Doha, Qatar (SportsNetwork. Cheap Nike Air Force 1 Ireland .com) - Towering Croat Ivo Karlovic stunned world No. 1 star Novak Djokovic in Thursdays quarterfinal action at the season-opening $1.22 million Qatar Open. The 6-foot-10 Karlovic, the tallest player in the history of the ATP World Tour, served his way past the Wimbledon champion Djokovic in a 6-7 (2-7), 7-6 (8-6), 6-4 decision in 2 hours, 16 minutes on the hardcourts at Khalifa International Tennis Complex. Dr. Ivo swatted 21 aces, including four straight to close out the final game of the match. The Croat recorded the only break of serve in the bout in the deciding set. Karlovic is now 2-1 lifetime against Djokovic, including a perfect 2-0 on hardcourts. It was unbelievable, Karlovic said during his on-court interview following the match. When I arrived here, I didnt expect that one. He wasnt able to show his full range because it was windy. I just focused on my game and in the end I was a little luckier. Karlovic also claimed his second career victory over a world No. 1, with his previous win over a top-ranked player coming at the expense of Roger Federer in Cincinnati back in 2008. Also on Thursday, fourth-seeded Spanish veteran David Ferrer whipped German Dustin Brown 6-2, 6-2 to set-up a semifinal affair with Karlovic on Friday. Doha serves as a tune-up for the Australian Open. Air Force 1 Sale Ireland . Notes on P.K. Subban, Dale Weise, Erik Haula, Mikael Granlund, Ilya Bryzgalov and more.

He managed to save par, and went on to put together his best opening round of the year. Calcavecchia and Wes Short Jr. shot 6-under 66 on Friday at Wakonda Club to share the lead in the Champions Tours Principal Charity Classic. Bobby Clampett, Peter Senior and Shane Lowery were a stroke back. Calcavecchia, who lived in nearby Laurel, Nebraska until he was 13, said the rolling hills of the Wakonda Club reminded him of the course he learned to play on. He finished third in Iowa last season, and four straight birdies on the back nine helped put him atop the leaderboard. "Im comfortable on the course," Calcavecchia said. "Its still tough, and you still have to execute under pressure and handle your nerves and stuff. But the course does suit me." It didnt look that way on the first hole. Calcavecchia sent his approach flying over the green. But he put his next shot within 10 feet and made the par putt for his first and perhaps best save of the day. Calcavecchia entered Friday ranked 63rd in opening-round scoring average, but fifth for final rounds. "It was looking like I wwas going to bogey the first hole right off the hop," Calcavecchia said.

But Short, who has been up and down since opening the season with 10th- and 11th-place finishes, made a birdie putt on No. 18 to tie Calcavecchia. Shorts 66 snapped a stretch of six straight rounds of 70 or higher. "Its been a long road for me. I was hurt for a number of years," said Short, who has long battled back issues. "I put a lot of work into it and its starting to pay off." Clampett, whose best finish was a tie for 29th in March, got stuck in the bunker on the par-4 12th and mishit his approach en route to a bogey. But when faced with a similar shot on the next hole, Clampett holed out from 40 feet for eagle. It was an encouraging start for Clampett, who shot his low round of the year. Jay Haas began his attempt to become just the third player to win the same tournament four times with a 69. But history isnt on Haass side, as no one has rallied from more than two strokes down to win in the 14-year history of the Iowa tournament. Defending champion Russ Cochran had the days worst round, shooting a 6-over 78.
