The Seattle Mariners head to Sutter Health Park on Friday, September 11 to open a series against the Athletics, with first pitch scheduled for 9:40 PM ET. George Kirby takes the ball for Seattle against Athletics starter Jeffrey Springs in a late-season regular season matchup that carries real weight for both clubs. This one is available on Mariners.TV and 710 AM Seattle Sports for fans tuning in from the Pacific Northwest.

Starting Pitchers: George Kirby vs. Jeffrey Springs

George Kirby is Seattle's assignment when you need a quality start and you need it now. The right-hander has built a reputation as one of the more reliable arms in the American League, known for his exceptional command and an ability to limit free passes. His ability to attack the strike zone consistently gives the Mariners a genuine chance to win any time he takes the mound, and a road start in Sacramento is no exception.

Jeffrey Springs lines up on the other side for Oakland. Springs is a left-handed pitcher with experience as both a starter and reliever at the major league level. He's capable of keeping hitters off-balance with a varied arsenal, and the Athletics will look to him to keep Seattle's lineup in check through the early innings.

Keys to Watch for the Mariners

  • Kirby's command: Kirby's value starts with his ability to locate pitches and avoid walks. The fewer baserunners he allows, the more miserable a night it becomes for Oakland's offense.
  • Capitalizing against Springs: Springs can be effective in short stints, so Seattle's lineup will want to work counts early and make him earn every out. The longer the at-bats, the better the Mariners' chances of getting into Oakland's bullpen.
  • Road discipline: Late-season road games on the West Coast with a late first pitch demand focus. Seattle needs to play clean, disciplined baseball — minimize errors, don't give the Athletics extra outs.
  • Bullpen management: If Kirby goes deep into the game, Seattle's bullpen gets a lighter load heading into the rest of the series. That matters in September.

Prediction

Kirby is the best reason to like Seattle's chances tonight. He limits damage, he works efficiently, and he gives the offense time to solve Springs. This figures to be a tight, low-scoring game — the kind Kirby tends to win. Give the edge to the Mariners, 3-1.
