White Sox vs Mariners MLB Betting Preview
Two pretty interesting pitchers are going in this one. The giant Noah Schultz heads to Seattle to face Bryan Woo. Schultz hasn't had the best time in the majors so far, posting a 4.91 ERA and a 1.36 WHIP. His problem has been walks.
He's issued 21 free passes in 29.1 innings. He doesn't have a single pitch with a ball rate below the league average. It looks pretty disastrous for him from a command standpoint.
But Bryan Woo is my focal point. He's my projection model's top fantasy-point projection arm on the board tonight against this White Sox lineup that can strike out a bunch.
This game being in Seattle matters. It's been favorable for pitchers for quite some time. The Mariners staff isn't having its usual level of success this year, but nothing about the park has changed, and we're still seeing more strikeouts in games played there — a 24% strikeout rate in Seattle games compared to 22% everywhere else.
White Sox vs Mariners Pick, Betting Analysis
Woo enters this matchup with back-to-back nine-strikeout games and 28 total whiffs across those outings against the Braves and Astros.
The White Sox are second in the league in home runs now, so you can never fully count on a starting pitcher to stay under an earned-runs prop. But opposing starters are usually piling up strikeouts and working efficiently if they're throwing enough strikes to force the White Sox to swing the bats.
This is an offense that likes to walk and likes to hit the long ball. Woo is going to come right after them, and that should work in his favor tonight.
Pick: Bryan Woo 7+ Strikeouts (+112)
