Sir Ben Ainslie bounced back with a much-needed victory in an America's Cup race that pitched four British Olympic champions against each other.
Ainslie and Rio gold medallist Giles Scott knew they needed a win for British boat Land Rover BAR after four consecutive defeats in Bermuda.
And they duly got the better of Sweden's Artemis, whose crew includes Iain Percy and Paul Goodison - with three Olympic golds between them.
Ainslie's team have won both their races against Sweden in the qualifier series, from which only four of five boats will progress to the challenger play-offs.
And this victory moves them to third in the overall standings, thanks mainly to a two point head start after their victory in last year's America's Cup World Series.
"We really needed that one and the guys did a great job," said a clearly relieved Ainslie.
"After the disappointment of the last few days, we did lots of debriefing and we made some big changes to the boat.
"It was a big day for us because we knew we had to turn it around and we were able to improve the performance markably.
"Our speed was a lot better and we sailed a great race. Giles called some great tactics and that's a big boost for us but we need to keep developing and pushing forward."
Ainslie team faces another tough day's racing on Wednesday with match ups against New Zealand and France, two crews they lost to in their first encounters.
They will then get two invaluable days to practice and keep working on their boat before final qualifiers against Japan and defending champions Oracle Team USA on Saturday.
