The Diamondbacks placed starter Brandon McCarthy on the 15-day disabled list Saturday with what the team referred to as inflammation of the right-hander's throwing shoulder. The move was made retroactive to Friday, the day after McCarthy allowed six runs on nine hits in just 2 23 innings, his shortest outing of the season.
With McCarthy unavailable, the D-backs called up right-hander Randall Delgado, one of the primary pieces received from the Braves in the Justin Upton trade. Delgado, 23, has gone 1-1 with a 2.16 ERA in his last three starts at Triple-A Reno. In 11 starts overall this season, he is 1-4 with a 6.84 ERA.
Delgado has not yet appeared for the Diamondbacks, but with Atlanta last season, he started 24 games and had a 3.95 ERA while finishing 5-10.
McCarthy is 2-4 with a 5.00 ERA in 11 starts overall this season.
