HARTFORD, Conn. (AP) - Connecticut has a pretty good backcourt in Shabazz Napier and Ryan Boatright. In the second half against No. 1 Louisville, the Huskies' guards were overmatched.
Russ Smith and Peyton Siva, Louisville's backcourt, dominated play in the second half in the Cardinals' 73-58 victory Monday night.
"Both of their guards are so electric and fast," Napier said of his counterparts.
Russ Smith had 23 points and Peyton Siva managed 11 in a foul-plagued 22 minutes for the Cardinals, who played just hours after they moved to the top of Top 25.
The Cardinals (16-1, 4-0 Big East) won their 11th straight game and like the others they relied on their star backcourt and pressure defense.
"They're strong and quick. They're always moving and active," Connecticut's Omar Calhoun said of Louisville's defense. "They move like they're on a string. You always have to be aware and watch what you're doing against them."
Siva, the conference preseason Player of the Year, picked up his second foul just 3:47 into the game. Not only did the Cardinals lose a veteran leader when the senior went out but Smith, the leading scorer at 18.7 points per game, had to assume more of a role in running the offense. It didn't hurt his scoring much, though, as he had 15 points on 7-of-13 shooting as Connecticut took a 34-28 halftime lead.
Siva picked up his third foul with 14:21 to play in the game and he returned to the bench. When he came back in the game with 10 minutes left, Smith went to the bench for treatment. Siva hit a 3-pointer 50 seconds later as part of the game-changing 19-5 run.
"We did a good job of weathering a Peyton Siva storm, with him out," Louisville coach Rick Pitino said. "Once he came back and we weathered that storm, we were able to play much better defense and much better offense."
That is an understatement.
The pressure defense that drops into a matchup zone forced Connecticut into turnover after turnover and when the Huskies did get to shoot it was almost always a miss.
"They deserve the No. 1 ranking," Connecticut coach Kevin Ollie said. "They have talent. They play together. They play hard. Whoever's open they get the ball to. And they have those two amazing guards. Siva and Russ put pressure on our offense and defense the whole night."
Now Ollie has to get the Huskies ready for a trip to Pittsburgh this weekend.
"We've just got to focus in on what we have to do," Ollie said. "We have to make shots. In these types of games you've got to make plays. We have the guards to make plays but unfortunately we didn't make enough tonight."
Connecticut, which shot 53.8 percent from the field in the first half, had just three field goals in the opening 13 minutes of the second half as Louisville went ahead 60-44. The Huskies, who went 9 minutes without a field goal at one stretch, had trouble moving the ball against the fullcourt pressure and 2-3 zone of the Cardinals. The Huskies had seven turnovers in the first 11 minutes of the second half, matching their total in the first half.
"In the second half, we came out and we put it all together," Siva said. "The second half, I just tried to get everybody going. "
Louisville shot 60.7 percent in the second half (17 of 28) and hit an even 50 percent for the game.
Connecticut scored the first basket of the second half for a 36-28 lead but that's when Louisville started looking like the No. 1 team in the country.
They went on an 8-0 run in which Smith had four points and Siva two. That was part of a 19-5 burst that gave Louisville a 47-41 lead with 12:18 to play.
"They came out in the second half, and I don't know what Pitino said to the, but he must have something," Ollie said. "They played very, very hard in the second half, They took it to us."
The only other time Louisville was ranked No. 1 in The Associated Press' Top 25 was the final poll of 2008-09. The Cardinals won the national championship in 1980 and 1986 but the AP does not conduct a post-NCAA tournament poll.
The Cardinals are the third team to hold the No. 1 spot this season along with Indiana and Duke and they celebrated the move with the convincing road win.
