San Francisco Giants vs Colorado Rockies (8:40pm, EST)

Colorado Rockies First Five Innings Team Total Under 1.5: (+125) at BetMGM Sportsbook

It has been a forgettable 2025 campaign for the Colorado Rockies as they head into the final stretch of the season with a record of 39-99 and a -359 Run Differential. Their low level of play on offense has hurt their ability to remain competitive this year as their lineup ranks near the bottom of the board in Team Total Hits, RBIs, Total Runs Scored, On Base Percentage, and in Slugger Percentage.

Unfortunately for Colorado, their struggles on offense are poised to persist as they face off against Logan Webb who excels at avoiding contact. In his 28 starts, Webb is averaging an ERA of 3.16 and less than one Hit Allowed per Inning Pitched. Even when receiving minimal support from his defense, Webb possesses more than enough arm talent to neutralize the Rockies offense as he averages a FIP of 2.69.

San Francisco Giants First Five Innings Run Line -1.5: (+110) at BetMGM Sportsbook

On the other side of the field, the Giants offense are in a far better position to succeed as they face off against German Marquez who averages an ERA of 6.14 and nearly two runners on base per inning. Especially when he is surrounded by the worst back end in the league as the Rockies defense ranks dead last in Defensive Efficiency and in Fielding Percentage.

New York Yankees vs Houston Astros (8:10pm, EST)

Jason Alexander Under 4.5 Strikeouts: (-146) at FanDuel Sportsbook

While Webb has thrived, Jason Alexander has struggled as the Houston Astros newly acquired pitcher is currently averaging an ERA of 4.61, a WHIP of 1.372, and a FIP of 4.85. His low level of play can be attributed to his low Whiff Rate as Alexander is also averaging more than one Hit Against per Inning Pitched.

Heading into Wednesday night’s contest against the New York Yankees, Alexander’s struggles on the mound are poised to persist as he faces off against a lineup who ranks above league average in Contact Rate and in On Base Percentage. For some more exposure, escalator bet Alexander’s Strikeout prop by placing smaller wagers on his alternate unders at the best available odds across multiple sportsbooks.

Aaron Judge to Record 2+ Hits: (+230) at FanDuel Sportsbook

Since the start of the regular season, Aaron Judge has been in a tier of his own as the reigning AL MVP is currently averaging more than one Hit per game, a .325 Batting Average, and a 1.113 OPS. With Alexander struggling with his command, Judge is in a favorable position to make contact at a consistent rate to help clear the over on his alternate Hits prop.

Philadelphia Phillies vs Milwaukee Brewers (7:40pm, EST)

Milwaukee Brewers First Five Innings Team Total Over 2: (-145) at BetMGM Sportsbook

After a slow start to the year, the Milwaukee Brewers have managed to build up a sizable lead in the NL Central division standings. Their offense has played a major role in their success this season as the Brewers rank above league average in Contact Rate, Slugger Percentage, and in Total Runs Scored.

With Aaron Nola on the mound, the Brewers offense will have the opportunity to get off to a hot start as the Philadelphia Phillies pitcher is averaging an ERA of 6.47, a WHIP of 1.500, and a FIP of 5.04. Should the Brewers team total in the first five innings climb up to 2.5, then reduce the size of your wager.
