The Italian syndicate Luna Rossa is on track for a clean sweep of the America's Cup challenger series semi-finals, after another win over Swedish syndicate Artemis on San Francisco Bay.
For the second straight day Artemis led from the start and around the first mark, before Luna Rossa took control to win by just over two minutes.
The first to four wins will go on to meet Team New Zealand in the challenger series final.
The next scheduled race days are this weekend.
