Approach, approach, approach.
Bregman has yanked how many off speed pitches far but foul? Last night he is patient with one ("let the ball travel" as Blummer says) and gets a double to right center which could have been a triple if the diving defender didn't slow ball as it bounced past him.
The short porches are fool's gold sometimes.
(As for the batter's eye, the hitters either like it or they don't. Who knows what percentage it contributes to home woes? But just because you can prove something with math doesn't mean hitters will believe it. Personally, I think it's ugly. )
