The Seattle Mariners will turn to Bryan Woo to help level the series against the Athletics in Game 2.

Woo has been fantastic lately, posting a sub-3.00 ERA over his last five starts and steering the Mariners to wins in 3 of his last 4 starts.

Current Form:

The Athletics have won 3 of their last 4 games, slightly improving their record to 60-88. In their last game against the Seattle Mariners, Donovan Walton belted a two-run homer to outlast the Mariners, 6-5, in extra innings.

Meanwhile, Friday’s result handed the Mariners their first loss in 3 games and second loss in their last 5 assignments. Seattle is third in the AL West with a 69-79 record, 9 games ahead of the Athletics.

Starting Pitchers: Mariners RHP Bryan Woo (11-9, 4.03 ERA) vs. Athletics LHP Gage Jump (6-10, 5.12 ERA)

The Matchup: The A’s have won 4 of their last 5 head-to-head matches with the Mariners. However, they might have to work harder in the next game as they will face right-hander Bryan Woo, who has allowed one run in his last two starts against the A’s.

Our Athletics vs Seattle Mariners Prediction

The Difference Maker: Bryan Woo has powered the Mariners to three wins in his last four starts. In his last outing on September 6 against the A’s, Woo pitched 8 scoreless innings to help the Mariners secure a 2-0 win.

What to Expect: Woo dazzles on the mound anew, putting the clamps on the Athletics, who are averaging 3.3 runs on a .191 BA over their last five games. This match could still be a low-scoring affair since the Mariners are also mediocre offensively this season, but again, another stellar performance from Woo would be enough to clinch a road win.

Fearless Forecast: the Mariners 3, the A’s 1

Our betting prediction for the Seattle Mariners vs. the Athletics: The Mariners -1.5 runs

Prediction:

 

The Mariners -1.5 Runs
