Stan Wawrinka's shirt -- and game -- caught the eye Saturday at the Australian Open.

The Swiss star swept to victory over Lukas Rosol in straight sets. He later joked with the crowd that it would be impossible to miss him in such vibrant attire.

Wawrinka signs autographs after the match. The win was the 400th of his career.

The "Stanimal" will now face Milos Raonic of Canada in round four.

Raonic overcame Viktor Troicki Saturday 6-2 6-3 6-4.

Another contender for most colorfully dressed man at the Australian Open is John Isner. The big serving American defeated Feliciano Lopez of Spain Saturday to book his place in the next round.

Isner will face David Ferrer in round four after the Spaniard dispatched Steve Johnson 6-1 6-4 6-4.

There was a surprise in the women's draw as third seed Garbine Muguruza was defeated by Barbora Strycova of the Czech Republic 6-3 6-2.

Strycova will now face Victoria Azarenka who hasn't lost a set this year.
