PITTSBURGH -- Padres right-hander Ross Ohlendorf is in familiar territory at PNC Park, where he pitched for the Pirates from 2008-2011.
"It's a little strange in a different clubhouse," Ohlendorf offered. "It's nice to be back, I've been excited about this trip, and it's really nice to be here."
He made 64 starts for the Pirates and went 13-27 with a 4.60 ERA. Pitching at Triple-A Pawtucket for the Red Sox he posted a 4-3 record with a 4.61 ERA. The Padres signed him to a Major League contract on June 4.
Ohlendorf will be making his eighth start of the season on Sunday. Thus far, he has posted a 4-2 record with a 5.61 ERA for San Diego.
"I feel like I've been throwing the ball well since the All-Star break," Ohlendorf said. "I've had five starts, one of them my results weren't that good, but I still felt like I was throwing the ball well. I definitely feel like I've been improving and getting back on track."
Ohlendorf has one career outing against Pittsburgh at PNC Park -- a relief appearance for the Yankees on June 25, 2008, back before he became a member of the Pirates. In that game, he worked 1 1/3 scoreless innings, striking out three.
"Yeah, it will be strange to face some old teammates on Sunday," Ohlendorf said. "It will be fun. I've always enjoyed pitching here -- it will be weird doing it as a visitor, but I'm looking forward to it."
Street hits disabled list with left calf strain
PITTSBURGH -- The news was not good concerning Padres closer Huston Street, who picked up save number 21 on Friday in the Padres wild 9-8 win over the Pirates. Street pulled up lame on the game's final play with a left calf strain. Street was placed on the 15-day disabled list on Saturday.
"It's a real bummer," Padres manager Bud Black stated. "It's one of those things you never like to see obviously, it's part of the game.
"This is a little bit of a blow, but our guys will respond. Our bullpen guys, I think we have five rookies, plus [Luke] Gregerson and the lefty [Alex] Hinshaw. Those guys will step up, I got a lot of faith in those young guys."
Street was on a roll. On Friday, he extended his scoreless-innings streak to 21 1/3. The last time he gave up a run was June 17 in Oakland.
Since then, rival batters have gone 3-for-66 (.045) against Street, who also walked three batters during the run for a .087 on-base percentage. He has 27 strikeouts during the streak.
Street is 21-for-21 in save opportunities this season. He has 13 saves during the streak.
"There's no real timetable other than we've got two weeks to work with it," Street said. "I know if it feels absolutely better tomorrow I can't play. It does feel a little better today."
The Padres recalled right-hander Cory Burns from Triple-A Tucson. Burns, 24, has pitched to a 1-2 record with a 3.14 ERA and three saves in 54 relief appearances for Tucson this year.
Gregerson, Thayer may share closer role
PITTSBURGH -- Right-hander Luke Gregerson could share the Padres' closer job with right-hander Dale Thayer while Huston Street is on the disabled list. Street strained his left calf on Friday.
"We are going to talk about it -- it's fluid," Padres manager Bud Black said. "I think a combination of Thayer or Gregerson, I think is the way it looks.
"Thayer did a nice job when Street went down before, with five saves in five opportunities. You could see a combination of those two guys depending on usage and rest and a number of other factors."
