LONDON (AP) -- Top-seed Novak Djokovic survived in the longest semifinal in Wimbledon history outlasting former US Open champ Juan Martin del Potro 7-5, 4-6, 7-6, 6-7, 6-3. Djokovic prevailed in the exhausting, high-quality four-hour, 43-minute marathon to reach his second Wimbledon final.
The eighth-seeded del Potro saved a pair of match points in the fourth set tiebreaker, but couldn't hold on in a battle that left both players visibly spent at the end.
Andy Murray keeps British hopes alive for the home country's first Wimbledon men's champ in 77 years. The second -seed reaches the Wimbledon final for the second straight year with a 6-7, 6-4, 6-4, 6-3 win over Poland's Jerzy Janowicz in the other semifinal.
