The current betting odds have the Mariners listed as a favorite in this game according to Draftkings Sportsbook. The Tigers haven't looked good in their games this season with their 54-58 record overall which has them right near the bottom of the AL Central. They haven't been a great road team either with their 24-31 road record this year. Meanwhile, the Mariners haven't looked great in their games this season with their 55-58 record overall which has them right in the middle of the AL West. They have looked great in their own ballpark though with their 32-24 home record this season. The Tigers are 6-4 in their last 10 games and they have looked good lately as they have been trying desperately to get back to .500 and keep themselves in the Wild Card race, but they finally gave up on their playoff hopes at the trade deadline. They decided to be sellers and traded away 2 of their best starters, so now they aren't going to have the best option going in this one. The Mariners are 4-6 in their last 10 games and haven't looked great lately, but they are still right in the AL West race and will be looking to take advantage of the Tigers in a bad situation now. The Mariners are going with Woo in this one and he hasn't looked great this season. He is 7-8 with a 4.56 ERA and he has been giving up quite a few runs this year. He is coming off another bad start in which he gave up 5 earned runs and the team has lost 2 games in a row now with him starting too, but he has looked better in his home starts this year and the Mariners are going to be desperate to turn things around here. The Mariners did trade away Castillo, but they still have a lot more hope for the rest of the season, so look for them to try and build some momentum in this home series. The best way to place a bet here is on the Mariners to win this game.
