Time to check in with the best stolen base picks for today. It was a tough day for steals if you were tailing yesterday’s picks. With only 15 stolen bases on the entire slate, it’s tough to nail them down. We missed with Julio Rodriguez as, once again, we went with the wrong Mariner – should have been Victor Robles. And Brayan Rocchio smacked himself a home run instead of just getting on base for a steal. Good thing we went 3-0 with my picks on the Betting Playbook to help us out and stay ahead of the game. Let’s check in with the stolen base prop finder and start the second half of the 2026 MLB season off on the right foot with some winning stolen base picks today.

Best MLB Stolen Base Picks Today:

Locking in the best stolen base predictions means finding the absolute perfect storm of a high-on-base runner and a weak battery. Here are our top two MLB stolen base picks today for Tuesday, July 21:

Favorite Bet: 

Fernando Tatis, San Diego Padres (+270) – While he’s not hitting for the power we want, Tatis Jr. is still doing a monster job on the basepaths, swiping 25 bags on the season and two over his last three games. He’s posting a .340 OBP against righties this season and faces Reynaldo Lopez of the Braves, who has allowed 12 stolen bases on the season. But the real kicker for Tatis is found in the Braves catcher room. Chances are we’ll see Drake Baldwin and his four-percent caught-stealing rate. That should be the boost we need today. 

Randy Arozarena, Seattle Mariners (+274) – We are determined to nail down the stolen bases on this Mariners team, aren’t we? The Reds are throwing Chase Burns, who has allowed a slate-high 16 stolen bases this season, and Arozarena has been tearing up right-handed pitching this season, posting a .378 wOBA with a .394 OBP, and has 15 of his 19 steals against righties this season. Also in our favor is that the Reds catchers, Tyler Stephenson and Jose Trevino, have a combined 17.3-percent caught-stealing rate.
