Today’s MLB action began earlier this afternoon with 3 afternoon contests, but there are still 4 games left to get underway as of this writing, which means plenty of betting opportunities still on the board!
While a couple of the remaining games are to be played indoors, the MLB weather report is nonetheless worth taking note of ahead of first pitch for the other ballgames. The forecast temperature is on the cooler side in The Bronx, with slight winds coming in from right field around first pitch. We should see more neutral playing conditions in Los Angeles to end the night.
Below, you can find three of my favorite picks for Thursday, May 21st!
Best MLB Player Props for Thursday, May 21st
Here are my top player prop bets for today, with the first pitch scheduled for 6:40 PM ET on Thursday, May 21st:
- Aaron Judge Over/Under 1.5 Hits + Runs + RBIs
- Cody Bellinger Over/Under 1.5 Hits + Runs + RBIs
- Jazz Chisholm Over/Under 1.5 Hits + Runs + RBIs
Aaron Judge OVER 1.5 Hits + Runs + RBIs (-130, Caesars)
CAESARSWhat needs to be said about Judge? He has a 156 wRC+ and .927 OPS against RHP in 2026. Notably, his BB% is significantly lower against same-sided pitching, which is a good thing if betting an over on his hitter props. Toronto’s bulk arm today, Spencer Miles, has good early season numbers against RHB, but those numbers haven’t been built in matchups against Judge-caliber hitters. This is a playable number on the best hitter in baseball – sometimes it’s best to avoid overthinking things.
Cody Bellinger OVER 1.5 Hits + Runs + RBIs (-105, BetMGM)
BETMGMBellinger will face Braydon Fisher in his first plate appearance and likely Spencer Miles in his second trip to the plate. Neither pitcher has been particularly good across the platoon in 2026. Meanwhile, Bellinger has a 141 wRC+ and .847 OPS against RHP. This is good value at the price.
Jazz Chisholm OVER 1.5 Hits + Runs + RBIs (+120, BetMGM)
BETMGMChisholm has struggled against southpaws in 2026, but his 116 wRC+ against RHP is still plenty palatable when getting this price on him as a cleanup hitter. Chisholm has also been on a tear of late, with a .522 batting average and 277 wRC+ across his last 27 plate appearances. It wouldn’t be surprising to see him stay hot this evening in a good matchup.
