The current betting odds have the Mariners listed as a slight underdog in this game according to Draftkings Sportsbook. The Brewers have looked great in their games this season with their 77-48 record overall which has them right at the top of the NL Central with the best record in MLB. They have looked great in their own ballpark too with their 41-22 home record this season. Meanwhile, the Mariners haven't looked good in their games this season with their 59-66 record overall which has them right in the middle of the AL West. They haven't been a good road team either with their 26-37 road record this year. The Mariners have looked terrible lately and they are 3-7 in their last 10 games now, but they are coming off a series win over the Astros and they are still in the Wild Card race in the AL. The Brewers are coming off a big series win over the Dodgers, but they are only 5-5 in their last 10 games and have been cooling off. The Brewers are going with May in this one and he hasn't looked great this season either. He is 6-7 with a 4.13 ERA and he was having a lot of trouble on the Cardinals this year. He has looked better lately, giving up 1 earned run in his last start and the team winning 2 of their last 3 games with him starting, but that hasn't been a common theme for him this year. The Mariners haven't had a good offense this season, but lately they have been putting up a ton of runs and they are going to be desperate to get hot and stay in this playoff race. The Mariners are going with Gilbert in this one and he has looked good this season. He is 9-7 with a 3.28 ERA and the team has been having a ton of success with him lately. They have won 4 of their last 5 games with him starting and he is coming off a great start giving up no runs which has been a common theme for him lately. This is a great opportunity for the Mariners to take a game in this series now that they are starting to get hot. The best way to place a bet here is on the Mariners to win this game.
