Andy Roddick won the vital fourth set of his 6-3, 3-6, 4-6, 7-5, 6-2 win over Fernando Goznalez at the Australian Open after overturning an out call with a successful HawkEye challenge. The point was awarded to Roddick, but Gonzalez argued that it should have been replayed because he would have returned the shot if it had been called in.
Roddick was on the other end of a similar situation at match poit in his third-round match earlier in the week, arguing that the point should have been replayed instead of awarded to his opponent because Roddick had had a play on the ball.
The decision to award the point or replay it after a HawkEye overrule is at the umpire's discretion, based on a judgment about whether the rally would have continued if there had been no call from the linesman.
