LAS VEGAS -- Colorado had seen Arizonas defence at work before, in person and in the Pac-12 tournament quarterfinals. Even knowing what was coming, the Buffaloes didnt stand much of a chance. Unable to match Arizona after a close first half, Colorado lost to the fourth-ranked Wildcats 63-43 in the Pac-12 semifinals on Friday night. "We knew they were good defensively and we knew we were going to have to make some shots to beat them. We couldnt get going," Colorado coach Tad Boyle said. "Their defence had something to do with that. Our offence had something to do with that." Arizona (30-3) crushed Utah in its tournament opener behind a record-setting defensive show. The Wildcats didnt peel open the record book against Colorado, but they sure gave the Buffaloes fits. Unlike its previous win over Colorado, Arizona started slow, allowing the Buffaloes to keep it close at halftime. Once they got rolling, Colorado had no answer for the Wildcats defensive pressure and string of highlight-reel plays that had MGM Grand Garden Arena feeling like McKale Center West. Arizona shot 60 per cent in the second half and held Colorado (23-11) to 5-of-22 shooting in the final 20 minutes to earn a spot Saturdays championship game against UCLA or Stanford. Nick Johnson scored 16 points, Rondae Hollis-Jefferson added 12 and eight rebounds for Arizona. T.J. McConnell facilitated the Wildcats offence and spearheaded the top of the D, finishing with 12 points, five assists and four rebounds "Our defence became great in the second half, but our offence found its flow," Arizona coach Sean Miller said. "We shared the ball. We were more ourselves. It was that combination that really broke the game open." Colorado was able to hang with Arizona behind its defence in the first half. But playing their third game in as many days took its toll on the Buffaloes in the second half and they had no pushback when the Wildcats started to race away. Askia Booker had 20 points to lead Colorado, which shot 29 per cent overall and was outrebounded 41-25. Now the Buffaloes have a two-day wait to see if the NCAA tournament selection committee deems them worthy of the bracket. "Im hoping to get in the tournament," Boyle said. "Im not going to be presumptuous and say were in, because these guys werent with us three years ago when our team didnt get in and deserved to get in. I think were in, but thats not for me to decide or anybody else in this room to decide." Arizona put on a show in its tournament opener, flexing its defensive muscles for everyone to see with an overwhelming quarterfinal victory over Utah. The Wildcats held the Utes to 13 first-half points, 39 overall, 12 field goals and 25 per cent shooting -- all tournament records. The 32-point margin also matched the largest in tournament history. Arizona pulled a similar smothering act on Colorado in the teams last meeting. After a 12-point loss in Tucson, Johnson proclaimed Arizona wasnt that good and that the Buffaloes would beat the Wildcats by 20, even with leading scorer Spencer Dinwiddie out for the season. The Wildcats turned the slight into a fury, holding Colorado without a field goal for the opening 10 minutes and shooting 84 per cent in the second half an 88-61 win -- their first in Boulder since 1973. The Buffaloes got off to a better start this time, scoring 8 1/2 minutes sooner. Colorado still had trouble with Arizonas amoebic defence, though, going 10 of 29 from the floor in the first half. But the Buffaloes had something up their sleeve: A little defence of their own. Contesting shots and digging down on the post for steals, Colorado made life much more difficult than it had back in Boulder, allowing them to stay in the game. The Buffaloes held Arizona to 11-of-29 shooting and forced eight turnovers -- five by centre Kaleb Tarczewski -- that led to 11 points. Colorado held Arizona scoreless for over 4 minutes during a 10-2 run that helped the Buffaloes trim Arizonas nine-point lead to 27-24 at halftime. "I thought we stood a lot in the first half," McConnell said. The second half looked more like the game in Boulder. Arizona picked up the defensive intensity even more and started pouring out the highlights to extend the lead. Johnson had one, flying in for a reverse alley-oop dunk and Hollis-Jefferson matched him with a tomahawk dunk over Josh Scott. Gordon provided one on the defensive end not long after that, soaring up for a clean swat on Johnsons one-handed dunk attempt that sent Arizonas fans bursting out of their seats. In just a couple of minutes, the Wildcats were up 51-32 thanks to a 13-0 run, well on their way to the Pac-12 title game. "In the second half, we were sharper," Miller said.

Edmonton opened the season with 14 straight victories before falling Friday night 10-8 to the host Colorado Mammoth in National Lacrosse League action.UNIONDALE, N.Y. -- Leading 3-0 with only 11:25 left, the Colorado Avalanche committed a seemingly meaningless penalty to give the New York Islanders a power play. But then, the Avalanche committed three more infractions over the next 3:44, and the Islanders took advantage to score two 5-on-3 goals. Somehow, Colorado survived Saturday night. The Avalanche regained their composure, and held on to beat the Islanders 5-2 -- the deceptive margin coming as the result of two empty-net goals in the final minute. Matt Duchene scored twice in a 2:44 span to give Colorado that three-goal advantage. Nathan MacKinnon got the Avalanche on the board, and Gabriel Landeskog and Paul Stasny added the empty-netters. Jean-Sebastien Giguere allowed the two 5-on-3 goals, but was otherwise string, stopping 30 shots. Colorado coach Patrick Roy credited his squad for not panicking after giving up the 5-on-3 goals. "I thought we remained pretty calm on the bench," Roy said. "We had a power play that gave us some momentum back. ... And we also had (a) great save. I think (Giguere) touched it with his glove at the end. That was a big save for us." Duchene broke a nine-goal drought to reach 101 for his career. Roy didnt believe Duchene was pressing in search of his 100th goal. "People made a big story of that, but not me," Roy said. "He had chances.every night. It was just a matter of time. And tonight he was resilient. He went to the net, he stayed there, and took advantage of the rebound. And then the second shot was a perfect shot. Right under the bar. It was a beauty." The win snapped a two-game skid for Colorado, and gave it some momentum going into the Olympic break. "Im vvery proud of our players," Roy said.dddddddddddd "Hopefully, our guys have a good 10 days off." For the Islanders it was a disappointing end to the pre-Olympic portion of the schedule. All appeared to be lost in the second period, where they looked extremely sluggish and could only manage four shots on goal. But the flurry of Colorado penalties ignited the New York offence. John Tavares scored his 24th goal of the season to put the Islanders on the board with 8:43 remaining. Just 57 seconds later, Lubomir Visnovsky added another, to cut the deficit to one. The Islanders had the momentum on their side, and a raucous crowd behind them. They also had another 1:55 on the power play. But they were unable to get the equalizer. Islanders coach Jack Capuano was frustrated by the fact that his team was dominant in significant stretches of the first and third periods, but couldnt turn it into a positive result. "Same old story," Capuano said. "We dominated the game, and we dont win the hockey game. ... We had some unbelievable chances. Give their goaltender credit. He played extremely well." Capuano expressed hope that his club will bounce back after the time off. "We will take.three or four days and regroup, and go through some video of the first half, things that we need to work on, and try to concentrate on those areas." NOTES: Landeskog extended his point streak for the Avalanche to nine games. He assisted on MacKinnons first period goal, in addition to the empty netter. ... PA Parenteau was held without a point in his return to the Nassau Coliseum. Parenteau spent two seasons with the Islanders before signing with the Avalanche in the summer of 2012. ' ' '
