Published:

By: Sam Connon

There are a handful of aces taking the mound Tuesday, from Blue Jays veteran Max Scherzer to Brewers trade deadline acquisition Dustin May and Twins righty Taj Bradley. Will Scherzer fall flat against the Orioles again? Which version of May will take the mound in Philadelphia? Can Bradley keep some stellar streaks alive? Here is our full breakdown of where we think each starting pitcher will wind up in the strikeout column.

MLB Strikeout Prop Bets Breakdown

Max Scherzer under 4.5 K (-126), Baltimore Orioles vs. Toronto Blue Jays

Scherzer made headlines with his 10-strikeout outing against the Mariners in late August, but he has otherwise struggled to punch guys out all year long. He has come in under 4.5 strikeouts in 14 of his 16 starts, including seven of his last eight. He also averages 4.6 strikeouts per nine innings on the road, compared to his 7.7 mark at home, which could make Tuesday’s road outing a tough one. Scherzer already posted just three strikeouts when he faced the Orioles in Toronto on Sept. 11, and now he has to face them at Camden Yards. Baltimore averages fewer strikeouts per game at home, too, on top of keeping five straight opposing starters under Scherzer’s line on Tuesday.

Dustin May 4+ K (+106), Philadelphia Phillies vs. Milwaukee Brewers

After posting a 3.54 ERA across his final 19 starts with the Cardinals, May has put up a 5.40 ERA through eight starts in a Brewers uniform. And yet, he has gone for four-plus strikeouts in six of those eight starts, as well as four straight. That brings him to 20-for-29 on the season. Oddly enough, Tuesday marks the first time May has ever faced the Phillies, in either the regular season or postseason. Still, Philadelphia has allowed four straight and eight of the last 11 starters they’ve faced to reach four strikeouts.

Taj Bradley 6+ K (-186), San Francisco Giants vs. Minnesota Twins

Bradley has had a few messy outings over the last month-plus, but he is coming off back-to-back quality starts. He has also recorded at least six strikeouts in six consecutive starts, doing so in four straight road games and 13 of his last 16 appearances overall. As for his opponent, the injury-riddled Giants have struck out 38 times over their last three games alone. Zebby Matthews struck out nine in 5.0 innings in Monday’s series opener, and his 8.0 K/9 this season are a far cry from Bradley’s 10.4 mark. Three of the last four starters or bulk relievers to face San Francisco have hit the six-strikeout threshold, too.
