Krol has yet to put everything together and pitch effectively over any length of time. But he changed his attitude and altered his work ethic last offseason, and that carried over into spring training. If he continues to develop, he could be a very effective relief pitcher at some point. He has very good stuff. But he didn’t fare well in 2015.
Numbers: 2-3, 5.79 ERA, 1.71 WHIP, .287 opp. BA
