While the injury to the D-backs ace is certainly a blow, it should not be used as an excuse for the rotation failures up to this point.

Burnes, who signed a six-year, $210 Million free agent contract with the Diamondbacks in the offseason, averaged over 31 starts in each of his last four seasons prior to joining Arizona. This season, the 30-year-old was 3-2 with a 2.66 ERA and 63 strikeouts in 11 starts before suffering the injury.
