Flushing Meadows, NY (Sports Network) - World No. 1 and four-time U.S. Open titlist Serena Williams straight-setted fellow American Sloane Stephens in fourth-round action Sunday at the U.S. Open. The reigning U.S. and French Open champ Williams, a 16-time Grand Slam winner, smashed six aces en route to a 6-4, 6-1 triumph over the 15th-seeded Stephens on the hardcourts at the USTA Billie Jean King National Tennis Center. "I definitely think it was a high quality match. I dont think either of us had an overwhelming amount of unforced errors," said Williams. Williams, who defeated Victoria Azarenka in last years outstanding final in Flushing, will take on Carla Suarez Navarro in the quarterfinals after the 18th-seeded Spaniard upended eighth-seeded Angelique Kerber of Germany by a 4-6, 6-3, 7-6 (7-3) margin.

The suspension is the second in two seasons for Browner. He was suspended four games last season for violating the leagues policy on performance-enhancing substances. Hes the second Seahawks player to be suspended for violating the substance abuse policy this season. Fellow cornerback Walter Thurmond is serving the final week of a four-game suspension. Browner, whose suspension is effective immediately and without pay, sent out a lengthy statement vowing that he would continue to fight his suspension and sounding resigned that his career with the Seahawks was over. "I want to thank the Seahawks organization for the incredible opportunity they gave me when they took a chance on a player who was out of the NFL and playing in the CFL for 4 years," Browner wrote. "I also want to thank all of my teammates, coaches, trainers, staff and the 12s (fans) for their support, respect, and friendship and for helping me grow into the player, father, and person I am today. I have been treated with nothing but first class by everyone associated with the Seattle Seahawks and for that I am forever grateful. "Although I disagree with the circumstances surrounding my suspension, I accept responsibility for all of my actions and I apologize for any that causes any unflattering reflections of my family and the Seahawks. I believe in my innocence and will continue to fight with all legal resources aavailable to me to.dddddddddddd." Browner, who was injured in Week 10 against Atlanta and hasnt played since, filed an appeal of the suspension while injured and the Seahawks were waiting for an answer from the league. Seattle coach Pete Carroll said earlier Wednesday before the suspension was announced that he was frustrated the process for making a determination on Browners status had taken so long. "It has taken a long time and Ive been a little disappointed in that, but were handling it," Carroll said. Browner is in his third season with the Seahawks. He started all 26 games he has played for the Seahawks and has 19 tackles, one interception and 10 passes defenced this season. He was a Pro Bowl selection in 2011 when he had 23 passes defenced and six interceptions, but had not been able to match those numbers in the subsequent two seasons. Browner was to become a free agent after the season and could file for reinstatement after one year. News of the suspensions for both Browner and Thurmond came as the Seahawks were returning from their bye in late November. Browner is the seventh official suspension for a Seattle player for substance-abuse or performance-enhancing drugs violations by the league since 2011. That doesnt include Richard Sherman, whose suspension was overturned on appeal late last season. The two suspensions have given chances to backups Byron Maxwell and Jeremy Lane. They have played well enough that it was not guaranteed Thurmond or Browner would get their starting spots back when they returned. ' ' '
