Why Colton Cowser Under 0.5 Runs Scored vs Zack Littell?
PropsBot’s AI models flagged this at 75.4% Confidence Score on Cowser not crossing home plate against Zack Littell. High Confidence territory. The Edge Score reads 3.1% with a Conf Gap of +8.7% — the model has the Under at ~75% versus the market’s 67% implied. Sharp gap on a fair-juice number.
Historical Performance at 0.5 Runs Scored
Cowser has been shut out frequently. Last 5 games: not a single run scored. L10 Under 90%. L20 Under 85%. Season Under 78%, H2H vs Washington 100%. Every window agrees, and the H2H is the cherry on top.
Matchup Context: BAL @ WAS
Orioles on the road, -1.5 favorites. BAL implied team total 5.1. Game O/U 9.0. Cowser’s underlying is cold: OBP .264, SLG .197, R/G 0.23, Team OPS .724. Sprint speed 28.1 ft/s is solid but reaching base has been the problem. Littell’s Opp WHIP at 1.60 lets baserunners on, but Cowser has to get there himself first, and the OBP and OPS-vs-RHP numbers say he won’t.
Best Line Available
Dabble DFS -137 is the top Under price. Implied 67%. Model says 75%. The 8-point Conf Gap is the play. BetMGM and DraftKings typically post wider Unders on Cowser; shop if you have access.
