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.
Roddick asked the line judge which foot crossed the baseline, and she told him it was his right foot.
''That's impossible,'' Roddick snapped.
He continued berating the official between points, making a joke about ''1-800-Rent-a-Ref.''
A TV replay showed Roddick did commit a foot fault - but with his left foot.
The lineswoman was not on court at the start of the fourth set.
