He's actually on a prett good run going back to 2013. 2013: 211IP 3.24 ERA 2014: 196IP 3.95 ERA 2015: 108IP 4.00 ERA 2016: 181IP 3.38 ERA He's not going to continue to strand runners at 90 percent, or give up less than 5 hits per nine, but he doesn't have to, to be an "ace". Let him finish the rest of 2017 at an ERA something close to his average since 2013...how many better starters are there over the last five years?
