A D is high for a guy who posted a 4.82 ERA and 4.34 xFIP and an .848 OPS? Combining offense and defense for Z he was a 1.9 WAR player after missing the last month or so of the season. I'd grade him as a C if his blowup didn't lead (rightly or wrongly) to him being suspended for as long as he was. He didn't get a D. He's at a C+/B- (better than Dempster, Garza, Soto, Russell) And why are you assuming away something that actually happened?
