Chicago Cubs vs Philadelphia Phillies (6:40pm, EST)

Shota Imanaga Under 4.5 Hits Allowed (-145) at BetMGM Sportsbook

After rivaling Paul Skenes for the NL Cy Young award for a majority of the 2025 season, Shota Imanaga has been able to pick back up from where he left off, kicking off his year with an ERA of 2.81, WHIP of 0.813, and a FIP of 2.25.

His success on the mound stems from his incredibly high Whiff Rate, averaging more than one Strikeout per inning.

In a favorable matchup against the Philadelphia Phillies, expect Imanaga to build on his momentum as he faces off against a lineup who ranks below league average in Contact Rate.

Especially with his back end narrowing the width of their gaps in the outfield with their suffocating coverage, surrounding Imanaga with a unit who ranks third overall in Defensive Efficiency.

Shota Imanaga Over 17.5 Outs (-125) at BetMGM Sportsbook

With the Phillies struggling to make contact at a consistent rate, they will be unable to advance their runners into scoring position, lengthening Imanaga’s leash which increases his chances of going the full length of his start.

For some more exposure, place a wager on the Phillies to be held under their team total in the first five innings as well, fading them while Imanaga is on the mound.

San Francisco Giants vs Cincinnati Reds (6:40pm, EST)

San Francisco Giants Team Total Under 4.5 (-117) at Caesars Sportsbook

After grading out poorly in most offensive metrics last year, the San Francisco Giants re-tooled lineup have been unable to round back into competitive form, ranking in the bottom three in RBIs, Runs Scored, and in On Base Percentage.

Even when making contact at a high rate, the Giants drop off in production throughout their lineup leaves them vulnerable to prolonged scoring lulls.

Against the Cincinnati Reds, the Phillies struggles on offense are poised to persist as they face off against Rhett Lowder who is currently averaging an ERA of 3.31 and less than one Hit Against per Inning Pitched.

Lowder’s back end also helps reduce the amount of variance in his starts which helps him keep them off the bases, ranking in the top-10 in Fielding Percentage.

Jung Hoo Lee Under 0.5 Total Hits (+175) at FanDuel Sportsbook

Even when back at full health, Jung Hoo Lee has been unable to get into a groove, averaging less than one Hit per game, a .185 Batting Average, and a .561 OPS.

With Lowder excelling at avoiding contact while supported by a productive back end, expect Lee to continue to be neutralized at the plate and be held without a hit on Wednesday night.

Texas Rangers vs Athletics (9:40pm, EST)

Texas Rangers Team Total Under 4.5 (+108) at FanDuel Sportsbook

After winning their last two games in a row, the Texas Rangers have been able to hold on to their lead in the AL West, sitting one game ahead of the Athletics for first.

A stunning performance when factoring in their lack of production on offense, fielding a lineup who ranks below league average in Hit Rate, On Base Percentage, RBIs, Runs Scored, Strikeout Rate, and in OPS.

Heading into Wednesday night, expect negative regression to rear its ugly head as the Rangers face off against the Athletics rotational pitcher J.T. Ginn who is averaging a WHIP of 0.909 and an ERA of 3.27.

With the Rangers incapable of stringing together their Hits, escalator bet their team total by placing smaller wagers on their alternate unders at the best available odds across multiple sportsbooks.
