Roger Federer got his ATP World Tour Finals campaign back on track with a straight-sets win over Richard Gasquet.
The Swiss star won 6-4 6-3 and will play Juan Martin Del Potro in his final Group B match on Saturday, with a semi-final place still up for grabs.
Federer, who lost to Novak Djokovic on Tuesday, needed six match points to see off Gasquet in a tense finish.
World number two Djokovic beat Del Potro in the evening session to secure his place in the semi-finals.
Federer, 32, is playing in the season finale for the 12th consecutive year and has only once failed to make it out of the group stage, but that danger loomed large after his defeat by Djokovic.
It remains a considerable task for the six-time champion to progress, with Del Potro likely to pose a sterner test than Gasquet.
“It is a big win for me and hopefully I can keep it up in the next match against Juan Martin,” said Federer. “There is a lot to play for. There are a lot of calculations going on in a three-way race, so hopefully it won’t be that close this time.”
