Andy Roddick carried on a lengthy argument with a U.S. Open lineswoman over a foot-fault call Wednesday night -- although it wasn't nearly the sort of tirade Serena Williams delivered a year ago, nor did it come at as crucial a moment. The call was made while Roddick trailed in the third set of what would become a 3-6, 7-5, 6-3, 7-6 (4) loss to Janko Tipsarevic in the second round. http://sports.espn.go.com/sports/tennis/usopen10/news/story?id=5522101
