First pitch is set for 4:10 p.m. ET, and my top Athletics vs. Mariners prediction and MLB picks call for a low-scoring game. 

Who will win Athletics vs Mariners today: Athletics moneyline (37%)

For help understanding probabilities, see our odds calculator.

Though Gage Jump has struggled in recent starts, this is a matchup in which he should be able to limit the damage done against him. The Seattle Mariners bats have struggled against southpaws during the last 30 days, ranking 28th in wRC+, 28th in ISO, and 28th in strikeout rate.  

The Athletics have started to turn a corner at the plate, too. They rank sixth in wRC+, third in batting average, and fifth in ISO against right-handed pitching during the last 14 days. Bryan Woo has thrown the ball well recently, but he’s been pitching through a lat injury and could be vulnerable on normal rest, compared to recent outings in which he’s been on extended rest.

The Athletics once again have value on the moneyline as they seek a series sweep this afternoon.

COVERS INTEL: The Mariners rank dead last with a .212 batting average against southpaws in 2026.

Athletics vs Mariners Over/Under pick: Under 7.5 (52%)

Seattle’s bats have not had success against left-handed starters since the All-Star break, ranking 24th in wRC+ during the first five innings of games when facing a southpaw. Gage Jump has been tagged for some crooked numbers in recent outings, but this matchup is still likely to be an uphill challenge for the Mariners offense.

Bryan Woo owns a 2.89 ERA and 4.25 xERA since the beginning of August, allowing two earned runs or fewer in four of his five starts during that span. He will have to contend with a surging Athletics offense this afternoon, but this doesn’t appear to be a spot in which he’s at risk of getting shelled.

Both teams have rested bullpens for the series finale, too, which should limit scoring opportunities in the latter frames.

Athletics vs Mariners home run prediction: Lawrence Butler (14%)

Lawrence Butler has been on a tear since the beginning of August, hitting .355 with a 137 wRC+. Butler has a 9.2% barrel rate and 51.7% hard-hit rate during that span, meaning that he’s been elevating and celebrating a lot.

Bryan Woo has allowed a lot of loud contact to left-handed hitters during the last 30 days: 11.4% barrel rate and a 65.7% hard-hit rate.

Butler has a great chance to leave the yard today.

Athletics vs Mariners weather

Weather shouldn’t have a significant impact on this afternoon’s contest, with the temperature forecasted at 67 degrees around first pitch.
