Sam Young kept Pittsburgh unbeaten on a night in which the Panthers weren't making many shots.
The 6-6 senior forward scored 21 points, including two critical baskets in the final 1 minute, 51 seconds, and the third-ranked Panthers (12-0) overcame a woeful 33 percent shooting effort in a ragged 56-48 victory at Florida State.
Young's tip-in broke a 48-48 tie and he followed with a jump shot with a minute left that gave the Panthers a 52-48 advantage.
"That kind of put their heads down," Young said.
"The guy made great plays," Florida State coach Leonard Hamilton said. "They made the plays they had to make in that minute stretch and we missed ours."
Pitt nearly wasted a 17-0 run keyed by two three-point shots by Jermaine Dixon that gave them a 43-34 lead with 8:53 left.
Toney Douglas scored 20 points to lead Florida State (11-2), which shot 29.8 percent; no other Florida State player had more than two field goals.
Dixon, who played for Tallahassee Community College the last 2 years, finished with 11 points and DeJuan Blair added 10 points and 12 rebounds, helping Pitt to a 42-36 advantage on the boards. It was Blair's eighth double-double this season.
