It will be retroactive to April 13.

The diagnosis is right elbow inflammation. Pivetta was in the fourth inning of a perfect start against the Colorado Rockies when his velocity dropped and manager Craig Stammen walked out and took the ball. Starter Matt Waldron and reliever Alek Jacob have been brought up from Triple-A El Paso with Waldron saying (per Padres media) that he will be starting on Friday in Anaheim against the Angels.

Waldron has had starts for the Chihuahuas with 12 innings pitched and has allowed seven hits and no runs with 12 strikeouts. His last start was April 9, going five innings with two hits and no runs with three strikeouts. Friday would normally be the spot for Germán Márquez, following Walker Buehler on Thursday, but the starting pitchers past today’s game against the Mariners have not been announced by the Padres.

Jacob can be activated and used out of the bullpen until Waldron is needed to start. That would give the bullpen a fresher arm to relieve some stress on the current pitchers. Jacob last pitched 1.
