The Mariners are coming into this game with a 35-28 record this season and they have been playing well in their recent games. They are coming off of a 2-1 loss to the A's in their last game, but they have still won 4 of their last 5 games and they are going to be hungry to bounce back here and win this series as they are currently leading the AL West right now and these are series' they cannot be losing. They are going up against an Athletics team that is 25-38 this season and has not been playing well in their recent games. They are coming off of that 2-1 win, but they have still lost 2 of their last 3 as well as 5 of their last 7 games. Their offense has not been good recently either, averaging 2 runs scored per game in their last 3 games and not scoring more than 3 runs in each of their last 3 as well as 4 of their last 5 games. Those offensive troubles are going to continue here with Bryan Woo starting for the Mariners in this game as he is 2-0 with a 1.30 ERA this season. He has been very good in his 5 starts as he has not allowed more than 3 earned runs in any of his starts, and he has allowed just 1 earned run or less in 4 of his 5 starts this season. He has also pitched at least 6 innings in each of his last 3 starts, not giving up any runs in 2 of those. JP Sears is starting for the A's in this game and he is 4-4 with a 4.01 ERA this season. He has not been great in his recent starts either as he is coming off of a start which he allowed 4 earned runs in and he has allowed at least 4 earned runs in 2 of his last 3 as well as 3 of his last 5 starts. The Mariners have the better pitching matchup in this game and the offense has been better for the Mariners in their recent games as well. The Mariners will win this game.
