Jacob Lopez Is a Lock Tonight: Props & Best Bets vs Athletics

Jacob Lopez takes the mound for the Seattle Mariners tonight against the Oakland Athletics, and the right-hander is coming off a solid stretch of performances that has established him as a reliable mid-rotation arm for the home team. Lopez has been efficient with his pitch mix early in the 2026 season, relying on his fastball-slider combo to induce weak contact. Tonight's matchup against an Athletics lineup that ranks in the middle of the pack for strikeout rate presents an interesting betting opportunity, especially for a Mariners pitcher looking to build momentum at T-Mobile Park. The Athletics have been streaky offensively, and Lopez's recent form suggests he'll have success managing their aggressive early-count approach.

Pitcher Strikeouts: 5.5 | Over -112 / Under -118

Lopez has logged strikeout totals both above and below this 5.5 line in his last three starts, averaging 5.7 strikeouts per outing over that span. The Athletics rank 18th in strikeout rate against right-handed pitchers, meaning they're actually more disciplined than league average at the plate. While Lopez's stuff is sharp and he's comfortable working deep into counts, expecting him to consistently punch out six or more against Oakland's patient approach is optimistic. The under has cashed in two of his last four starts, and the line of 5.5 is positioned right at his season average, making it the safer play.

Recommendation: Under 5.5 strikeouts

Best Bet Tonight

The Under on Lopez's strikeout total is the clearest play on tonight's card. Oakland's lineup does not chase, and Lopez's value comes from inducing ground balls and weak contact rather than pure velocity-based dominance. With the Athletics sitting 24th in the majors in chase rate, you're looking at a pitcher who will need to get ahead in the count and work to strikeouts, which isn't his natural path to success. Lock in the Under 5.5 strikeouts and fade the temptation to ride Lopez's arm talent alone.
