UNDATED (AP) -- The run to the Final Four continues tonight with the start of the NCAA tournament's regional semifinals.
No. 1 overall seed Florida heads into tonight's South Regional game against UCLA in Memphis riding a 28-game winning streak. The 34-2 Gators have one of the nation's stingiest defenses allowing an average of 57.5 points a game. They've held 26 opponents to 61 or fewer points.
UCLA is averaging 81.5 points a game, led by 6-foot-9 guard Kyle Anderson. The sophomore leads the 28-8 Bruins in scoring, rebounding and assists.
One of UCLA's losses came against Stanford, which takes on Dayton in the first half of the Memphis doubleheader. That's a battle of double-digit seeds. The 23-12 Cardinal are No. 10 while 25-10 Dayton is seeded 11th. The Flyers have won 12 of their last 14.
Top West Regional seed Arizona takes on San Diego State is a rematch of an early season meeting. The 32-4 Wildcats beat the Aztecs 69-60 in San Diego on Nov. 14. That was the third of Arizona's 21 straight wins to open the season. San Diego State went on to win 20 straight after that on the way to a 31-4 mark.
Regional semifinal regulars Wisconsin and Baylor open up the doubleheader in Anaheim. The Badgers are there for the third time in four years, the Bears for the third time in five.
Sweet 16 East and Midwest regional action goes in New York and Indianapolis respectively on Friday.
