MLB picks today center on three American League races with plenty still at stake Wednesday. Cleveland is trying to protect its AL Central lead in Boston, Tampa Bay and New York could still have business to settle in the East, and Houston heads to Seattle trying to stay within reach of Texas out west.
New users who sign up with Kalshi promo code ACTION55 can trade $25 and get $55 in bonus trading credit. Wednesday's MLB slate gives you several prediction markets to consider before first pitch.

Best MLB Picks Today: Wednesday, September 23, 2026
| Game | Prediction |
|---|---|
| Guardians vs. Red Sox | Red Sox to win |
| Rays vs. Yankees | Yankees to win |
| Astros vs. Mariners | Mariners to win |
Red Sox to Beat Guardians
MLB Pick: Red Sox to win
Gray is the main reason to prefer Boston in the opener. He enters with a 2.82 ERA compared to Griffin's 3.67, and the Red Sox get the matchup at Fenway.
Cleveland has far more riding on the result, but that doesn't automatically create an edge on the field. Boston's starting-pitching advantage is enough for me to prefer the Red Sox contract if the live price remains reasonable.
Yankees to Beat Rays
MLB Pick: Yankees to win
Cole gives New York the pitching angle I want in this matchup. Tampa Bay could also enter Wednesday with the AL East already clinched depending on Tuesday's results.
Check the standings before trading this market. Either way, I'm siding with Cole and the Yankees at home rather than relying on Tampa Bay to carry its division momentum into another game in the Bronx.
Mariners to Beat Astros
MLB Pick: Mariners to win
Seattle is my preferred side in the late game. Kirby enters with a 3.60 ERA compared to Kikuchi's 4.19, while Houston has dropped seven of its last ten during a costly September slide.
The Astros still have the AL West race to play for, but Seattle has the starting-pitching edge I prefer for Wednesday's matchup.

Guardians @ Red Sox
Cleveland enters Wednesday at 81-75 with a one-game AL Central lead over Chicago. Foster Griffin brings a 3.67 ERA into Fenway against Sonny Gray at 2.82, giving Boston the stronger starting-pitching numbers while the Guardians try to protect their division cushion.
Rays @ Yankees
The AL East could already be settled by first pitch after Tampa Bay entered Tuesday's doubleheader with a six-game lead and a magic number of one. Gerrit Cole gets the ball for New York on Wednesday, making the Yankees one of the first teams to check across different prediction market apps.
Astros @ Mariners
Houston has lost seven of its last ten and enters Wednesday one game behind Texas in the AL West. George Kirby (13-11, 3.60 ERA) starts for Seattle against Yusei Kikuchi (9-9, 4.19 ERA), giving the Mariners the better starting-pitching profile on paper.
How Kalshi Contracts Work
Kalshi contracts trade between 1 cent and 99 cents and settle at $1 if the selected outcome occurs or $0 if it doesn't. A contract trading at 60 cents costs $60 for 100 contracts and returns $100 if it settles as a winner.
Prices can change as traders buy and sell contracts, so check the live market rather than relying on an earlier snapshot.
Readers who prefer conventional sports betting can use MLB betting promos as an alternative to prediction market contracts.
