STORRS, Conn. -- Katie Lou Samuelson scored 19 points to reach the 2,000-point milestone and No. 3 UConn overcame a sluggish start to beat South Florida 63-46 on Sunday. Megan Walker added 14 points and Napheesa Collier had 12 for the Huskies (14-1, 3-0 American), who have never suffered a conference loss in the AAC. Samuelson is the 10th UConn player to reach 2,000 points. Enna Pehadzic had 17 points and 12 rebounds for injury-plagued USF (10-7, 1-2), which led for much of the first half and trailed by just six points at the half. Tamara Henshaw added 12 points and 10 rebounds. USF led 6-4 early when UConn coach Geno Auriemma decided to pull all five of his starters, resulting in an audible gasp and then applause from the crowd. The Bulls built that lead to 14-6, after a 3-pointer Pehadzic. UConn's starters returned in the second quarter. The Huskies retook the lead at 20-18 on a layup by Walker and never trailed again. A third-quarter steal by Christyn Williams led to a fast-break layup from Samuelson, which put her over 2,000 points and gave UConn a 44-24 lead. USF is 0-27 against UConn, going back to its days in the Big East. The Bulls are far from alone. UConn is 104-0 against the rest of the American Athletic Conference since its formation in 2013, including 89-0 in the regular season.
