PITTSBURGH (Ticker) -- Miami's second trip to Pennsylvania this month ended just like the first -- with an easy victory.
Clinton Portis ran for 131 yards and a career-best three touchdowns as the top-ranked Hurricanes rolled to their 12th consecutive victory, 43-21 over Pittsburgh in a Big East Conference game.
Miami opened the season on September 1 with a convincing 33-7 rout at Penn State. After crushing Rutgers, 61-0, in their Big East opener a week later, the Hurricanes actually fell behind in their first trip to Heinz Field.
But Portis went around the left side from two yards out with 6:17 left in the first quarter to put Miami (3-0, 2-0 Big East) in front for good, 13-7.
Less than four minutes later and one play after Pittsburgh quarterback David Priestley fumbled, Ken Dorsey hit Andre Johnson for an 18-yard touchdown and the Hurricanes were rolling.
After putting up impressive numbers in his first two games, Dorsey completed 19-of-33 passes for 223 yards with one TD and an interception. He improved to 17-1 as a starter.
A 24-yard field goal by Todd Sievers gave Miami a 23-7 halftime lead and Portis extended it with a one-yard run, reversing his field before racing to the left side midway through the third quarter.
Sievers connected again from 28 yards and freshman Willis McGahee scored on a five-yard run to cap a string of 34 unanswered points and extend the Hurricanes' lead to 40-7.
Rod Rutherford threw a touchdown pass and ran for another late score for Pittsburgh (1-2, 0-1), which has lost 12 of the last 13 games in the series.
Miami took the opening kickoff and moved 63 yards in seven plays. Dorsey completed three straight passes for 40 yards before turning things over to Portis, who got the call on three straight plays and covered the final 28 yards.
Sievers' extra point was blocked and Torrie Cox returned the ensuing kickoff 56 yards into Hurricanes' territory. Raymond Kirkley carried twice for 42 yards before Rutherford went in from the 2 to give Pittsburgh a 7-6 lead that lasted less than five minutes.
Kirkley was the Panthers' best weapon with 93 yards on 19 carries. Priestley was 10-of-18 for 64 yards and Rutherford 7-of-17 for 111 yards with a touchdown and an interception.
Former Pittsburgh greats Tony Dorsett, Hugh Green and Dan Marino were among the 57,224 at Heinz Field as the Panthers retired Mark May's jersey No. 73.
