He doesn't need to be a great BABIP guy to sustain starter level offensive value. Let's just assume his walk and strikeout rates remain exactly the same as they are right now, 7.5%. Lets just take his current rate of power numbers in the FSL and push them forward to the Majors on a rate basis. Here is the line he would put up with a 'normal' BABIP
Code:
PA AB H 2B 3B HR BB K HBP SH SF AVG OBP SLG BABIP
650 586 170 30 6 9 49 49 5 5 5 .290 .347 .408 .302
From a second baseman, that is above average offensive output.
A whole bunch of guys go through the Florida State League who mashed before they got there and mashed after they left, but didn't mash while they were there. It happens all the time.
Ryan Braun and Joey Votto jump immediately to mind.
