The Betting Insider’s Brewers vs Mariners Preview
Milwaukee Brewers Betting Preview: Priester Throwing Well
Quinn Priester is fresh off a six-inning gem against the Dodgers in which he struck out 10, walked zero and allowed just three hits.
The 24-year-old owns a 3.33 ERA across 13 starts and 18 appearances, but that number is inflated by two blowout starts in early May. He has been lights out ever since, posting a 2.52 ERA and a 1.02 WHIP over his past 13 outings. He induces ground balls at an elite level, holding a ground-ball rate of 58% (top 4% of qualified pitchers), and has improved at avoiding hard contact since the early stages of the season.
The Mariners boast a dangerous lineup at all times, but Priester has shown that he’s capable of navigating through tough spots and finding ways to limit damage.
Seattle Mariners Betting Preview: Can Castillo Stay Hot?
Luis Castillo has been sharp for most of the season, but since the start of July, he’s turned it up a notch.
Over his past four starts, he’s allowed just four earned runs across 24 2/3 innings, while striking out 25 and walking only six. The command has been crisp and he’s getting deeper into games with more efficiency. Opponents are batting .202 and slugging just .236 against him during that stretch. He’s coming off of a gem against the Astros and is back at home, where he has been dominant this season.
He has a 2.06 ERA and a 0.96 WHIP across 11 home starts and has held batters to a .179 batting average. Milwaukee was shutout last night, snapping its 11-game win streak, which presents us with an intriguing “sell high” opportunity.
