Nearly two weeks into the 2026 MLB season and the main topic of conversation remains the Automated Ball-Strike (ABS) system.

Consistent comments about game improvement, instant entertainment, umpire embarrassment and “fire CB Bucknor!” abound.

BetOnline.ag decided to create some unique props for the ABS, which you can find below.

The most overturned calls we’ve seen so far in a single game is 7. The oddsmakers have set the over/under for the highest overturned calls all season at 8.5.

The first week of ABS saw a little more than 50 percent of the challenges successful. The oddsmakers must think that the hitters/catchers are going to get better as the season-long success rate is set at 60 percent.

Mike Estabrook is favored to have the highest percentage of overturned calls this season.

Interesting to see that the book also expects teams to be afforded more challenges next year.

ABS prop bets are subject to change.
