The Mariners are entering this series off a win and completed the sweep in their 3-game series against the Cleveland Guardians 3-0 in their last series. They enter this game with a 36-34 record overall and have a home record of 19-17.

The current betting odds have the Mariners listed as a favorite in this game according to Draftkings Sportsbook. The Mariners have looked good in their games this season with their 36-34 record overall which has them right near the top of the AL West and in the division race. They have also looked better in their own ballpark this year with their 19-17 home record. Meanwhile, the Red Sox have looked good in their games this season with their 37-36 record overall, but that record has them right near the bottom of the AL East in a competitive division. They haven't been a good road team either with their 15-19 road record. The Red Sox just swept the Yankees in their last series and have been the much hotter team lately as they are 8-2 in their last 10 games while the Mariners are 4-6, but the Mariners are also coming off a series sweep in their last series and they can take advantage of a Red Sox team that just traded away their best offensive player, Rafael Devers. The Red Sox are going with Buehler in this one and he hasn't looked great this season. He is 5-4 with a 5.01 ERA this season and he has been giving up a lot of runs in his start. He gave up 3 earned runs in his last start too and his team has lost 3 of the last 4 games that he started in. The Mariners are going with Woo in this one and he has been a solid starter for them this year. He is 5-4 with a 3.39 ERA this season and hasn't been giving up many runs in his starts. He did give up 5 earned runs in his last start and the team has lost 4 games in a row now with him starting, but he will be looking to bounce back at home since he hasn't been that bad this season and the Mariners have looked a lot better lately too. The best way to place a bet here is on the Mariners to win this game.

“I think it starts on the mound. You pitch [well], you’re throwing strikes, the defense is going to be better. I think at the end, pitching and defense are the pillars of baseball. You do that consistently, you're going to have a chance to win a lot of games.” - Alex Cora after his team’s win against the Yankees in their game on Sunday.

“You have to adjust pitch by pitch in this league. And the more you think about that, you pay attention, and I think the better success you'll have. I think I do a pretty good job of that. Just pay attention to how they're pitching you, and if it works [for them], they're going to keep doing it. And if not, you see what they're going to do next. Like, I know if I get a hit to the left side, they're going to try to come inside, that type of thing.” - J.P. Crawford after their win against the Guardians in their game on Sunday.
