to keep the page length short?

  6. A Wesley Snipes Life says:

    subscribed with $10 in fanduel, i’m guessing i’m in the waiting period (says up to 48 hours) till i can use the bots right?

  7. scott says:

    rudy is teamonator working? is it included in the $20 sub? keeps asking me to subscribe. I have the roto subscription.

    • Hi. Teamonator is only available in the DFS packages.

      • scott says:

        @Rudy Gamble:

        damn. ok. any way to get it as a partial add on to the roto? im in ny so dfs does nothing for me

        • @scott: sorry. I don’t have the flexibility to offer it like that. you can access via day pass but it ain’t cheap ($3/day).

  8. El Gato Grande says:

    Seems to have some pitchers missing this morning: Happ, Rich Hill, Latos to name a few. My league allows waiver claims on Sundays and Wednesdays so trying to figure out my streamers for the week. Thanks Rudy.

  9. David Kohn says:

    Hey Rudy,

    Do you know if Conley is pitching against the Mets 4/13 or Atlanta 4/15?

    Yahoo and the streamonator have 4/15, and ESPN has 4/13.

    • you are right. was announced recently that Conley is switching to 4/13 to give Chen more time (who’s pushed to 4/15). all projections have been adjusted.

  10. Chris says:

    Hi, sorry for the dumb question.
    But how do I access streamonator? I just signed up and deposited in FanDuel via your link.

    Can’t seem to see a login/signup option on this website?

  11. Steve says:

    In a 12-team mixed roto league (K/WHIP/ERA/QS/SVHD) that has a 200GS limit, what would be the rough “cutoff” in $ value for a stream? I’m thinking $12 from my experience last year in a 10 teamer (same rules). The FAQ says $4 but I think that isn’t taking into account a GS limit, or may be old.

    • I usually project for something like 180 GS or 1,400 IP/team. I don’t think 200 GS will change it fundamentally. My guess is still around $4 but experience is the best guide. If you’re consistently finding free agents at $10+, go with it. Real hard to come up w/ a universal rule.

      • Steve says:

        @Rudy Gamble:

        Ah, well, if you’re factoring in 180GS then I should be in the clear on that. Do you weight QS and W/L the same towards $value, or does Streamonater favor one over the other?

        • The $ factors Wins, ERA, WHIP, and K’s. It does not factor in QS.

          • Steve says:

            @Rudy Gamble:

            Ah, that may be where the difference in what I look for and what the FAQ suggests comes into play. Good to know! I normally end up looking for something like .60 QS and a relatively high $ value (which is where my $12 value came from last year). Any chance of the Ombotsman tracking QS correlations? I figure it’s safe to assume that a higher $value == more probability at a QS, but the pitchers who have something crazy like a .70+ QS and a sub <$5 value always throw me off.

            (BTW: Thanks for answering, ya'll are the best)

            • Thx. Great request – don’t know why I never thought of it. It’s in there now back-projected through opening day. It’s surprisingly low compared to Wins right now but I think the two will converge. The oddest quirk has been IP/GS has been real low to start the year (5.5 vs my projected 5.9). That’s led to an average QS/GS of 0.43 which is way lower than my projected 0.58. Last year, the QS/GS league-wide was .5 but it’s .54 if you qualify 100+ IP, .56 if you qualify 140+ IP, and .59 if you qualify 160+ IP. Given there are so few ‘replacement’ SPs throwing right now, my average seems more in line with expectations. I think the ‘wrinkle’ is I probably should be discounting IP during the first two weeks of the year.

              • Steve says:

                @Rudy Gamble:

                SWEET. I agree with your “wrinkle”, April is such a crapshoot even without the postponed games and off days. I wouldn’t be surprised if the 7 postponements and the off days to start are affecting the stats (no idea on how many of those postponed were made up). Checking the 2015 stats, it seems like the correlations for other stats are either similar or higher compared to May of last year (no April?), and the projections improve through the year – so this a great starting point for now. I think I can assume that the correlation is more towards your projections for the “known” commodities, until the IPs start to become as expected, and roll with that.


                • I made a huge enhancement in late April last year so decided just to show May-September in the Ombotsman. Made gradual improvements throughout year which are helping now in comparison to May of last year.

  12. MarkDeezNutz says:

    Stream-o-nator likes Pineda today vs. TOR more than Rondon vs. MIN? Do we trust it? I was leaning towards Rondon today

    • Rodon is probably a little ‘safer’. SON likes Pineda’s K potential.

      • MarkDeezNutz says:

        Going with Rodon. He’ll rack up plenty of Ks against Buxton, Park, etc. I’m just a little surprised with the $ value difference. I would have Rodon in the top 5 for the day like the boys over at ESPN. Do you like Pineda over Taijuan Walker today?

        • I’m not buying in on Rodon until he proves he has improved his control. Solid first start. Before you bury the Twins, worth noting their better bats are RH and they’ve only faced one LHP all year (Quintana who has reverse splits). Won’t be K’ing at same rate.

          I prefer Walker over Pineda today. I think Walker is a definite 12-team start, Pineda is a marginal start that I would bench b/c of the downside, and I wouldn’t start Rodon either.

          • MarkDeezNutz says:

            very interesting…

          • Ben says:

            @Rudy Gamble:

            Did you watch his last start? Got squeezed on a couple would be strike 3s that led to walks. Could have easily been 8 or 9 Ks vs 2 or 3 walks. I would not use that last ump’s strike zone as an indication of where he is in terms of his control.

            • @Ben: Rodon had 4.59 BB/9 last year. I’m basing my opinion off that.

  13. Steve says:

    Hey Rudy,

    If we’ve subscribed to the site, is there any way to get rid of the ads?


