A ball boy briefly stole the limelight during last night's semifinal clash between Rafael Nadal and Roger Federer at the Australian Open with an impressive catch after Federer hit a ball in his direction.

The one-handed catch by the youngster happened at a tense moment in the third set with Federer serving to force a tie-break.

After serving a fault Federer sent a return from Nadal back towards the ball boy who stuck out his hand to pull off the catch, much to the appreciation of the Rod Laver Arena crowd who gave him a big cheer.
