Alex Rios and his LD%

Someone asked, "Did Rios' BABIP went up 2%p because his LD% went up 2%p?"
I replied, "Possibly." I wasn't sure about the exact number, but I know line drives are the ones with the highest batting average of balls in play.
He replied back, "Would it be possible if he has taken a different approach when swinging knowing that his power numbers aren't there any more?"
I don't know. Maybe. I didn't think 2%p change was that big. So I decided to search for it. Among 94 batters who were qualified for both 2013 and 2014, these are their LD%.
