Betting on baseball can be a grind that reaps an enormous reward.
Day-to-day outlooks can be vastly different by starting pitchers, and a wealth of advanced stats can let us know an individual pitcher, a bullpen, or a team is due to positive -- or negative -- regression.

Cincinnati Reds at Miami Marlins
Under 7.5 (-105)
Two of the worst offenses in baseball against righties are the predominant reason for this bet, but a fun debut helps, too.
Eury Perez makes his MLB debut for the Marlins today, and the highly-touted prospect appears to have earned this in full force. The 6'8" fireballer sports a 2.82 xFIP with Double-A Pensacola, including a dominant 35.9% strikeout rate. Perez will get a soft landing spot against Cincinnati, who tout just an 83 wRC+ (tied for sixth-worst in MLB) against right-handed pitching.
The Reds will counter with Graham Ashcraft, and Ashcraft's 3.82 ERA -- playing half his contests at a top-five hitter's park -- isn't totally fool's gold. His 4.11 expected ERA (xERA) isn't bad, and he's allowing just a 35.9% hard-hit rate allowed. Miami has bottom-five marks in wRC+ (80) and OPS (.651) against righties.
This short total for a rookie making his debut makes quite a bit more sense upon further examination.
St. Louis Cardinals at Boston Red Sox
Cardinals ML (-102)
It's strange the Red Sox are favored here. It's even stranger they're getting 63% of bets at this number, so if this is a trap, public bettors have created it.
Boston is sending James Paxton to the mound today. Yes, that James Paxton, the former Seattle lefty who hasn't made a big-league appearance since 2021. Paxton's baseball career is still going, but he's struggled quite a bit in his rehab to return to the big-league club this season. He's posted a 5.29 xFIP with Triple-A Pawtucket.
The Sox also have one of the league's worst bullpens (4.40 xFIP), and they'll have to hold off a Cardinals offense with at least a .738 OPS in both splits. Can they outscore them? I don't think so, either.
Adam Wainwright will toe the slab for the Redbirds today, and Wainwright deserved far better from his debut than his 7.20 ERA would suggest. His skill-interactive ERA (3.47 SIERA) is outstanding behind a minuscule 22.2% hard-hit rate allowed. St. Louis also has the fifth-best bullpen by xFIP (3.84).
I'd favor the Cardinals in every dimension of this matchup.
San Diego Padres at Los Angeles Dodgers
Over 9.0 (-112)
Blake Snell and Trevor May sounds like a pitching duel on the surface, but I wouldn't be so certain.
Of course, baseball fans know the risk with Snell at this point. Behind his gaudy swinging-strike rate (13.4%) lurks plenty of potential for trouble. Namely, that's a 44.3% hard-hit rate and a self-induced 13.4% walk rate. The opposing Dodgers are also no longer a free pass for southpaws; they've posted the eighth-best wRC+ in May (124) against them.
May has his warts, as well. Some sinkerballers can manage the low rate of swinging strikes that he has (6.2%), but just 43.8% of May's balls in play have been ground balls so far. That's leaving plenty to chance, evidenced by a 4.93 SIERA in lieu of his sparkling 2.68 ERA.
The Padres' offense (.680 OPS versus righties) likely just needs to pitch in a bit if L.A. tattoos Snell, but late-game heroics could also save this total. San Diego (4.41) and Los Angeles (4.26) both rank in the bottom half of the league in bullpen xFIP, and these star-studded offenses could deliver after the starters exit.
