Mariners vs Mets best bet analysis
The Seattle Mariners pack more punch at the dish away from pitcher-friendly T-Mobile Park, and the added workload is catching up to New York Mets starter Clay Holmes.
Seattle ranks second in wOBA on the highway this season, and Holmes has posted a 5.79 ERA, 1.65 WHIP across his past seven starts. He topped out at just 70 innings as a reliever in 2021 and is up to 126 already across his 24 starts this season.
Additionally, the Mariners are countering with rolling righty George Kirby, and he’s trending in the exact opposite direction with a tidy 2.83 ERA, 0.98 WHIP, and 3.06 xFIP across 13 starts since the calendar flipped to June.
While the Mets have an excellent heart of the lineup, Kirby will hold them in check enough, while the Mariners give Holmes trouble early.
The New York bullpen has had hiccups of late, too, with the Mets sporting a 22nd-ranked 4.56 ERA and 4.41 xFIP over the past two weeks.
