Mariners vs Brewers MLB Betting Preview
Seattle Mariners Betting Preview
This one sets up as an interesting spot for the Mariners, especially with Julio Rodriguez having a strong track record against Milwaukee. He’s hitting .297 (11-for-37) with two home runs and five RBIs in nine career games against the Brewers.
Seattle comes into this matchup at 59-66 and 26-37 on the road. Bryce Miller, however, has struggled lately, posting a 6.06 ERA with 16 hits allowed over his last three appearances. He’ll need to find a way to limit the Brewers’ offense.
Milwaukee Brewers Betting Preview
Milwaukee, meanwhile, is 77-48 and has been excellent at home with a 41-22 record. Kyle Harrison gets the ball looking to bounce back after a rough outing in San Diego, where he allowed eight runs in just 4 2/3 innings.
Harrison hasn’t exactly been sharp lately either, carrying a 7.24 ERA over his last three appearances. With both starters coming in with some question marks, I’d rather trust Milwaukee’s overall form and home record in this matchup.
Mariners vs Brewers Pick, Betting Analysis
J-Rod is having an off year, but these odds are far too high.
Kyle Harrison is an extreme fly-ball pitcher vs. righties and has allowed a high 1.61 HR/9.
This ballpark is an upgrade for J-Rod compared to T-Mobile Park, and he is far too good to be priced this high in this spot.
I have the true odds around +420, making this a great bet.
