Rincones (vs RHP) doesn’t have particularly poor bat to ball skills, though he does struggle to elevate the ball for someone with his power (with is 97th percentile for 90th EV and 100th for max). His zone contact and swing and miss vs offspeed are 50th percentile for 90th for AAA hitters and his chase rates are well above average. He is not aggressive in the zone and doesn’t pull the ball. For comparison, Otto Kemp is 29th percentile in zone contact and 17th in whiffs while being below average in chase. That is a long way of saying selectivity (really aggression) is Rincones problem over contact.
