We're a few weeks out from the MLB All-Star Game—roughly the midway point of the season. Let's ensure we have the best closers possible!
Arizona Diamondbacks
Since May 18th, Mark Melancon has a 3.09 ERA and 1.11 WHIP over 11.2 innings with no walks and eight strikeouts while converting four of his five save chances. He is 11-for-13 in closing situations on the year, with plenty of work needed to correct his poor start to the season. Ian Kennedy only pitched two-thirds of an inning over the past week with no runs, one hit, and one walk.
