Seattle Mariners vs Baltimore Orioles (6:35pm, EST)

Seattle Mariners First Five Innings Team Total Over 2.5: (-115) at BetMGM Sportsbook

After severely underwhelming on offense last year, the Seattle Mariners have drastically elevated their level of play this season as their lineup ranks above league average in Contact Rate and in On Base Percentage. Their consistency at the plate has helped them get into scoring position at a higher rate as the Mariners also rank in the top half of the board in RBIs and in Total Runs Scored.

With Dean Kremer on the mound, the Mariners offense will have a great opportunity to get off to a hot start as the Baltimore Orioles pitcher averages an ERA of 4.35 and a FIP of 4.03. Kremer’s back end also struggles in coverage which increases the amount of contact variance in his starts as the Orioles defense ranks below league average in Fielding Percentage.

Dean Kremer Under 17.5 Outs: (-125) at FanDuel Sportsbook

With the Mariners offense projected to thrive from the opening pitch, Kremer may fail to go the full length of his start. Especially if the Mariners can exploit his struggles with avoiding contact as Kremer also averages more than one Hit Allowed per Inning Pitched. Should the total on his Outs prop cross through the key number of 18, then increase the size of your wager.

Pittsburgh Pirates vs Milwaukee Brewers (7:40pm, EST)

Spencer Arrighetti Under 15.5 Outs: (-135) at Caesars Sportsbook

It has been a severely underwhelming 2025 campaign for Spencer Arrighetti as the Houston Astros pitcher is currently averaging an ERA of 7.43 and nearly two runners on base per inning. While the sample size is small, his low level of play on the mound stems from his lack of individual production as Arrighetti is also averaging a FIP of 4.68 and more than one Hit Against per Inning Pitched.

Unfortunately for the Astros pitcher, the Boston Red Sox will do him no favors in his efforts of rounding back into form as he faces off against a lineup who ranks near the top of the board in Contact Rate, On Base Percentage, and in Slugger Percentage. Expect the Red Sox offense to continue to get into scoring position at a consistent rate and force the Astros to pull Arrighetti early on in the contest.

Alex Bregman Over 1.5 Total Bases: (+100) at FanDuel Sportsbook

Since joining the Red Sox, Alex Bregman has been able to continue to play at a high level as the former Astro is averaging over one Hit per game and a .301 Batting Average. With Arrighetti struggling with his command, expect Bregman to continue to make contact at a high rate. For some more exposure, escalator bet Bregman’s Total Bases prop by placing smaller wagers on his alternate overs

Los Angeles Dodgers vs Los Angeles Angels (9:38pm, EST)

Los Angeles Dodgers First Five Innings Team Total Over 2.5: (-115) at FanDuel Sportsbook

After losing to the Los Angeles Angels 4-7 on Monday night, the Los Angeles Dodgers have the opportunity to round back into form as they face off against Tyler Anderson who has severely underwhelmed on the mound this season. In his 23 starts, Anderson is averaging an ERA of 4.63 and a FIP of 5.51.

Against the reigning World Series champions, Anderson’s struggles will be on full display as he faces off against an offense who ranks top-5 in Team Total Hits and in Total Runs Scored. Especially with his back end struggling to mask his low level of play on the mound as the Angels defense ranks 25th overall in Defensive Efficiency.
