He should do better going forward but not sure if I'd label him a slow starter given the lack of sample.
I remember he was sent down in 2019 for being bad.
But in 2018 he started in the minor (hitting 350) was called up and hit .267 by end of April (14% of his games played in 2018).
Last year was too small a sample size (we started July instead of April so not sure if he had an effect too). But if we wanted to use lasr year, in his first 9 games (16% of his games played) he was hitting over .300.
He's at .197 with about 13% of games played (assuming he plays 150 games) so still a bit of a drop.
