Who will win Mariners vs Rangers today: Rangers moneyline (-113)
While Jacob deGrom did allow three earned runs in 4 2/3 innings in his season debut, he’s held the Seattle Mariners lineup to a .231 average across 78 at-bats. The righty also had a 2.35 ERA at home last season, and the M’s are hitting .193 against right-handed pitchers.
Logan Gilbert, meanwhile, has been getting hit around. He sports a 6.75 ERA already, surrendering eight earned runs in 10 2/3 frames.
Gilbert’s underlying metrics suggest he’s been somewhat unlucky (2.82 FIP vs 6.75 ERA). However, he’s also surrendered a ton of hard contact early (42.9%) and has seen an uptick in home runs allowed dating back to last season.
COVERS INTEL: Seattle is fifth-worst in the big leagues in team strikeouts, and deGrom is an elite power arm (26 Ks in 78 at-bats against the Mariners).

Mariners vs Rangers Over/Under pick: Under 7.5 (-115)
Two of the last four meetings have cashed the Under, and more importantly, we have two very good arms going to battle here. DeGrom is in a prime position to deal, and while I do believe the Texas Rangers offense will finally break out of the slump and score runs, I also don’t expect Gilbert to give up a ton of runs.Â
Even with an influx of hard contact and home runs surrendered, Gilbert limits damage by missing bats at an elite rate. His 32.3% strikeout rate helped him post a 3.44 ERA last season.
While deGrom’s ERA was north of five against the Mariners in 2025, Seattle’s offense is struggling, and its core pieces have yet to produce.Â
Mariners vs Rangers odds
Moneyline: Seattle +108 | Texas -113
Run line: Seattle +1.5 (-210) | Texas -1.5 (+175)
