First reaction to ABS Challenge was no big thing business as usual. IMO when everything is said & done it’s going to a lot bigger/more important than we 1st thought. Consider the following; 1) The RE(Run Expectancy) is calculated using the following 3 game states( 3 outs x 8 base states x 12 counts) which adds up to 288 different # of expected runs. 2) To get a Win Expectancy you have to factor in 9 innings, the top or bottom of the inning & 21 different score differentials. That leaves you with 108,864 distinct game states, each with a win a win probability for each team. 3) All pretty complicated. Let’s just say that each successful challenge irrespective of game states is worth 0.181 runs. 4) Going in to games catcher/hitters have a decent idea of where umpires lose & win challenges. Now you have to be aware of the game states. Maybe you color code it from the dugout or 3B coach(Thumb up,down or sideways) before each pitch. Red no challenge/Yellow 50/50/Green when in doubt go for it. I TRULY BELIEVE THAT AT THE END OF THE SEASON THE TEAMS THAT MANAGE THIS THE BEST WILL GAIN A DISTINCT ADVANTAGE. If this subject interests you, there is an excellent site taptochallenge.com that covers this in extreme detail.

The ABS challenge system has been a learning process that’s felt almost experimental. But when all’s said and done, there’s less to complain about, @chadjennings22 writes. Full story: nytimes.com/athletic/7167396…

It took all of five days for MLB's ABS challenge system to show why it might have a bigger impact on the sport than the pitch clock, bigger bases or the extra-innings “ghost” runner. Here’s a look at the umpires with the highest overturn percentages.
