WIMBLEDON (AP) Roger Federer is back at No. 1.

Federer has returned to the top of the ATP rankings on Monday, a day after winning Wimbledon by edging Andy Roddick 16-14 in the longest fifth set in Grand Slam final history.

Federer moves up from No. 2, switching places with former No. 1 Rafael Nadal.

A year ago at Wimbledon, Nadal beat Federer in the final and overtook him atop the rankings in August. That ended Federer's record stay of 237 consecutive weeks at No. 1.

Nadal did not defend his Wimbledon title, citing sore knees.

Sunday's title was Federer's sixth at Wimbledon and record-breaking 15th major overall.

The rest of the top 10 was mostly unchanged, with Roddick remaining at No. 6.
