    Serena Williams avenged her 2011 U.S. Open final defeat to Samantha Stosur with a straight-sets win over the Australian sixth seed to reach the last eight of the WTA tournament in Miami Monday.
    Williams went into the final at Flushing Meadows last year as a hot favorite to add to her tally of 13 grand titles, but was swept aside by a super-charged display from her opponent who was claiming her first.
    Neither has enjoyed much success since, with Stosur's form falling away and Williams sidelined by injuries.
    But the former world No. 1 is returning to her best at a hard-court tournament she has won five times, seeing off Stosur 7-5 6-3 in one hour 45 minutes in their last-16 match. The American converted four of 13 break-point opportunities to go 5-3 career against Stosur.
    The two-time Miami runner-up will next play Caroline Wozniacki, who beat Belgian 23rd seed Yanina Wickmayer 7-6 (8-6) 6-0.
