I become obsessed with things. Sometimes it can be a particular food or an album (this Jimi Hendrix "vault cleaning" as Rolling Stone describes currently has my ear). Other times, as my mind is often tuned to baseball topics, I incessantly think about a concept from the diamond or evolution of a new statistic. Pitch tunneling is the recent topic that has earned a spot in my head.
This isn't the first time I've gravitated towards pitch tunneling. Last year I wrote a column about Dylan Bundy's cutter-slider, it's usage, and why that pitch is one reason I irrationally like the volatile arm. As I've rekindled my interest in the concept, now was the time to refresh myself after Baseball Prospectus' recent update. Contextualizing arms by combining what we know and what we can learn from tunneling can provide a reasons for optimism.
I'll admit, this post might get a little bit convoluted, so if you're not in the mood to try and understand pitch tunneling and determine how much you value it, feel free to hop to one of my last three Razz articles, there's something for everybody (On Scott Kingery; On ADP discrepancy; On Michael Wacha). Or just skip down to the heading for Patrick Corbin. I'll try my best to keep things as simple and concise as possible. Trying to teach a concept is often a great form of learning, so I'll admit writing this post, in a way, helps me to try and understand it better.
Stephen Piscotty Batting Order Game Averages | Current Season
Stephen Piscotty current season averages per batting order spot along with 12 team mixed fantasy value ($). Only includes games started. Games started percentages for RHP vs LHP are based on last 30 days.
Stephen Piscotty projected to 150 Games vs RHP and LHP with 12 team mixed fantasy value. This helps identify a player's platoon value for fantasy baseball based on pitcher handedness. These projections by Steamer are a MUCH better indicator of a hitter's platoon splits than in-season stats since it involves multiple years of data and has been properly regressed to league averages. Since games are neutralized across players, values for everyday players may look smaller than for preseason/season to date/rest of season where they benefit from playing time advantages vs other players. In general, left-handed hitters have larger platoon splits.
Our Steamer hitter projections are based on Steamer rate stats vs RHP/LHP and we adjust based on our projected playing time and RHP/LHP Plate Appearance split. Grey projects his stats as part of his 2016 Fantasy Baseball Rankings. Both $ estimates are based on 12 team 5x5 mixed leagues with a 67/33 hitter/pitcher split. Prospectonator reflects 150 game projections for hitters with no more than 130 career plate appeareances.
