World No. 1 superstar Novak Djokovic was an easy opening-round winner Tuesday at The Championships, Wimbledon.

The reigning Australian Open champion and U.S. Open runner-up handled capable German Florian Mayer in 6-3, 7-5, 6-4 fashion on Centre Court at the storied All England Club. The 6-foot-5 Mayer was a Wimbledon quarterfinalist last year, and in 2004.

"It was a big pleasure again performing here on Centre Court in front of the packed crowd," Djokovic said. "For the first round, it was tricky. I think Mayer's game is really well suited for grass, so it took a lot of effort."

The six-time Grand Slam champion from Serbia Djokovic captured his lone Wimbledon title two years ago.

Djokovic was joined in the round of 64 by eighth-seeded former U.S. Open champion Juan Martin del Potro, who dismissed Spaniard Albert Ramos 6-2, 7-5, 6-1. The 6-foot-6 Argentine beat Djokovic in last year's Olympic bronze-medal match on the grass courts here at the All England Club.
