LONDON — Stan Wawrinka grabbed the last semifinal spot at the ATP World Tour finals by beating Andy Murray 7-6 (4), 6-4 Friday in the last group-stage match at the season-ending tournament.

Murray led 4-2 in the first-set tiebreaker but then lost the next five points and was broken in the first game of the second to put Wawrinka in control. The French Open champion broke again for a 5-2 lead but needed two attempts to serve out the match. He saved two break points at 5-4 before converting his second match point when Murray’s backhand went wide.

Wawrinka will play Swiss compatriot Roger Federer on Saturday, while Rafael Nadal faces Novak Djokovic in the other semifinal. Nadal beat David Ferrer 6-7 (2), 6-3, 6-4 earlier to finish the group stage unbeaten.
