The Arizona Diamondbacks did not have a great rotation last season. They had six pitchers make 15 or more starts. The non-Zac Gallen and Merrill Kelly arms combined for an ERA of around 5.50. But the Diamondbacks have solidified their starting five by adding Eduardo Rodriguez to the depth chart. As of right now, the Diamondbacks have one of the best starting rotations in the National League. It definitely has the potential to be the best starting five in the NL and one of the best in all of Major League Baseball.
There's still a lot of time between now and Opening Day 2024. The Diamondbacks could still make another move to solidify the back end of their starting rotation. But if the season were to start tomorrow, who would the Diamondbacks trot out there as their starting five pitchers?
