I wasn't aware robo umps being used in AAA until reading the below in BA. Numbers are interesting, and probably similar differences across the board, not just EDLA.
But there's one more complicating factor. Triple-A is using automated ball-strikes (ABS) where on Tuesday-Thursday games, all pitches are called by the computer. On Friday-Sunday, umpires call balls and strikes, but hitters, pitchers and catchers can challenge any pitch, with each team allowed three unsuccessful challenges.
And one could say that most of De La Cruz's improvement has come with the ABS system.
Tuesday-Wednesday-Thursday (ABS)
69 PAs, 12 BBs (17.4%)
69 PAs, 18 Ks (26.1%)
Friday-Saturday-Sunday (Challenge System)
75 PAs, 8 BBs (10.6%)
75 PAs, 24 Ks (32%)
