Drew Rasmussen Under 5.5 Strikeouts: MLB AI Pick for September 22, 2026
Rithmm is an AI sports betting research platform that helps everyday bettors read full MLB slates with transparent model projections before they wager. The models surface win probability, Edge, and form across the last 5, 10, and 20 games so you can compare price to projection instead of guessing from a highlight clip.
On every prop you get the models, Edge, line shopping across DraftKings, FanDuel, BetMGM, Caesars, BetRivers, Hard Rock, Kalshi, Polymarket, Novig, and more, plus Scout, Rithmm’s AI sports betting analyst on Pro and Premium. Rithmm is available on web, iOS, and Android, with a 7-day free trial (credit card required). Choose Pro or Premium if you want to test Scout.
Edge is the gap between the models’ win chance and the sportsbook-implied price. Win probability is shown against the book-implied number so you can see whether the line still makes sense. Recommended and cautioned props stay on the same board with reasons attached, so you see the full slate rather than a shortlist of hype plays.
Tonight’s featured AI sports picks read is a pitcher strikeout under that three separate historical buckets keep lighting up on the same side of the line.
Drew Rasmussen Under 5.5 Strikeouts vs the Yankees
Tampa Bay right-hander Drew Rasmussen starts at Yankee Stadium tonight against New York. First pitch is listed at 6:05 PM on the card. The prop is Under 5.5 Pitcher Strikeouts at −130. The Rithmm prop models project 5.0 strikeouts, put a 57.2% win chance on the under, and show +1.5% Edge. The Bet Info bar reads Under 57% against Over 43%, the card is marked recommended, and the score sits at 5/10. Rasmussen has gone under 5.5 pitcher strikeouts in 5 of his last 10 games.
Public context around the start is strong. Rasmussen enters the night around 15-5 with a 2.72 ERA and a heavy workload north of 160 innings, lined up opposite Max Fried in a late-September Yankee Stadium series. A quality starter on a juiced under at −130 can still be a value spot when the projection sits half a strikeout under the number and the historical under buckets keep cashing in the same win-chance band.
What the models keep seeing on strikeout unders
When starting pitchers land in the mid-to-high 50s win-chance band on strikeout unders, the historical sample has been sharp. One starting-pitcher under bucket in that 57-60% band is 43-20 across 63 bets, a 68.3% win rate and +19.2% ROI, and the recent half of that sample is running even hotter at 9-2. The broader pitcher strikeout under bucket in the same probability band is 47-23 across 70 bets (67.1% win rate, +17.1% ROI), with a recent 12-2 stretch. Tightening further to the same band with modest expected value still holds 42-20 across 62 bets (67.7% win rate, +17.3% ROI), also heating on a 12-2 recent run.
Three overlapping under signals all pointing at the same prop type is the story. Rasmussen’s card sits right in that 57% win-chance pocket, the models are a half-K under the posted 5.5, and the price at −130 still leaves a small positive Edge on the app card. That is the full read: projection under the number, win chance in a historically strong under band, and Edge that clears the juice.
How to use this pick in Rithmm
Open Rasmussen’s strikeout prop and stay on Bet Info first. Confirm the 5.0 projection, the 57.2% win chance, the +1.5% Edge, and the under bar versus the −130 price. Check hit rate across the last 5, 10, and 20 games rather than a single hot stretch, then use line shopping to compare DraftKings, FanDuel, BetMGM, Caesars, BetRivers, Hard Rock, Kalshi, Polymarket, Novig, and more before you lock a number. If you want the plain-English walkthrough of why the under is preferred here, ask Scout on Pro or Premium.
This is one recommended prop on a full board. Rithmm still shows cautioned plays with reasons, so you can fade or pass with the same data stack instead of only seeing the green-star side of the slate.
Final card: Rasmussen Under 5.5 Strikeouts
