The somewhat unexpected signing of Madison Bumgarner to a five-year contract with the Diamondbacks certainly enhances the depth of the Arizona rotation. Unlike last year, when we lost Patrick Corbin and Clay Buchholz from the year-end roster to free-agency, this winter the D-backs have had no significant departures. Right now, the 2020 Opening Day starting pitching would appear to be five of (in alphabetical order) Bumgarner, Zac Gallen, Merrill Kelly, Mike Leake, Robbie Ray, and Luke Weaver. Depth behind them would include Taylor Clarke, Jon Duplantier, Taylor Widener and Alex Young from those who pitched in 2019, plus new arrivals J.
Should the Arizona Diamondbacks trade Robbie Ray?
