They are asking him to be "selective" not to simply just take more pitches. They don't want him to just sit around and get into an 0-2 count for the sake of doing so. He's still swinging out of his shoes more often than not. The only difference this year has been is that his SLG is down.
2022: 3.623 P/PA
2023: 3.600 P/PA
He's not taking any additional pitches per PA this season. In fact, it's in line with last season in AA.
Kavadas sees 4.732.
The player that I saw with a lower P/PA than Rafaela was Christian Koss, who is not know for having a very patient approach either.
