Novak Djokovic wears Darth Vader mask for Halloween match in Paris

Novak Djokovic sure is taking this No. 1 ranking business seriously. The Serbian, who will take over the top spot in the tennis world from Roger Federer on Monday, decided to show up as the ultimate villain for his match on Wednesday against Sam Querrey.

OK, so Djokovic actually wore the Darth Vader mask because the match was being played on Halloween -- he didn't actually wear the mask during the match -- but the decision to sport the mask of a villain seemed fitting considering he's played the villain role on numerous occasions in his career.

While the Vader mask was a first for Djokovic, it wasn't the first time he's worn a Halloween mask on the court. Just last year, he sported a Joker mask for his opening match in Basel before winning in three sets over Xavier Malisse.

This time around, however, his luck wearing masks on Halloween ran out, as Djokovic lost 0-6, 7-6 (5), 6-4 to Querry. Maybe next time around he should consider wearing the mask during the match to intimidate his opponent.
