D-Backs see pitching prospects ready for big league call-up

The Arizona Diamondbacks are looking at several pitching prospects to potentially assist the big league team this season. Mitch Bratt, with a 2.84 ERA at AAA Reno, has impressed in his first taste of higher-level competition. Kohl Drake has struggled, posting a 7.83 ERA in 14 starts, while Spencer Giesting is performing well with a 2.87 ERA in limited appearances. The urgency for these prospects to contribute has increased due to injuries among current pitchers and the potential for future roster moves. The D-Backs are in a postseason chase, making successful call-ups critical.
