One of the problems contributing to Rollins’ troubles has been a noticeable decline in his ability to hit from the left side.
Rollins generates most of his power on pitches inside when batting left handed. Over the past 3 years, that power has faded.
Compare the graphic above to his overall in play rates over the same time.
Rollins puts more balls in play on outside pitches, an area he normally does not produce extra base hits.
It doesn’t help that Rollins prefers to swing at pitches outside either.
So as a LHB, Rollins is swinging more at outside pitches which is dragging down his overall numbers. In the selected zone above, Rollins put up a .295 wOBA despite making contact 91.5% of the time. Until he can prove that he can do some damage on pitches outside, right-handed pitchers will have little incentive to pitch him anywhere else.
