Tampa Bay Rays vs Toronto Blue Jays (7:07pm, EST)

Toronto Blue Jays Team Total Under 3.5 (+114) at FanDuel Sportsbook

After nearly winning the World Series last year, the Toronto Blue Jays have fallen hard back down to reality this season, fielding a lineup who ranks well below league average in Hit Rate, RBIs, Runs Scored, On Base Percentage, and in OPS.

Their struggles on offense makes them vulnerable to falling into prolonged scoring lulls, plummeting their probability of winning on a nightly basis.

Heading into Monday night’s divisional contest against the Tampa Bay Rays, expect the Blue Jays struggles to continue to be a thorn in their side as they face off against Nick Martinez who is averaging an ERA of 2.65 while giving up less than one Hit Against per inning.

Especially with his back end excelling in coverage, starting a group who ranks fourth overall in Defensive Efficiency.

Nick Martinez Over 17.5 Total Outs (-115) at BetMGM Sportsbook

With the Blue Jays struggling to get on base while Martinez is creating Whiffs at a high rate, the length of the Ray’s pitchers leash on the mound will grow, increasing his chances of going the full length of his start to help clear the over on his Outs prop.

If the total on Martinez’s Outs prop crosses through the key number of 18, then reduce the size of your wager.

New York Mets vs Milwaukee Brewers (7:40pm, EST)

Jacob Misiorowski Under 3.5 Hits Allowed (+110) at BetMGM Sportsbook

At the halfway point of the season, the Milwaukee Brewers Jacob Misiorowski’s odds of winning the NL Cy Young award have skyrocketed, entering the second half of the year with an ERA of 1.62, a WHIP of 0.757, and a FIP of 2.09.

Misiorowski’s success on the mound stems from his elite power and command, generating more than one Strikeout while giving up less than one Hit Against per inning.

In a favorable matchup against the New York Mets, Misiworoski will be able to keep a clean sheet by exploiting a lineup who ranks well below league average in Hit Rate and in On Base Percentage.

The Brewers will also narrow the width of the Mets gaps in the outfield, surrounding their ace with a defense who hovers near the top of the board in Fielding Percentage.

Jorge Polanco Under 0.5 Total Hit (-120) at BetMGM Sportsbook

Since the start of the regular season, Jorge Polanco has underwhelmed at the plate, generating less than one Hit per game and a .169 Batting Average.

With Misiorowski painting the strike zone while aggressively attacking the box, Polanco will continue to struggle with barreling up the ball and be held without a Hit.

Chicago White Sox vs Texas Rangers (8:05pm, EST)

Jacob deGrom Over 6.5 Strikeouts (-131) at Caesars Sportsbook

After going 6-4 in their last ten games, the Chicago White Sox have been able to rival the Cleveland Guardians for first in the AL Central.

Even during their hot stretch of play, the White Sox have still struggled with making contact, ranking in the bottom half of the board in Hit Rate and in Strikeout Rate.

Unfortunately for the White Sox, their struggles with making contact will continue to persist against the Texas Rangers Jacob deGrom, facing off against an arm who is averaging a FIP of 3.40 while generating nearly seven Strikeouts per game.

For some more exposure, escalator bet deGrom’s Strikeout prop by placing smaller wagers on his alternate overs at the best available odds across multiple sportsbooks.
