Zac Gallen shines as Diamondbacks face Marlins.

Arizona Diamondbacks pitcher Zac Gallen, who has been overlooked and underrated throughout his career, is quietly putting on a pitching clinic this season. He has a fastball command that reminds baseball executives and scouts of Hall of Famer Greg Maddux, a quiet intensity that reminds people of Jon Lester, and an unflappable demeanor on the mound like Clayton Kershaw. Gallen is 5-1 with a 2.26 ERA, ranking second in the National League with 64 strikeouts, while leading the NL lead with a 0.85 WHIP, strikeout-to-walk rate, innings pitched, and fourth in opposing batting average.
