Best home run picks for Saturday, May 2

• Yordan Alvarez, Astros (+390)
• Jordan Walker, Cardinals (+XXX)

Yordan Alvarez, Astros (+390, BetMGM)

Alvarez battled injuries last year and the worst year of his career in 2025. Well, the star Houston slugger has been punishing baseballs in the early stages of 2026 with 12 home runs and an OPS well over 1.000 as he's on the shortlist of top AL MVP candidates. Alvarez is seeing the ball well with more walks (21) than strikeouts (15), and while he faces a tough young lefty in Boston's on Saturday, it really doesn't matter for Alvarez at this point. Alvarez actually is slugging far better against lefties (.786 SLG) than righties (.667) with five homers off southpaws in just 49 plate appearances. Lefties have also hit slightly better off Connelly (.414 SLG, .687 OPS) than right-handed hitters (.333 SLG, .660 OPS). Alvarez is red hot and he can leave the yard against anyone, and he has power to all fields, too. That can bode well at Fenway Park.
