One of the most important contributors to the Diamondbacks’ 11-7 start doesn’t take the field. He’s not in the dugout, either. In fact, he’s rarely with the team. Instead, he sits in his California home, watching games and dispensing information that has helped transform the Diamondbacks’ starting rotation.
Last year, Arizona’s starters ranked dead last in the National League with a 5.19 ERA. This year – and yes, it’s admittedly a small sample size – the Diamondbacks’ quintet of Zack Greinke, Patrick Corbin, Taijuan Walker, Robbie Ray and Shelby Miller is third in ERA (3.35), tied for second in wins (seven) and second in strikeouts (98).
