Best betting promos and sportsbooks for MLB prop bets [March 31, 2026]

The San Francisco Giants headline Tuesday’s slate of games with a divisional matchup against the San Diego Padres.

It was as disappointing as it gets for Logan Webb in his season debut against the New York Yankees, finishing the contest with an ERA of 10.80 and a WHIP of 2.000.

Luckily for the NL Cy Young contender, he will have a great opportunity to round back into form as he faces off against the San Diego Padres who currently rank near dead last in most offensive metrics.

With fourteen games taking place on Tuesday night, there are plenty of markets to groom through which you can read a detailed breakdown of them below.

San Francisco Giants vs San Diego Padres (9:40pm, EST)

Logan Webb Over 5.5 Strikeouts (+104) at FanDuel Sportsbook

After leading the NL in Strikeouts last year, Logan Webb was projected to build on his momentum and rival Paul Skenes for the Cy Young award.

Unfortunately for the San Francisco Giants ace, he fell hard back down to reality in their season opener against the New York Yankees, conceding nine Hits and six Earned Runs in a shutout loss.

Heading into Tuesday night, expect Webb to recapture the same success he had last year as he faces off against the San Diego Padres who currently reside near the bottom of the board in Contact Rate and in OPS.

If you want to increase your exposure on Webb, you can escalator bet his Strikeout prop by placing smaller wagers on his alternate overs.

San Diego Padres Team Total Under 3.5 (-130) at BetMGM Sportsbook

While struggling to string together their Hits, the Padres have been unable to bring their runners home as their lineup also ranks well below league average in RBIs and in Total Runs Scored.

With Webb avoiding contact while generating Whiffs, expect the Padres to continue to be neutralized at the plate and be held under their team total.

Colorado Rockies vs Toronto Blue Jays (7:07pm, EST)

Max Scherzer Under 1.5 Earned Runs (+110) at BetMGM Sportsbook

In the tail end of his career, the wear and tear on Max Scherzer has started to show, finishing last season with an ERA of 5.19 and a FIP of 4.99.

While his ERA and FIP seem staggering at first glance, it’s worth noting Scherzer was also still able to create Whiffs at a high rate, averaging nearly one Strikeout per Inning Pitched.

Fortunately for the future hall of famer, Scherzer will have a great opportunity to get off to a hot start this season as he kicks off the year with a favorable matchup against the Colorado Rockies who rank below league average in Contact Rate, On Base Percentage, and in OPS.

Especially with his defense limiting the amount of variance in his starts as he is supported by a back end who ranks sixth in Defensive Efficiency.

Vladimir Guerrero Over 1.5 Total Hits (+120) at BetMGM Sportsbook

After playing at a high level last year, Vladimir Guerrero has been able to carry over his success into this season, averaging over one Hit per game and a .971 OPS.

With Ryan Feltner struggling with his command as his WHIP of 1.484 indicates, expect Guerrero to continue to make contact at a consistent rate and clear the over on his Total Hits prop.

New York Mets vs St. Louis Cardinals (7:45pm, EST)

New York Mets Team Total Over 4.5 (-114) at FanDuel Sportsbook

After re-tooling their lineup, the New York Mets have been able to hit the ground running, starting the year ranked in the top half of the board in Contact Rate, RBIs, Total Runs Scored, and in OPS.

If it were not for an ill-advised coaching decision at third base, then the Mets would be 3-0 and tied with Miami for first in the NL East.

In a favorable matchup against the St. Louis Cardinals, expect the Mets to continue to thrive as they face off against Andre Pallante who averaged an ERA of 5.31 and over one Hit Against per Inning Pitched last season.

With the Cardinals back end also ranking near the bottom of the board in Fielding Percentage, the width of the Mets gaps in the outfield will widen, increasing their chances of generating a Hit.
