Free MLB home run picks, odds for May 27: Rafael Devers among best bets for Tuesday HR player props

Red Sox designated hitter Rafael Devers has been one of the most reliable bats in baseball since breaking into the MLB as a 20-year-old in 2017, and he’s off to another hot start in 2025. Devers is slashing .288/.409/.534 with 12 home runs and leads the American League in RBI (48) and walks (43). On Tuesday, he’ll have a juicy matchup against Brewers right-hander Aaron Civale, who has given up four home runs in seven innings of work so far this season. However, you can still find Devers for as high as +400 in the latest MLB home run odds from BetMGM and that value can also be maximized with the latest BetMGM promo code for new users.

Best MLB home run picks for Tuesday, May 27:

Rafael Devers, Red Sox (+400)

Devers is the only thing standing in between Aaron Judge and the AL Triple Crown at the moment. After some initial apprehension about being used as a designated hitter, it appears he’s benefitting. His 94.8 mph average exit velocity this season is a career-high, as are his 58.6% hard-hit contact rate, 16.9% walk rate, 30.3% flyball rate and .943 OPS.

“Devers has cooled off over the last few games, but he was swinging an incredibly hot bat before that. He is hitting .375 with 7 HRs and a 1.156 OPS in the month of May,” SportsLine data analyst Jacob Fetner said. “We set the line at +350 for Devers to hit a HR.” BetMGM is offering the best price for this MLB HR prop.

Ketel Marte, Diamondbacks (+360)

Marte is coming off a career-high 36 home runs in 2024 and also made his second MLB all-star appearance before finishing third in NL MVP voting. He’s been even more productive when healthy in 2025, but did miss a month early in the season with a hamstring strain. He struggled for a few games upon his return but has been absolutely scorching of late and he’ll get to hit from his preferred left side of the plate on Tuesday.

“Marte has been swinging a hot bat this month with eight HRs in just 22 games during the month of May. Marte has also been both really good at home with a 1.023 OPS and really good when facing RHPs (1.089 OPS and 7 HRs),” Fetner noted. “FanDuel is offering strong value considering most other books have this priced around +300.” First-time users can also bet $5 and get $200 in bonus bets if their bet wins with this FanDuel promo code.

Jose Ramirez, Guardians (+600)

It’s been nine games since Ramirez hit a home run, but he’s in the midst of a 19-game hitting streak entering tonight’s action, so he’s seeing the ball well. The six-time All-Star tied a career-high with 39 home runs last season and the switch-hitter has hit seven of his nine home runs from the left side of the plate this season.

“Ramirez is hitting .372 in the month of May with a 1.048 OPS. He is priced all the way at +600 because Dustin May doesn’t give up many HRs, but May has given up 4 HRs in 4 road starts this season,” Fetner said. “The weather is expected to be hitter friendly in Cleveland, and we would set the line closer to +400, so getting +600 is worth a play.” BetMGM has the best pricing for Ramirez and we’re using it for our MLB HR parlay tonight.
