(Updates with Murray's win)


Scotland's Andy Murray rallied from a set down to defeat Poland's Jerzy Janowicz 6-7 (2-7), 6-4, 6-4, 6-3 Friday in the Wimbledon men's semifinals, advancing to his second straight final at the All England Club and moving one step closer to becoming the first British men's singles champion at this prestigious event in 77 years.

His victory earned him a spot in the final against Serbian world No. 1 Novak Djokovic, who won an epic five-setter against Argentina's Juan Martin del Potro earlier Friday 7-5, 4-6, 7-6 (7-2), 6-7 (6-8), 6-3.

The second-ranked Murray, who had come from two sets down to defeat Spain's Fernando Verdasco in Wednesday's quarterfinals, dug himself another hole on Centre Court against the big-serving Janowicz by losing the first set with some careless play in the tiebreaker.

The Scotsman was able to right the ship quickly, however, breaking the Pole's serve in the opening game of the second set and drawing even at a set apiece a few service holds later.

Murray lost his serve for the only time in the match early in the third set to give Janowicz some life, but he quickly seized back the momentum against his inexperienced opponent and never looked back.

Earlier Friday, Djokovic overcame Del Potro in the longest men's singles semifinal in Wimbledon history, finally pulling away at the end of the fifth set to win in four hours and 43 minutes.

Del Potro played the match with a heavily wrapped left knee but he managed to keep the match close thanks to some clutch play and Djokovic's inability to convert numerous break-point opportunities.

The Serbian won the 2011 Wimbledon title with a four-set victory over Spain's Rafael Nadal in the final, while Murray lost last year's final - also in four sets - to Switzerland's Roger Federer.

Sunday's showdown will be the fourth Grand Slam championship match between the two 26-year-olds.

The Serbian has defeated the Brit twice in the final of the Australian Open (2011 and 2013), while Murray won his lone Slam title with a five-set victory over Djokovic at the 2012 U.S. Open.

By reaching the final, Murray and Djokovic restored order to a wild and wacky Wimbledon that saw Federer, a seven-time champion, and Nadal, a two-time champ and five-time finalist, lose in the second round and first round, respectively.

Murray is trying to become the first British man to win the Wimbledon singles title since Fred Perry in 1936. EFE
