The current betting odds have the Tigers listed as a slight underdog 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 Mariners haven't looked great lately though, now 4-6 in their last 10 games, and their offense hasn't been putting up many runs lately. They were once leading the division for a lot of the year, but lately they have been sliding down the standings with their offense starting to skid. They are going with Hancock in this one and he has looked good this season. He is 6-5 with a 3.26 ERA, but the team hasn't had a lot of success with him lately. They have lost 2 games in a row now with him starting and he did give up 3 earned runs in his last start too. The Tigers are going with Melton in this one and he has looked great this season. He is 6-1 with a 1.75 ERA and he hasn't been giving up many runs all year. The team has had a lot of success with him lately, winning 5 games in a row now with him starting, and he gave up no runs in his last start which has been a common theme for him all year. The Tigers offense has also been getting hot lately as they have been putting up a ton of runs and they have the momentum on their side after sweeping the Athletics in their last series. The best way to place a bet here is on the Tigers to win this game.
