The A's figured to make a run toward a playoff spot this season, but the Mariners are also hanging in the hunt, heading into this four-game AL West series in Seattle starting Thursday night. Righty Chris Flexen, having a break-out season for the Mariners, hits the hill here for the home team against lefty Sean Manaea for the visitors.

MLB Betting Odds

Thursday's baseball betting lines opened Oakland at around -135 over Seattle, with an over/under of eight runs. Early betting action then bumped the A's about a nickel to -140.

A's-Mariners MLB Betting Preview

Oakland just swept two games from the Angels earlier this week, winning 4-1 Monday and 6-0 Tuesday. The A's then enjoyed Wednesday off.

Just before that, Oakland dropped two of three games to Cleveland. So the A's are 3-2 since the All-Star break.

Seattle, meanwhile, just split two games at Colorado, winning Tuesday 6-4 but losing Wednesday 6-3. Just before that, the Mariners took two of three from the Angels. So Seattle is also 3-2 since the All-Star break.

At 55-42 and 51-45 overall, respectively, Oakland and the Mariners trail first-place Houston by three and 6.5 games in the AL West. The A's also own the second American League wild-card spot at the moment, 3.5 games clear of third-place Seattle.

These two teams have split six meetings so far this season, each team winning a series on the other's home field.

Thursday's Pitching Match-Up

This pitching match-up is a rematch of a game played back on June 2 in Seattle, a 6-0 Oakland victory.

Flexen, by our strict standards, is 7/17 on quality starts this season and four for his last five. Most recently, 12 days ago, he held the Angels scoreless on three hits through seven innings of a 2-0 Mariners win. And over his last five starts, he's allowed just five runs and 22 hits through 32 2/3 innings, with seven walks against 27 strikeouts.

The Mariners are a solid 13-4 with Flexen this season, 5-1 over his last six starts.

In his only career start against the A's, back on June 2, Flexen gave up five runs and seven hits through six innings and took the loss.

Lefty Manaea is 8/19 on quality starts this year but 0 for his last three. Last Friday, he gave up three runs and seven hits through 5 1/3 innings of a 5-4 Oakland win over Cleveland. But over his last three starts, he's allowed 11 runs – 10 earned – and 20 hits, including five home runs, through 17 innings, with one walk against 19 whiffs.

The A's are 12-7 with Manaea this season but only 1-4 over his last five starts.

In his only start this season against Seattle, back on June 2, Manaea tossed nine innings of four-hit, shutout ball, earning the victory.

A's vs. Mariners Prediction 7/22/21

Flexen's been great as of late, Manaea not as much, but Manaea tossed a beauty in beating Seattle in that June 2 match-up. So we're calling this pitching match-up a push. We're also calling the bullpen comparison a wash. We then move to the splits with the sticks, where we give Oakland a short edge. Looking a bit more big-picture, we expect the A's to stay in the AL playoff race and the Mariners to fade. So we're betting Oakland here for our free baseball betting pick for Thursday.
