Camila Giorgi has pulled out a three-tiebreaker victory over Kaia Kanepi in the first round of the Miami Open.

With rain forcing many players to double up Friday in Washington, D.C., the quarterfinals—led by the Aussie-American clash—finally took shape.

Gauff won in straights when these two met on clay last year, but it could have gone either way. If the American is to prevail again, expect another close contest.
