Knehr will be called up from Triple-A El Paso to start the second game of Tuesday's doubleheader with the Rockies at Petco Park, Jeff Sanders of The San Diego Union-Tribune reports.
Knehr will be pitching for the Padres for the first time since July 12 and just the fourth time all season. He hasn't allowed a run through 8.1 big-league innings in 2022, but he owns a 6.85 ERA and 1.64 WHIP across 67 frames at Triple-A.
