Melbourne, Australia - Tomas Berdych fended off a David Ferrer comeback on Tuesday and reached his first Australian Open semifinal as a result. Berdych, seeded seventh, won the first two sets of the quarterfinal meeting in quick fashion, then suddenly lost the momentum when the third-seeded Ferrer rallied to win the third. The hard-hitting Czech, having lost in the quarters of the Aussie Open the previous three years, made sure it wouldnt happen a fourth as he finished off a 6-1, 6-4, 2-6, 6-4 triumph at Rod Laver Arena. The first set lasted just 30 minutes, and Berdych appeared poised to make it a quick one by taking a two sets to love lead. Ferrer broke Berdychs serve twice in a third set that saw him nudge a line judge standing near a chair he wanted to put a towel on, a sign he was up for a fight. The frustrated Spaniard, however, couldnt overcome Berdychs serve in the fourth, as Berdych fended off a break point in the final game and came away with the victory in three hours, three minutes. Ferrer rallied from two sets down to beat Nicolas Almagro in last years Aussie quarters before eventually losing in the semis to Novak Djokovic, who will play eighth-seeded Swiss Stanislas Wawrinka in Tuesdays other quarterfinal. The former No. 1 Djokovic is a dominant 15-2 lifetime against Wawrinka, including a fourth-round win here a year ago. The Serbian star also topped the Swiss in a U.S. Open semifinal last season. Djokovic, seeded second this year, has won his last 25 matches at the Aussie Open, where hes the three-time reigning champion and has captured four of the last six titles Down Under.

Playing in his 19th career final, the second-seeded Tsonga was favourite to win the Open 13 for the third time and to secure an 11th career title, but he struggled with Gulbis attacking approach.INDIANAPOLIS - The Indianapolis Colts have the top-ranked offence in the NFL, but theyre far from having it all figured out.The Colts offensive line is still without an identity, and that doesnt bode well for quarterback Andrew Luck, who leads the NFL in yards passing (1,305) and touchdown passes (13).During a fun back-and-forth with Baltimore coach and former colleague John Harbaugh this week, Colts coach Chuck Pagano didnt directly address who will start at centre against the Ravens (3-1). Former Raven A.Q. Shipley has started at centre for Indianapolis (2-2) this season.We have a lot of centres on our team, Pagano said. Weve got a bunch of guys in that room that are more than capable of playing a bunch of spots on that offensive line. We talk about position flexibility all the time and everybody has got ample reps at all the spots. Every man is ready to go.Shipley started nine games for the Ravens last season, giving him an edge in this weeks game plan and possibly an advantage for the starting job. Pagano will make that decision on Sunday.Its always great to have a guy on your team that has been with the team youre playing, Pagano said. There are a lot of things you get from tape and a lot of things you cant get from tape. Having a guy on your squad that knows those guys and can give you some of the intangibles that you cant get off film is a plus for us.Shipley echoed his coachs opinion.I definitely know (Baltimore). I went against them every day for a year and a half. Ive seen their defence, I know their tendencies and I know thhe moves of the (defensive) lineman, Shipley said.ddddddddddddBut if it isnt Shipley, what are the options for Indianapolis?Undrafted rookie Jonotthan Harrison has been getting snaps with the first team offence in practice with Shipley. During camp, Khaled Holmes was the projected starter but has not split reps. Shipley has prepared for this week the same as any other.Our job every week is to prepare like youre the starter. Thats his job, thats my job and were going about it the same way, Shipley said. Whether they call him or whether they call me, well both be ready and the other will be ready to back up. (Harrison) is a good player and hes doing a heck of a job.Centre isnt Indianapolis only concern. Because of Joe Reitzs ankle injury, rookie left guard Jack Mewhort started the first four games this season. But hell be out with his own ankle injury on Sunday. Veteran Lance Louis will start in his place.We just try to help each other as much as we can. Our O-line has a real good relationship, we gel together and share our experiences, Louis said. I pride myself on preparation. We know theyre a championship calibre team, its going to be a fight for four quarters and weve prepared for that way all week.Indianapolis search for identity on the offensive line will be tested Sunday by a playoff-calibre team and possible playoff opponent.You dont see (Ray Lewis) and (Ed Reed) but what you do see is a bunch of game-wreckers. Theyre an excellent defence, Pagano said. Just turn the tape on. Theyre relentless. Its in their DNA. ' ' '
