Brewers Counter With May
Dustin May is 6-7 with a 4.13 ERA and 1.25 WHIP over 122 innings for Milwaukee, recording 117 strikeouts and 40 walks. He has allowed just nine home runs, which could prove important against a Seattle lineup that has relied heavily on power while struggling to hit consistently.

Mariners vs Brewers Side and Over/Under Picks
Mariners Spread Play
Milwaukee is priced at -118 on the moneyline and +169 at -1.5, while Seattle sits at +110 with the total set at 7. Gilbert gives the Mariners a legitimate chance to keep this close, making Seattle +1.5 at -207 the preferred spread play for this matchup.
Total Play for This Matchup
Under 7 at -105 is also attractive given Gilbert's elite WHIP and May's ability to limit home runs, pointing toward a much more controlled game than Tuesday's blowout.
- Side Pick: Mariners +1.5 (-207)
- Total Pick: Under 7 (-105)
Final Score Prediction
Gilbert's elite command should keep Seattle within striking distance even as Milwaukee's deeper offense finds a way to edge ahead late.
