The Giants recalled Black from Triple-A Sacramento ahead of his start Saturday versus the Marlins.
The loss of Robbie Ray (hamstring) created an opening in the Giants' rotation, and Black will now come up from the minors to plug the gap. The 24-yera-old righty hasn't been impressive in his MLB career so far (8.79 ERA through 14.1 innings), but he's built some momentum in Triple-A with several consecutive solid outings, and he'll have the benefit in facing a Marlins offense that ranks 29th in the big leagues in total runs scored this year (509). Austin Warren was optioned to Sacramento in a corresponding move.
