PARADISE ISLAND, Bahamas -- Louisville looked like its old self. Cardinals coach Rick Pitino, however, faced a problem he's never had before.
The Cardinals had a rougher-than-expected opening-round game, a 51-46 victory over Northern Iowa, and Pitino looked and sounded upset after the game.
He was a different kind of upset on Friday night.
"I had to go to the bathroom during a timeout," he said almost sheepishly. "I never eat game day. Never once as a college or NBA coach. I never eat game day because my stomach gets really upset. I have to eat here because it's a 10 p.m. start. I wish we'd play a little earlier. But tomorrow I'm not eating no matter what."
The Cardinals (5-0) will face No. 5 Duke in Saturday night's championship game. The Blue Devils beat VCU 67-58.
"We consider it a big treat to play them for a championship," Pitino said. "We feel we got the guys to play in that championship and win."
Louisville was back to being one of the better defensive teams in the nation against the Tigers, forcing 23 turnovers that the Cardinals turned into 31 points. Missouri's Phil Pressey, considered one of the better point guards in the country, had eight turnovers.
"Our guys played a heck of a game tonight," Pitino said. "We had five guys in double figures. We had serious foul trouble and our bench gave us a big lift. That was exciting."
The Cardinals played zone the entire game. Pitino said it was because they didn't have enough time to put in a plan to play man-to-man.
"We were expecting that," Pressey said of the zone. "We just didn't execute. That's what their defense does, force turnovers. I felt I was careless. The mistakes were mental, ones I myself don't usually make."
Missouri's shooting percentage (46.0) looked better than it was considering the Tigers were able to get off 50 shots, 13 less than Louisville which shot 49.2 percent.
"We shot well. It was the turnovers," Missouri coach Frank Haith said. "We just had some careless plays. We have to find a ways to make plays. Guys were trying to make home run plays instead of the easy plays."
Chane Behanan and Peyton Siva both had 13 points for Louisville, which forced 86 turnovers coming in and had double-figure steals in each game. The Cardinals had 12 steals Friday with Smith getting half of them.
Pitino used the same baseball analogy Haith did when describing Smith.
"Russ is a home run player. Every possession you really have your heart in your mouth, but he really hits a lot of home runs," Pitino said. "He bothers everybody, and he allows Peyton to do a lot of good things out there because he is so intense and Peyton knows he is going to gamble. But you have got to give Russ his free reign."
Alex Oriakhi and Pressey both had 15 points for Missouri (4-1), which beat Stanford 78-70 in the first round. Pressey had seven assists.
The Tigers scored the first four points of the second half to get within 39-35. The Cardinals went on an 11-0 run that featured 3-pointers by Smith and Hancock and Missouri was never within 10 points the rest of the way. Of the Tigers' three possessions during the big run, two ended in turnovers, the other with two missed free throws.
Oriakhi had eight rebounds for Missouri, which finished with a 37-32 advantage on the boards.
