Angelique Kerber takes her celebratory swim in the Yarra

MELBOURNE, Australia – In 1991, Australian Open champion Boris Becker celebrated his victory buy jumping in the river that runs right along the road lining the Australian Open grounds. The next two years champion Jim Courier and his coach took their own dives into the murky waters. It's been a tradition for champions ever since.

Some just stand along the river bank posing with their trophies. Angelique Kerber, who defeated Serena Williams in an major upset on Saturday night to win her first Grand Slam title, woke up Sunday morning and followed Becker's lead.

From there, the champion went on the traditional trophy tour of the neighboring Royal Botanical Gardens, where she posed for photos with her new hardware. Courier reportedly developed a stomach virus after his 1993 dive. Let's hope Kerber fares better.
