Red Sox Moneyline (-135)

By Tony Sartori

The only reason the Red Sox are not heavier favorites is that New York boasts one of the best lineups in baseball.

That said, the gap between the two pitching staffs is far wider than the hitting gap.

While the Yankees may have the edge offensively, Boston still ranks among the top seven MLB lineups in runs scored per game, hits per game, slugging percentage and OPS.

Finally, the Red Sox have won each of the past seven meetings between these two clubs.

Pick: Red Sox Moneyline (-135)

Charlie Wright's Astros vs Orioles Best Bet: Expect Few Runs Early

1st Half Under 5.5 (-139)

By Charlie Wright

Dean Kremer is streaky. His ERA always seems to land around 4.00 at the end of the season, but it's an up-and-down path to get there.

The Orioles starter is on one of his hot streaks right now. He's posted a 2.78 ERA over his last 11 starts. His xFIP (3.77) and SIERA (3.72) are a run higher than that mark, though they're still solid.

Kremer cruised through seven scoreless innings against Houston last time out. The Astros are in the bottom three in OPS, wOBA, and wRC+ against righties over the past 30 days.

Cristian Javier is more of a question mark. We've only seen eight innings in the big leagues from him this season. The Astros starter tossed three solid innings last time out against Baltimore before departing with an illness. He's expected to be good to go today.

The main takeaway so far with Javier has been the fastball velocity. His heater is up nearly 1 mph from 2024. It's not back to 2022 levels, but it's in line with where he was in 2023. It's an encouraging development as Javier looks to get back to his pre-injury form.

Baltimore ranks 9th in OPS, wOBA, and wRC+ over the past 30 days. However, they recently lost Adley Rutschman and Jordan Westburg. It's a young, unproven lineup right now.

Pick: 1st Half Under 5.5 (-139)



Bet Labs' Dodgers vs Padres Best Bet: System Recommends the Under

Under 8 (-105)

By Bet Labs

This system capitalizes on an overlooked weather edge in MLB totals betting. It focuses on regular-season games where elevated humidity —ranging from 45 to 95— intersects with moderate temperatures and neutral wind patterns.

Despite assumptions that humidity boosts offense, public bettors are fading these conditions, which actually correlate with suppressed scoring in certain environments.

In these spots, the home team has stayed under in recent games, with their five-game over rate sitting below 40, suggesting low offensive rhythm.

The market has subtly corrected as well, with the total dropping from open to close, and the overall percentage of bets on the over remains modest, between 6 and 29.

These indicators combine to identify under-the-radar under spots where public narratives misalign with actual scoring trends.
