TAMPA, Fla. -- South Florida made the most of its first home NCAA postseason game.
Courtney Williams had 17 points and 12 rebounds, Alisia Jenkins added 15 points and No. 6 seed South Florida beat 11th-seed LSU 73-64 in an NCAA tournament first-round game Saturday night.
The announced crowd of 5,560 erupted as the final seconds ticked off.
"I took a moment and went out there (on the court) and was like `wow," USF coach Jose Fernandez said. "This is what we've wanted and worked for."
Next up for South Florida (27-7) in the second round Monday night is No. 3 seed Louisville (26-6), which forced 38 turnovers in defeating 14th-seed BYU 86-53 earlier Saturday.
"We have to be intense ... win or you go home," Williams said.
Danielle Ballard scored 17 points and DaShawn Harden had 16 for LSU (17-14).
"They executed their game plan better than we did, and I don't think it had anything to do with the crowd," Harden said. "I think it had more to do with us letting them disrupt what we wanted to do."
Laura Ferreira hit consecutive 3-pointers in the opening minute of the second half to put South Florida up 44-32. Jenkins then made it 46-32 on a layup. Harden made a pair of 3's that trimmed the LSU deficit to 48-40 3 1-2 minutes into the second half.
Williams broke the South Florida record for points in a season held by Jessica Dickson (682) with a 3-pointer that extended the lead to 60-48 with 13 minutes to play.
"That's exciting," Williams said. "I didn't know it. I'm glad we won."
Williams had 10 points and Jenkins contributed nine to help USF go ahead 38-32 at the break.
Our game plan was to play everybody with equal respect for the mere fact that they had a balanced attack," LSU coach Nikki Caldwell said. "Courtney is an explosive player, and she really pushes tempo for her team. I thought her transition game gave us a problem when she was able to get the ball really quickly down the floor."
Ballard scored nine and Raigyne Moncrief had eight during the opening 20 minutes. Moncrief finished with 13 points and 10 rebounds.
South Florida: This is the Bulls third NCAA appearance. ... USF has its highest seed in this year's tourney. ... Fernandez led the Bulls to the 2009 WNIT title.
LSU: Ballard averaged 23.3 points and 14 rebounds in three NCAA tourney games last year. ... The Tigers entered losing four of seven, including a 74-54 loss to South Carolina in the SEC tourney.
LSU's season comes to an end.
South Florida, 25th in the AP rankings, will remain on its home court for Monday's game second round game with Louisville.
