Melbourne, Australia (SportsNetwork. wholesale jerseys china .com) - Serena Williams quest for an 18th career singles Grand Slam title will have to wait a few more months. The world No. 1 will have to start a new winning streak too. Serbian Ana Ivanovic stunned Williams, 4-6, 6-3, 6-3 Sunday to reach the quarterfinals of the Australian Open. The 14th-seeded Ivanovic ended Williams 25-match winning streak and dealt the American a shocking fourth-round exit. Ivanovic, who was the runner-up in Melbourne in 2008 and was the French Open champion later that year, took advantage of 31 unforced errors from Williams. "Its not easy playing such a champion and Ive never beaten her before," Ivanovic said during an on-court postmatch interview. Before this match, Ivanovic had lost all four previous matchups against Williams. In fact, she hadnt taken a set against her, but that all changed at Rod Laver Arena. A five-time Australian Open champion, Williams lost for just the second time in 53 matches at the event when winning the first set. Her only previous defeat came last year in the quarterfinals to Sloane Stephens. Williams fought back from a break down to win the first set, but in the second Ivanovic broke for a 3-2 edge. She finally finished off the set on her third chance, a forehand winner. "I had some confidence coming into todays match," Ivanovic said. "I really did certain things extremely well, you know, and I kept her under pressure I felt throughout the whole match." The errors then started to pile up for Williams, as she lost the first three games of the final set. Williams held serve to get within 5-3 and saved one match point when Ivanovic sent a forehand into the net. The encounter finally ended when Williams sent a return long. "I wasnt the best, but it was all Anas day. I thought she played really well," said Williams, who fired 13 aces. "I made a tremendous amount of errors. Im just not used to missing those shots." Williams has been dealing with a back injury, which she termed as not "life threatening" but said she was unable to get additional days off due to the schedule of playing essentially every other day as a Grand Slam tournament requires. She even contemplated not taking the court Sunday due to the injury, but gave Ivanovic all the credit for winning. "I think its almost good I lost today because now I know what I have to work on," added Williams, who pulled out of the doubles competition with her sister, Venus before their first-round match. That was because Venus had a lower left leg injury. Ivanovic will face either 30th seeded Canadian Eugenie Bouchard or Australian Casey Dellacqua in the quarterfinals. Only three players have won 18 Grand Slam singles titles in the Open Era - Chris Evert (18), Martina Navratilova (18) and Steffi Graf (22). Serenas next chance at No. 18 will come at the French Open at the end of May. Fourth seed Li Na of China bested 22nd-seeded Russian Ekaterina Makarova, 6-2, 6-0 in 59 minutes. Li, who lost to Victoria Azarenka in last years finale in Melbourne, will face Italian Flavia Pennetta in the quarterfinals. The 28th-seeded Pennetta, who did not play the 2013 Australian Open due to a wrist injury. upended No. 9 seed Angelique Kerber of Germany, 6-1, 4-6, 7-5. This is Pennettas first quarterfinal appearance at the Aussie Open, but her second straight such showing in a Grand Slam tournament. Pennetta, who fired eight aces, was ousted by Azarenka at the 2013 US Open semifinals. Since 1999, only one German player has advanced to the Australian Open quarterfinals. That was Andrea Petkovic in 2011. fake jerseys china . Vinci also beat Dulgheru last week in Bucharest en route to her first WTA final in a year. Vinci next faces sixth-seeded Kurumi Nara of Japan, who beat Czech qualifier Katerina Siniakova 7-6 (5), 6-7 (3), 6-2. No. china jerseys . Not bad for a defenceman. The goal, that is. Although the shuffling dance steps werent bad, either. Barrie scored 55 seconds into overtime, Semyon Varlamov stopped 29 shots, and the Avalanche moved a step closer to their first playoff berth in four years with a 3-2 win over the Vancouver Canucks on Thursday night.SANTA CLARA, Calif. -- Down big, Jay Cutler kept his poise on the road while Colin Kaepernick struggled in prime time. Cutler passed for three fourth-quarter touchdowns after much of Chicagos starting defence went down, and the Bears beat the San Francisco 49ers 28-20 Sunday night to spoil their Levis Stadium debut. Cutler threw three TD passes to Brandon Marshall, two in the wild fourth quarter, as Chicago erased a 13-point deficit and quieted the sellout crowd. Cutler threw for two scores in a 27-second span early in the final period, aided by the gutsy play of a backup cornerback. Kyle Fuller made two late interceptions for the depleted Chicago secondary, and the first set up the go-ahead score. Kaepernick was hit with an unsportsmanlike conduct penalty for "inappropriate language" following Fullers first big play. That gave the Bears first-and-goal on the 3, and Cutler threw a 3-yard TD pass to Martellus Bennett as the Bears went ahead 21-20. Kaepernick threw three interceptions in all, lost a fumble and his cool, a far cry from his breakout start on the Monday night stage nearly two years ago in a rout of the Bears. Cutler sat out that night with a concussion. A sloppy game filled with 26 penalties -- 16 by the Niners -- and a crazy collapse overshadowed the fanfare of the regular-season debut for the sparkling $1.2 billion stadium. The Bears (1-1), in a stretch with six of eight games on the road, go home with some serious momentum despite injuries on both sides of the ball. Five key defenders are hurt: cornerbacks Sherrick McManis (quadriceps) and Charles Tillman (triceps), defensive end Trevor Scott (foot), safety Chris Conte (shoulder) and defensive tackle Jeremiah Ratliff (concussion). The 49ers (1-1) had a 17-7 halftime lead, but missed an opportunity to grab an early lead in the NFC West after the defendinng Super Bowl champion Seattle Seahawks lost earlier in the day at San Diego. cheap jerseys from china. Michael Crabtree caught a touchdown pass on his 27th birthday and Frank Gore ran for a score but also had his 54-yard TD burst negated by Anquan Boldins costly holding penalty. Cutler helped the Bears get on the board with a 25-yard run late in the first half. He took a jarring hit from Quinton Dial with 56 seconds remaining, but stayed in the game and threw a 17-yard touchdown pass to Marshall, who made a leaping, one-handed catch to pull the ball into his body as he fell into the end zone. What a way for Chicago to forget that bitter 23-20 overtime loss to the Bills at home in Week 1. San Francisco didnt give the ball away once in a season-opening win at Dallas. In the first half, the 49ers outgained Chicago 197-93 and out-penalized the Bears 10-7 for 85 lost yards. The much-scrutinized field featured visible chunks of loose sod after new grass was laid for a third time since April. Kaepernick made his first career start against the Bears nearly two years ago, and then held onto the No. 1 job over Alex Smith. Cutler didnt face the 49ers during a November 2012 Monday night game at Candlestick Park. A concussion to now-Chiefs QB Smith thrust Kaepernick into the spotlight that night, and he threw for 243 yards and two touchdowns as the Niners pounded the Bears 32-7. The 49ers were embarrassed at home for the second time in a month. They lost 34-0 in a rout by Denver in the first preseason game in the new stadium. Chicagos patchwork offensive line looked shaky early with centre Roberto Garza and left guard Matt Slauson each sidelined by ankle injuries. San Francisco tight ends Vance McDonald (knee) and Vernon Davis (ankle) were hurt as the 49ers lost a home opener for the first time under fourth-year coach Jim Harbaugh. ' ' '
