That Andy Roddick's last match as a twentysomething would not be his last match at the 2012 U.S. Open was hardly in doubt Tuesday, especially whenever he was launching that intimidating, tough-to-handle serve of his. To close the first set: ace at 141 mph. To close the second: ace at 134 mph. To close the third: ace at 127 mph. Yes, even as Roddick's 30th birthday approaches on Thursday, even as his body has succumbed to injury after injury, that serve is pretty much still the same as it ever was. Now that he more frequently faces opponents who grew up cheering for him -- such as 21-year-old qualifier Rhyne Williams of Knoxville, Tenn., the foil for Tuesday's 6-3, 6-4, 6-4 victory -- Roddick knows more than ever he needs to rely on the best thing he's got, and 20 aces helped this time.
