INDIANAPOLIS, March 17 (UPI) -- Louisville, Kansas, Gonzaga and Indiana each were awarded a No. 1 seed by the NCAA Tournament selection committee Sunday.
The top overall seed went to Louisville (29-5), which charged down the stretch with nine straight victories, including eight by double-digit victory margins.
The second-ranked Cardinals blew out No. 18 Syracuse in the Big East Tournament title game, earning the top spot in the Midwest Region.
Third-ranked Kansas (29-5) got the nod in the South Region, while Gonzaga (31-2), which ended the season ranked No. 1, will take a 14-game winning streak into the West Region.
The selection committee, meanwhile, wasn't deterred by Indiana's loss in the Big Ten Tournament quarterfinals, handing the No. 4 Hoosiers (27-6) the top seed in the East Region.
Their Big Ten regular-season championship figured to have played a role in the decision.

It was an emotional victory for Nadal, who celebrated by falling to his knees by the net after shaking hands with his opponent.

Raikkonen wins first Formula 1 race of '13
MELBOURNE, March 17 (UPI) -- Kimi Raikkonen, using only two pit stops Sunday, won the Formula 1 season-opening Rolex Australian Grand Prix in Melbourne.
While most drivers were pitting three times in the race, Raikkonen and the Lotus-Renault team stopped just twice and that strategy allowed him to take the lead for good on the 43rd lap.
Raikkonen completed the 58 laps of the race at the 3.295-mile Melbourne Grand Prix Circuit in 1 hour, 30 minute, 3.225 seconds. He also had the fastest lap of the day in just less than 90 seconds near the end of the race.
Raikkonen started at No. 7 in the grid after Vettel and his Red Bull teammate Mark Webber claimed the top two starting positions. Raikkonen quickly moved to fourth and worked into the lead in the 23rd lap.
He briefly lost the lead after a pit stop in the 34th lap but was back in front by the 43rd and controlled the race from there.
The 2013 Formula 1 season continues next Sunday at the Malaysian Grand Prix in Kuala Lumpur.
