LOUISVILLE, Ky.(AP) -- Pittsburgh promised it would learn from its
mistakes after letting a 14-point lead slip away in a loss to
N.C. State last week.

The Panthers proved to be a quick study.

Bill Stull threw for 242 yards and three touchdowns as the
Panthers overwhelmed Louisville 35-10 on Friday night.

Dorin Dickerson caught two of Stull's scoring tosses as
Pittsburgh (4-1, 1-0 Big East) overcame a shaky first half to
hand the Cardinals (1-3, 0-1) their eighth straight loss to a
Football Bowl Subdivision opponent.

Freshman running back Dion Lewis ran for 87 yards, Ray Graham
added 75 yards and a score and Pittsburgh dominated the second
half to take some of the sting out of a stunning collapse
against the Wolfpack.

"We finished the game, which is all that matters," Pittsburgh
coach Dave Wannstedt said. "We won a tough game in a hostile
environment on the road. But we can still play a whole lot
better."

Maybe, but it'll be difficult topping their second half against
the Cardinals. Pittsburgh scored 28 unanswered points and
outgained Louisville 266-134.

"Our mindset was to go out in the second half and get the job
done," Stull said.

While Stull thrived in the second half, Louisville's Adam Froman
stalled. The junior college transfer made his first FBS start
when Justin Burke couldn't play with a bruised sternum and was
battered by the Panthers. He threw for 166 yards and was sacked
six times.

"We're just a couple of plays away," Froman said. "We had a good
game plan. We knew what they were going to do. We just didn't
execute."

Pittsburgh's defense had a little something to do with it.

"Our whole concept is putting pressure on the opponent and
finishing a game," said middle linebacker Adam Gunn, who made
his first start in three weeks after recovering from an ankle
injury. "We kept our foot on the pedal in the second half. I
think our defensive line is the best in the country."

They played like it in the second half, allowing the Panthers to
shake off a lethargic first half that saw the Cardinals take a
10-7 lead.

Stull wasted little time getting going after the break. He
needed just seven plays to give Pittsburgh the lead, hitting
Dickerson with a 37-yard touchdown pass to put the Panthers back
in front.

Froman, a junior college transfer and former wide receiver,made
his only real mistake on Louisville's next possession. He was
scrambling for a first down when the ball was stripped by
Pittsburgh's Myles Caragein. The Panthers recovered at the
Pittsburgh 29 and Stull didn't waste any time taking advantage,
hitting Jonathan Baldwin on a 71-yard scoring play to put the
Panthers up 21-10.

It would be all the cushion the defense needed.

After self-destructing against the Wolfpack, Pittsburgh's pass
rush overwhelmed Froman and the Cardinals. The Panthers entered
the game fourth in the country in sacks per game (4.25), they
bettered that total early in the fourth quarter while sacking
Froman on a 4th and 11 at the Pittsburgh 31 to snuff
Louisville's last real shot.

"We really took last week personal," said defensive end Greg
Romeus, who had 3.5 of Pittsburgh's six sacks. "We want to take
full responsibility. We took on the challenge."

The Cardinals wore all-black uniforms as a "Black Out"
promotion. A similar ploy three years ago propelled Louisville
to a win over West Virginia and an eventual Big East title.

Those days seem long gone.

Louisville fell to 4-11 in the Big East since coach Steve
Kragthorpe replaced Bobby Petrino after the Cardinals won the
2006 Big East title. The problems that have plagued the program
for most of the last two years: penalties and an inability to
stop opponents, reared their head again on Friday.

Louisville was penalized 10 times for 100 yards and allowed the
Panthers to roll up 404 yards of total offense.

"Times (are) tough, but you just have to keep playing,"
Louisville defensive end Greg Scruggs said. "We do our jobs, we
come away with a win. You take away two big plays and we win the
game. They weren't doing anything complicated. They executed and
we didn't and that's why the scoreboard is the way it is."