    • @Steve: No, but we took the expanding ads off the subscription pages.

  14. Brett Moore says:


    On one of my computers SON works just fine. However on the main computer I use when I sign in I get the “thanks for subscribing, just a minute” message & then the whole Razzball screen goes white. nothing happens after. do you know what the issue might be? thanks

    – Brett

    • @Brett Moore: Hey Brett – What browser are you using on the computer in which it doesn’t work? Have you tried another browser on that same computer?

  15. Ed says:

    Is there any way to see changes in price from day to day?

    I could have sworn Bartolo Colon was a ~$7 value for todays (4/20/16) start against the Phils up until this morning.

    My first year using this software, is it generally a bad idea to jump on a good stream a few days early?

    Thanks Rudy.

    • @Ed: I archive pitcher projections but overwrite them each morning. The only projections that are saved are the ‘final’ ones which I include in my Ombotsman testing. His $ today is $4.7 so that’s not terribly off from where he was a few days ago. The day-to-day changes come from the following:

      1) Active hitter roster changes – So if, say, Franco went on the DL, Colon’s $ would likely increase as his projected stats would be better. If the pitcher’s offense gets better/worse based on roster changes, this has a slight impact on Win projection. This changes day-to-day.

      2) Today’s Weather – I incorporate weather starting with the ‘morning run’ of today’s projections. Took a look and the wind is blowing out slightly in Philly today (3-4 MPH to CF). So that might have goosed up his ERA/WHIP a bit.

      3) Today’s Lineup – Once that’s posted, this will have an impact similar to #1. It generally shouldn’t hurt pitchers too much since the ‘best’ hitters are generally projected to play. PHI/NYN lineups haven’t posted so not a factor.

      I think you’re doing the right thing in using the Streamonator to identify upcoming attractive starts. But the $ estimates are going to evolve based on the above and you should always take a glance on the day of the game (particularly after lineups post) to make sure it’s still an attractive start.

      Let me know if you have any questions.


      • Ed says:

        @Rudy Gamble:

        Thanks for the quick and informative reply. I’ll keep these factors in mind in the future.

        I have found both of your streaming tools to be effective for me already this year. I’m sure they’ll get more accurate as the season progresses as well.

        I think you’re selling this information too cheap, but I guess the market dictates the price.

        • Thx Ed. We could price it higher but we don’t want to price out fantasy baseball fans who don’t play in cash leagues.

  16. Brett Moore says:


    the computer that has the issue uses Windows 10 & the newer Microsoft browser (I think its called microsoft edge. I’m in no way a tech guy).

    the one that works fine uses an older version of windows and internet explorer

    – Brett

    • edge has been an issue for sure. Cointent still working on compatibility with it.

  17. Jake says:

    HI Rudy,

    Sorry to bother you but the daily pitcher streamonator has some funny things going on. Eickhoff is schedule against Carracso on 4/30, but Carrasco doesn’t show up as a starter on 4/30.

    Same things was happening with Samardzija yesterday, but now seems fixed.


    • @Jake: Hmm, weird. Digging into it this morning. Thanks for reporting it!

    • @Jake: fixed. was related to my recent inclusion of lineup links in the Streamonator. dumb code mistake.

  18. John says:

    Download to CSV! I love you, Rudy. Is there anywhere on the site with an update on how well these tools are doing? I’ve missed out on some points choosing one guy over the other based on dollar values (In a few instances now where both players were expected to have good days) and I’m wondering if it was just luck or if there’s something I could have taken into account that I didn’t. I’m in a linear weighted stats league and minutiae counts (woba and whip being my main guidelines)

  19. gobiggreen says:

    The Date Field won’t update. You can sort by the column but can’t search for a date.

    • @gobiggreen: We made an update to the filtering yesterday. You need to clear your browser history + cookies/plugins. Let me know if that doesn’t do the trick.

  20. Davis says:

    I’ve cleared my browser history and cookies, but using the pipe for “and” isn’t working. I’ll get it to show me one guy but as soon as I add the pipe it all disappears and never comes back.

  21. Jesse says:

    Jonathan Gray’s projection today (5/2) seems off. His projected ERA and WHIP (2.80 and 1.14, respectively) are lower than I would think, but hey it’s the Padres in SD. But what seems really off is the win probability of 0.4 vs a loss probability of 0.26. The Rockies are only slight favorites in this game (-112), going up against Shields who is decent. According to these projections, I should go put some big dollars on the Rockies.

    • i did a double take on that one too. it’s hard to judge rockies based on their yearly projections b/c of the home park disadvantage. i didn’t bid on him in weekly FAAB leagues b/c i don’t trust any rockie pitcher right now for home starts. not going to stream him in daily change leagues but not totally opposed to it. i’m quite surprised to see that Teamonator (razzball.com/teamonator) calls the Rockies 58/42 favorites (-140).

      Gut says SON is a little bullish.

      • Jesse says:

        Gray proved me wrong.

  22. Jedimasters says:

    Hey Rudy. I’m a huge fan of SON and have been using it the last three years. If I can make a couple of recommendations. Perhaps you can remove the HBP column and insert a column showing a trend on how hot or cold the opposing team has been. For example, the Padres from 4/27, 4/29 and 4/30 scored 9, 5 and 5. That’s relevant to show that a team is going through a mini hot streak.

    • Thanks for using SON!

      I looked into recent game last year at the individual hitter and pitcher level and found bupkis for its ability to help project today’s games (under ‘pitcher streakiness’ and ‘hitter streakiness). So that would likely also go for team offense. So many noise factors come in like quality of starting pitcher, park factors, home/away, weather, etc.

      It’s not that I totally discount the “gang up on the cold team” but I prefer not to add things to SON which might lead to less optimal decisions.
