ST. LOUIS -- Right-hander Andrew Cashner took another step toward rejoining the rotation on Wednesday, as he continued to build his pitch count with a rehab start at Triple-A El Paso.
Cashner, who last pitched for San Diego on June 18 before being sidelined with soreness in his right shoulder, threw 2 2/3 innings (63 pitches), surrendering two home runs.
"Cash felt good," manager Bud Black said. "Got his pitch count to 63 pitches and felt good. Didn't really command the fastball all that great, but his stuff was fine, which is the main thing, and he built his pitch count."
Cashner returned to the hill with a rehab start on Aug. 8, throwing 24 pitches at Class A Advanced Lake Elsinore. Wednesday's outing keeps him in line to make another rehab start at Triple-A on Monday before likely returning to the Padres' rotation next week.
Before hitting the DL, Cashner posted a 2.36 ERA in 12 starts, allowing two runs or fewer eight times.
Utility infielder Jace Peterson, who joined the Padres in St. Louis on Thursday, played behind Cashner on Wednesday.
"[He] really wasn't necessarily trying to overpower anybody like he can, he was just kind of feeling it out, and I think he threw the ball well," Peterson said. "The ball jumped when he wanted it to, and he put it where he wanted to."
