1. LHP Thomas White | 21 | AAA | 2026

At 6’5” 210 lbs., White wields the kind of stuff that would work against anybody: a mid-90’s fastball, a picturesque curve and disappearing changeup. It’s especially perilous for left-handed hitters, and as Blake Snell has proven, if you can eliminate lefties, you’re way ahead before the game begins. He dominated High-A and Double-A, and while he’s lost the strike zone a bit through two Triple-A starts, he still has 17 strikeouts in 9.1 innings against much older players. Miami is back in a familiar spot for the franchise, looking forward to the development of an extremely promising pitching staff while fielding a lineup peppered with question marks.

1. LHP Cam Caminiti | 19 | A | 2027 

The 24th overall pick in the 2024 draft, Caminiti dominated Low-A this year with premium velocity at 6’2” 195 lbs. I bumped his timeline up a year from last year’s Atlanta list because this org tends to slam the gas when they deem a guy ready to contribute. He’s allowed just one home run in 56.1 Low-A innings across 13 starts, recording a 2.08 ERA, 1.22 WHIP and 75 strikeouts against 28 walks. Easy to root for this guy.

Here’s a link to the Top 50 Update For Mid-September 2025 

51. Twins SS Kaelen Culpepper | 23 | AA | 2026

52. Red Sox LHP Connelly Early | 23 | MLB | 2025

Early looks great in the nascent stages of his Boston tenure, and Culpepper looks like the six of the near future in Minneapolis. Proximity matters a lot to me in dynasty leagues.

1. Brewers SS Jesus Made | 18 | AA | 2026

2. Pirates SS Konnor Griffin | 19 | AA | 2026

My guess is that every single other list will have Konnor Griffin at the top, and that’s totally understandable. I’ve said before that he’s a pull-heavy hitter headed to a poor park for that skill set in a poor organization when it comes to helping hitters reach their potential. Love the player. Love Made just a little bit more, given all the variables.

Red Sox LHP Connelly Early recorded a 2.60 ERA and 1.11 WHIP in 100.1 innings pitched across two levels of minor league play this year to earn his Tuesday night debut. His 31.9 percent strikeout rate and 22.2 strikeout-minus-walk rates were right in line with career norms for the 2023 fifth round pick out of Virginia. His debut was a thing of beauty: five shutout innings with 11 strikeouts. He’s probably not that good, but Boston has been on fire for a while now when it comes to player development, and I’m in no hurry to bet against them.

The Mets are set to recall RHP Brandon Sproat for his big league debut today. He had a rough start to his season in Triple-A but found his rhythm eventually. His season-long line still includes a 4.24 ERA and 1.24 WHIP through 25 starts, and he’s turned in a couple stinkers among his last four outings, but he had a dominant stretch from June 26 through August 7th, going 4-and-0 with a 2.49 ERA and 1.04 WHIP through 43.1 innings across nine starts. The Mets are a top-five organization when it comes to pitching, so I’d be betting we see more of good Sproat than struggling Sproat in his spot starts from here forward.

With the rosters expanding from 26 to 28, we’ve seen a pile of promotions this week. A lot of them are depth pieces, but we saw some blue chippers, too. 

Freshly promoted Mariners C Harry Ford should get some run behind the plate and cover a few starts in the outfield. Cal Raleigh has tailed off a bit after the All-Star break and would likely benefit from a few more days at DH. In 97 games at Triple-A this year, Ford is slashing .283/.408/.460 with 16 home runs and seven stolen bases.

Phillies OF Justin Crawford (21, AAA) has three home runs and three stolen bases over his last five games. His season-long line is .333/.409/.454 with seven home runs and 43 stolen bases in 54 attempts. Still seems underrated to me in a general kind of way across the lists, and Philadelphia’s front office is complicit in that. Nick Castellanos is under contract for $20 million in 2026, but he comes off the books after that and has been mostly awful this season, posting a negative WAR (-0.7) and .294 on base percentage in 128 games. The team’s best roster for 2026 would probably have a cheap Crawford in left field and Castellanos on someone else’s payroll. Heck that might be true for this year. I realize things are pretty good on the big league side in Philadelphia, but leaving Crawford out of his post-season push feels like a mistake to me.

Rays LHP Ian Seymour made his first career start Monday after spending about six weeks in the bullpen. He allowed just two baserunners through five shutout innings, bringing his season-long ERA down to 3.18 with a 1.02 WHIP. At 26 years old with good command of a change-up first arsenal, he’s got a great shot to lock down a rotation spot for the stretch run, and because he’s under a rookie contract, he could look ideal to this front office as a cheap rotation piece for 2026 and beyond. He also gives this team multiple Seymours. Good vision incoming.

Graduated from Prospect News Stash List #9: Wake Up With Snelling Salts: Samuel Basallo, Dylan Beavers, Jhostynxon Garcia, Bubba Chandler, Nolan McLean 

Note: Anyone promoted during the current season is ineligible for the stash list.

 

1. Cardinals SS JJ Wetherholt (22, AAA) 

St. Louis has struggled to sort its pieces for about a decade, so it’s no surprise we haven’t seen Wetherholt in the majors despite him lighting the Triple-A level on fire for a month, slashing .301/.391/.628 with nine home runs and five stolen bases in 29 games. He’s my pick for 2026 National League Rookie of the Year, and I think he’ll open the season with the big league club, but it’s always a little scary waiting on a young Cardinal to get his chance to take flight.

These days are reserved for the true cheapskates. If a minor leaguer is good enough to stress the pricing mechanisms in place to suppress his salary, the cheapskate team is obligated to keep him on a minor league contract as long as embarrassingly possible. How can you not be romantic about Baltimore promoting Dylan Beavers and Samuel Basallo on back-to-back days just after crossing the invisible barrier between trying to win games and trying to spend as little as possible for as long as possible. Or perhaps it was pure coincidence that they were both ready for the next challenge on the same weekend just in time to preserve their rookie status for 2026. It could happen.

The Cubs recalled OF Owen Caissie this week to help spell OF Kyle Tucker, who has been mired in a deep slump for a month. Since July 3rd, he’s slashing .186/.331/.239 over 33 games. There’s nowhere for Caissie to play in an everyday way, so this promotion feels a little strange even as Caissie has certainly earned it, cutting his strikeouts over the last few months, slashing .326/.420/.628 with 16 home runs in his last 59 games. All the Cubs fans I know are pretty doom and gloom about this season now that the team is nine games behind Milwaukee in the National League Central, but the Cubs are still in the thick of the Wild Card race. Perhaps Caissie can bring some hope with him whenever he steps up to bat.
