Today’s Best MLB Home Run Prop Bets: Top 5 Picks for May 21
#5. Jackson Holliday (+600) - Orioles @ Brewers

Jackson Holliday is carrying a .272 average with six homers and 18 RBIs this year. Beyond the traditional numbers, his 91.1 mph average exit velocity and 47.7% hard-hit rate highlight his knack for squaring up pitches with authority.
#4. Matt Olson (+255) - Braves @ Nationals

Matt Olson remains a staple in Atlanta’s power core with 10 homers and 26 RBIs. He is hitting .240 on the season. His Statcast profile pops with a 94.7 mph average exit velocity and an imposing 18.3% barrel rate. Against a hittable Nationals pitching staff, Olson’s lefty thump is built to take advantage of favorable matchups.
#3. Zach Neto (+310) - Angels @ Athletics

Zach Neto has been a spark plug for the Angels, slashing .278 with seven home runs and 16 RBIs. His plate appearances suggest his timing’s dialed in, and with Oakland’s shaky pitching unit on tap, Neto is primed to capitalize.
#2. Corbin Carroll (+330) - Diamondbacks @ Dodgers

Corbin Carroll’s elite blend of speed and slugging makes him a constant long-ball threat, and this season’s .277 average, 15 homers, and 34 RBIs prove it. The advanced numbers tell the real story: a hefty 93.9 mph average exit velocity and a 17.8% barrel rate. Against the Dodgers, Carroll’s lightning-quick bat speed makes him a dangerous candidate to take one deep.
#1. Wyatt Langford (+650) - Rangers @ Yankees

Wyatt Langford has flashed serious power potential in his rookie campaign, boasting a .250 average with 9 bombs and 20 RBIs. His .819 OPS reflects both pop and patience, and a date with Yankee Stadium’s homer-friendly dimensions is tailor-made for his right-handed bat. At +650, Langford’s odds feel too juicy to ignore given his ability to punish mistakes.
