Two matchups featured on the August 20 slate offer a broad range of player markets. Perhaps your picks will come from the Yankees-Orioles series finale. If so, note the following:
The Yankees are handing the ball to Gerrit Cole, who has been highly effective across his 86.2 innings of work. The veteran ace sports an impressive 3.22 ERA and a stifling 1.09 WHIP, while continuing to miss plenty of bats with 9.55 strikeouts per nine innings.
In contrast, the Orioles turn to Kyle Bradish. While the right-hander has provided valuable length for Baltimore this season (133.0 IP), his peripheral numbers suggest he could struggle against New York’s offense, even considering their injuries. Bradish enters the matchup with a 3.65 ERA and an elevated 1.36 WHIP, largely driven by a concerning walk rate of 3.92 free passes per nine innings.
Sportsbook props and Underdog projections are not interchangeable. A sportsbook may offer an over/under with odds attached, while Underdog generally asks users to select whether a player will finish higher or lower than a posted projection. Lines can also differ across operators and change as lineups, weather, and pitching plans are confirmed.
