PEORIA, Ariz. -- Jarrett Hoffpauir's bid to make a positive impression on his new team certainly has not gone the way he's wanted it to.

Hoffpauir, the Padres infielder who was claimed off waivers from Toronto in October, has been sidelined for the second time this spring with a troublesome right quadriceps injury.

"It's frustrating, because you want to be out there every day," Hoffpauir said Thursday.

Hoffpauir is hitting .375 in eight at-bats this spring with one home run. He's mostly a second baseman, but the Padres planned to take a look at him playing shortstop some before the injury.

Hoffpauir missed time earlier in camp, then returned to play only to aggravate the injury.

"Something is there and the more you play on it, the worse it gets," he said. "I probably wasn't quite ready. We tested it and everything was fine, but game speed is a different thing."

Stauffer sidelined with hip flexor injury

PEORIA, Ariz. -- Pitcher Tim Stauffer will be sidelined indefinitely with a sore right hip flexor, Padres manager Bud Black said Thursday.

Stauffer, likely the third or fourth starter in the Padres rotation, was set to pitch Friday in Tempe, Ariz., against the Angels.

"He's feeling better, but we're going to keep an eye on it," Black said. "There's no timetable for his return just yet. We're hoping he can make his next start."

Stauffer suffered the injury covering first base in his last start on Sunday.

"When I broke to cover I tweaked it a little," Stauffer said. "... I pitched two more innings and it lingered. But I can still throw and get my work in."

Stauffer has been one of the most impressive pitchers in camp, becoming the first of the starting pitcher candidates to reach five innings, doing so in his last start.

In that game, Stauffer allowed one earned run on four hits with three strikeouts and one walk. In his last two starts, Stauffer has allowed one run in nine innings with eight strikeouts.

Stauffer said that he's "limiting running and hard breaks" but is still able to throw. He'll get on a mound in the next day or so, he said.

When asked if this were the regular season if he would be able to pitch, Stauffer nodded.

"I think I could pitch with it," he said.
