Andy Roddick has advanced to the quarterfinals of the Australian Open after beating Fernando Gonzalez of Chile 6-3, 3-6, 4-6, 7-5, 6-2.

Gonzalez saved four set points in the 10th game of the fourth set on Sunday, then Roddick finally prevailed in the 12th game on a contentious call. A line umpire initially ruled that the ball had gone out, and Gonzalez claimed he had stopped when he heard the call.

Roddick asked for a video replay, which showed the ball hit the line, and Roddick won the point and the fourth set, levelling the match. Gonzalez complained to chair umpire Enric Molina of Spain, then kicked two drink bottles near the player’s chair.

Roddick, who won on his third match point when Gonzalez double-faulted, will next play Marin Cilic, who beat U.S. Open champion Juan Martin del Potro of Argentina 5-7, 6-4, 7-5, 5-7, 6-3.
