TAMPA, Florida (Ticker) -- Marquel Blackwell passed for 246 yards and three touchdowns as South Florida stretched its school-record home winning streak 18 games with a 31-28 victory over Memphis.
Blackwell, who completed 24-of-26 passes, threw all three TD passes in a 28-point second quarter that enabled the Bulls (7-2) to open a 28-7 halftime lead.
He threw TD strikes of 20 and nine yards to Hugh Smith to give South Florida a 14-0 lead, then found Clenton Crossley for a seven-yard TD with 29 seconds left.
The Bulls hold off Memphis' comeback attempt in the second half to stretch their overall winning streak to five games, matching the third-longest run in school history.
South Florida, which only started a football program in 1997, joins Conference USA next season.

Wimprine completed 32-of-53 passes for 314 yards with a pair of interceptions and also scored on a five-yard run midway through the third period.
Memphis suffered its sixth straight loss and has not won since defeating Tulane, 38-10, on September 21.
