One of the biggest talking points of it not being sustainable is the batting average with men in scoring position. And it is extremely low. However the man has a WHIP of 1.034, so it is not like many are getting on base anyway. Sure he will regress some. And initially I still considered him to be a very solid BOR starter even with regression. However, if he keeps up the WHIP number he will be a very solid #2 or, at worst, #3 starter even if the BA goes up with men on or in scoring position.
