The Mariners are entering this series off a loss and lost their 4-game series against the Los Angeles Angels 3-1 in their last series. They enter this game with a 52-47 record overall and have a home record of 30-19. This is the 3rd game of a 3-game series with the Astros on Sunday with the 2nd game of this series still to be played on Saturday. The Mariners lost the 1st game of this series on Friday.

The current betting odds have the Astros listed as a slight favorite in this game according to Draftkings Sportsbook. The Astros have looked good in their games this season with their 51-46 record overall which has them in 1st place of the AL West, passing the Mariners in the division with their win on Friday night. They haven't looked great in their road games though, going 23-25 in those. Meanwhile, the Mariners have looked really good in their games this season with their 52-47 record overall which has them in 2nd place of the AL West now, and they have been slipping lately. They have also looked great in their home games with their 30-19 home record, but they went into the All-Star break in a bit of a slump and are now 4-6 in their last 10 games. They are going to have Woo on the mound here and he has been a solid starter for them with his 3-1 record and his 2.45 ERA. As good as he has been this season, the team hasn't been finding a lot of success with him lately. They have lost 3 games in a row with him starting and he also gave up 4 earned runs in his last start which won't help against this Astros lineup that has been getting hot and looking to win this series so they can start pulling away in the division now that they have the lead. The Astros are going to have their own stud on the mound here with Blanco and he is 9-4 with a 2.56 ERA. He only gave up 2 earned runs in his last start which has been a common theme for him this year, and the team has won 2 of their last 3 games with him starting too. Blanco has been really consistent all season and the Mariners haven't been good on offense all year and in their games lately too. The best way to place a bet here is on the Astros to win this game.

“We have clawed our way through a very difficult stretch early in the season and find ourselves tied in first place — just proud of that group. They have never stopped fighting. They never stopped believing. And this is far from over but just to find ourselves in this position, it feels great.” - Joe Espada after his team’s win against the Mariners in their game on Friday.

“Our group understands where we’re at. Offense has been a struggle for us, trying different things to unlock it and get it going. Just not happening right now.” - Scott Servais after his team’s loss against the Astros in their game on Friday.
