PITTSBURGH -- Jose Contreras' pitching line was a red flag, but general manager Ruben Amaro Jr. said there is no reason for concern.

Contreras, on the disabled list and rehabilitating from September elbow surgery, threw just 11 pitches in single-A Clearwater's opening-day game against Dunedin Thursday. Only four of his pitches were strikes and two were wild pitches.

The 40-year-old righthander started the game for the Threshers, but registered only one out and allowed three runs on two hits, including a home run. He also walked a batter.

"He's perfectly fine," Amaro said. "He's going through the process of a rehab. Somebody booted a ground ball behind him that was ruled a hit and his location wasn't great, but he's perfectly fine physically. He had poor location and got beat up, but that's why he's rehabbing."

Contreras only appeared in three Grapefruit League games for the Phillies and had a 19.29 ERA, allowing seven hits and five earned runs in 2 1/3 innings. He is in the second season of a two-year deal that will pay him $2.5 million this season. There is also a third-year option for $2.5 million that includes a $500,000 buyout.
