WIMBLEDON, England(AP) The roof over Centre Court at Wimbledon is being closed for the first time at this year's tournament - not because of rain, but because of fading sunlight.

The retractable cover, first used in 2009, is closing after the third set of No. 3-seeded Novak Djokovic's first-round match against Olivier Rochus of Belgium on Monday.

Rochus leads 6-4, 2-6, 6-3.

It's the third match on Centre Court during Day 1 of the tournament.
