You cannot be serious...the ball was in!
On of the innovations I've noticed at the Aust Open this year has been the Hawkeye system which tracks a ball's trajectory and can be used to show line calls. It was also been used here for the last couple of years for cricket decisions...especially LBWs.

Apparently its owned by a British company and is now used in tennis, cricket, snooker and baseball. I can easily see it taking over all ball sports.
