Flushing Meadows, NY - Top seed Novak Djokovic beat Argentinas Diego Schwartzman in three sets Monday night in their first-round match at the U.S. Open. Djokovic started his quest for an eighth Grand Slam title with a 6-1, 6-2, 6-4 win in the final match of the night at Arthur Ashe Stadium. The Wimbledon champion Djokovic has a run of four straight finals at the Open, including a championship in 2011 against Rafael Nadal. Djokovic lost last year to Nadal, but the Spaniard isnt defending his title this year due to a right wrist injury. Playing his first career tour-level main draw match on hard courts, the 22- year-old Schwartzman was no match for the worlds No. 1 player. The Serbian breezed through the first two sets in 56 minutes. Schwartzman won the first game of the third set and then had a chance to break, but a smiling Djokovic roared back and evened the set with an ace. There were a couple of hiccups from Djokovic, as Schwartzman broke to tie it at 3-3, but he couldnt follow it up. Djokovic broke back and then held at love before closing it out. "Its never easy to start a U.S. Open smoothly," said Djokovic, who had 27 unforced errors, three more than Schwartzman. Up next for Djokovic will be Frenchman Paul-Henri Mathieu, who topped Gilles Muller of Luxembourg in a five-set marathon. "Im sure well both be fresh and motivated to play," Djokovic said. "Hes a very solid player from the baseline, but Ill focus on myself and hope to do as well as I did tonight." Former champion Andy Murray was tested in his first-round match Monday, while third seed Stan Wawrinka and No. 5 seed Milos Raonic won their openers in straight sets. Murray, the eighth seed and former world No. 2 star, battled cramps before holding off wily Dutchman Robin Haase 6-3, 7-6 (8-6), 1-6, 7-5 in 3 hours, 8 minutes. "I dont know what it was. I was cramping after 1 hour and 45 minutes," Murray said. "I didnt know what to do in the third set. I started to get it in my laterals and forearms when I was serving. I didnt know whether to conserve energy or try to finish it. "I tried to hang around and tried to play without using my legs much. I managed to get through. These slams are physically challenging, but I need to work out why it happened. It shouldnt have happened, regardless of the temperature." Murray overcame a 1-4 deficit in the fourth set to get off the court before a fifth. The two-time Grand Slam champion was the U.S. Open winner two years ago and runner-up in Flushing in 2008. His second-round opponent will be German Matthias Bachinger. Wawrinka, this years Australian Open champion, topped Czech Jiri Vesely, 6-2, 7-6 (8-6), 7-6 (7-3). Wawrinka, who is from Switzerland, reached his first U.S. Open semifinal last year before losing to Djokovic. The Canadian Raonic eased past Japans Taro Daniel, 6-3, 6-2, 7-6 (7-1). Raonic, who has reached the fourth round here the last two years, is trying to build on a semifinal appearance at Wimbledon when he lost to Roger Federer. Ninth-seeded former Australian Open runner-up Jo-Wilfried Tsonga of France snuck past gritty Argentine Juan Monaco 6-3, 4-6, 7-6 (7-2), 6-1. In other opening-day action involving seeds, No. 16 Tommy Robredo of Spain defeated Frenchman Edouard Roger-Vasselin, 6-4, 6-3, 6-4; promising Aussie Nick Kyrgios upended No. 21 Russian and two-time U.S. Open semifinalist Mikhail Youzhny 7-5, 7-6 (7-4), 2-6, 7-6 (7-1); No. 22 German Philipp Kohlschreiber handled Argentine Facundo Bagnis 6-2, 7-6 (7-3), 6-3; No. 23 Argentine Leonardo Mayer was leading Albert Montanes 6-2, 3-0 when the Spaniard retired; Benoit Paire took out No. 24 fellow Frenchman Julien Benneteau 7-6 (7-4), 5-7, 6-4, 4-6, 6-4; 30th seed Jeremy Chardy of France toppled Colombian Alejandro Falla, 6-7 (5-7), 6-2, 7-5, 6-4; and No. 31 Spaniard Fernando Verdasco outlasted Slovenian Blaz Rola 6-3, 3-6, 7-5, 1-6, 6-4. Several other men moved on, including Italian players Andreas Seppi and Simone Bolelli.

Therrien would not confirm his lineup for the game, but he did have the same line combinations practicing together for the third straight day which is usually a pretty good indication of what the lineup will be.SAN FRANCISCO - Several of the San Francisco 49ers have said they are hopeful their new head coach is a lot like the old one, Jim Harbaugh.The players have expressed confidence in a couple of familiar faces in the building who could become San Franciscos new head coach.Whether CEO Jed York and general manager Trent Baalke decide to promote from within is the big question: Defensive co-ordinator Vic Fangio and defensive line coach Jim Tomsula are considered the best bets to be considered for promotions from the current coaching staff.Hes going to have to have pretty much everything that Jim Harbaugh had, tight end Vernon Davis said. Because he was good, he was really good.Fangio — who joined the 49ers with Harbaugh from Stanford in 2011 and led one of the NFLs top defences — interviewed last week. But theres been no confirmation that Tomsula has had a formal sit down with team executives, who are through their second week of a coaching search they initially said would likely last seven to 10 days.Weve just got to wait and see, left guard Mike Iupati said. Similar to Harbaugh, I really love Harbaugh. Whatever coach comes, I wish him the best of luck and see where he takes the team.If Fangio is hired, he is expected to consider Kyle Shanahan for his offensive co-ordinator after Shanahan parted ways with the Browns this week.I would like to see Vic Fangio here, linebacker NaVorro Bowman said. Whether thats head coach or (defensive co-ordinator), I would like to see him here.The Washington Redskins were denied permission to interview Fangio for their defensive co-ordinator vacancy, a person with knowledge of the request said Friday. The person spoke on condition of anonymity because those dealings between teams areent made public.ddddddddddddFangio adapted this past season with a new-look defence given the injuries of star linebackers Bowman and Patrick Willis, and the nine-game suspension of linebacker Aldon Smith to start the year.Fangio has worked for a number of NFL teams during his long career, from the Saints to the Panthers, Ravens, Colts and Texans.While the 49ers, who finished 8-8 and missed the playoffs for the first time in four years, need to fix plenty on the offensive side of the ball, they believe defensive coaches Fangio and Tomsula could make that happen with the right supporting cast around them.Were comfortable with those guys, left tackle Joe Staley said. I have a lot of respect for what they do. All that stuff is going to take care of itself.Other candidates who were at least considered and some of whom have interviewed: Seahawks defensive co-ordinator Dan Quinn, Denver offensive co-ordinator Adam Gase, former Raiders, Broncos and Redskins coach Mike Shanahan, Patriots offensive co-ordinator Josh McDaniels and Cardinals defensive co-ordinator Todd Bowles, who was scheduled to interview by weeks end.I really honestly dont think we need a full overhaul. I dont think we need to make drastic changes, Staley said. There are things we need to change as far as mentality, accountability, different things like that. But as far as an overall scheme and huge change, blowing up the place, that doesnt need to happen. Weve got the talent and the guys in the locker room to get it done.Also Friday, the Niners announced they have signed linebacker Shayne Skov to a reserve/future contract. He was part of the teams practice squad this year.___AP NFL website: www.pro32.ap.org and www.twitter.com/AP_NFL ' ' '
