Chicago ? Mark Prior pitched as if he’d been around all season. His fastball was buzzing, his curveball was dipping across the plate and batters were having difficulty getting hits.

After two months on the disabled list, Prior’s season debut was a huge success. But even his sterling six-inning performance Friday couldn’t carry Chicago to a victory.

“It felt good to be out there. I’m not going to lie. I had some anxiety going and probably a little nervousness going into it,” Prior said after allowing just two hits and getting a no-decision as Pittsburgh rallied past the Cubs, 2-1.

“I think I got a little gassed right there at the end, the last two or three hitters,” Prior said of his 85-pitch performance, 55 for strikes.

Prior walked none, struck out eight and showed no signs of the Achilles tendon and elbow soreness that kept him out of the rotation.

“I doesn’t matter how many rehab starts you have. I was probably a little drained because of the excitement of pitching in a big league game,” Prior said.

The Pirates took some of the excitement of the day away when they rallied for two runs in the ninth.

Jack Wilson doubled off Joe Borowski (2-4) and scored on Craig Wilson’s two-out single to tie it. Pinch-hitter Chris Stynes then hit a go-ahead single off Mike Remlinger.

“Anytime you’re facing Prior, you know it’s going to be tough,” Jack Wilson said..
