Isner tops Nieminen in 4 sets in US Open 2nd round

John Isner overcame a rare tiebreaker loss to advance at the U.S. Open with a second straight four-set win.

The top-ranked American man, Isner beat Jarkko Nieminen 6-3, 6-7 (5), 6-4, 6-3 in the second round Friday. The ninth-seeded Isner came in 37-13 in tiebreakers this year.

Isner was frustrated by a late let call he thought was incorrect that cost him a point while serving with a 5-4 lead in the second-set tiebreaker. Nieminen went on to win the last three points.

But Isner broke the 42nd-ranked Nieminen four times to reach the third round at the U.S. Open for the fourth straight year.

Isner had 23 aces, 69 winners and 44 unforced errors.
