Baseball has done many changes with analytics. Swing for the fences, Launch angle revolution. Normal swing even with 2 strikes, Shifting on 1/6 of the plays. Through all of that BABIP does as it always has and floats between .290 and .300. It has been .290 the last couple of years, but it has been down there before. Might it help Kepler with no shift. Maybe, maybe not. It depends on the range the fielders have. There should be some improvement, but if Kepler went back to being more of a line drive hitter would probably do him more good
