When thinking of the top pitchers in baseball, names like Mark Buehrle, Alfredo Simon, Aaron Harang, and Scott Kazmir, will not be on the short list. However, 2014 has shown that these aged pitchers still have something left.
Mark Buehrle: With an MLB-leading 0.64 ERA over 28 IP, Buehrle has gotten off to a truly fantastic start. His strikeout rate is up, his walks are down, and he has yet to allow a HR up to this point. The Blue Jays sorely need him to keep this up if they hope to compete in the AL East.
Alfredo Simon: Thought of as the long man in the Reds bullpen entering the season, Simon was called upon to fill in for the injured Mat Latos and has performed much better than expected. Simon has held opponents to a .170 AVG over his 27.2 IP, striking out 17 in the process. The real surprising factor, other than run prevention, has been ability to go deep in to games, saving a Reds' bullpen that ranks among one of the league's worst in 2014.
Aaron Harang: Where have you been, Aaron Harang? After his career ended in Cincinnati, Harang hasn't been much other than a blip on the radar since with stops with the Padres, Dodgers, Mariners, and Mets. This year has, however, has been a complete 180. Through his five starts, he has tallied 33 K in 31.2 IP, a .139 opponents' AVG, and also threw 7 no-hit innings against the Mets, being pulled due to pitch count. The telling stat, though, has been his high walk rate (10.7%). If he wants to keep this up, that number is going to have to come down.
Scott Kazmir: He only made his return to MLB last year with the Indians, but Kazmir has been exceptional since signing with the A's this past winter. Over his 27.1 IP, he's struck out 24, walking only four batters, maintaining a 1.65 ERA. The telling stat with him, though, could be the abnormally low .219 BABIP. He's been lucky and good thus far. Time will tell if he can keep that kind of luck up over the remainder of his season.
