Yankees vs. Orioles Odds, Preview, and Expert Pick on Kalshi
Prediction markets appear split on where this outcome lands, with both sides hovering around the 50% mark.
Will Warren (8-6, 4.42 ERA) gets the ball for the Yankees, and he'll look to get back on track after allowing three long balls at home against the Mariners. The right-hander has dominated the Orioles this season, going 2-0 with a 2.25 ERA, and punching out 15 batters over 12 innings of work. If there's one bat in Baltimore's lineup to pitch carefully around, it's Cole Cowser, who is 3-for-9 with three doubles against Warren in his career.
Speaking of those O's, Chris Bassitt (4-4, 5.11 ERA) will look to keep his team in the thick of the AL Wild Card hunt with a strong outing tonight. Bassitt's last outing was his first in over two months, and he looked solid, allowing only two runs over 5 1/3 innings. Although he has yet to face the Yanks this season, Bassitt has found plenty of success in one particular setting: pitching at home. In the confines of Camden Yards, Bassitt has posted a 3-1 record and 3.09 ERA in six starts, while going 1-3 with a 7.28 ERA in seven road starts. Trent Grisham is definitely someone Bassitt will be pitching tightly, considering Grisham has taken him yard twice in his career – and he's got three homers over the last six games.
- Yankees vs. Orioles Prediction: Orioles to win (46%): Aaron Judge (the most notorious Oriole killer of all time) ain't walking out of that dugout! The Bronx "Bombers" recently went through a stretch of scoring one run or fewer in three straight games, and it appears like the glimmer on those trade deadline moves is starting to fade a bit. I like how the Orioles have been playing recently, even scratching and clawing in losing efforts. Bassitt has been remarkable at home, and Warren has struggled throughout his career against lefty bats – which the O's have plenty of. Baltimore is typically Yankee Stadium South, but it's the middle of the week, and Birdland has postseason aspirations here in 2026.
