Andy Murray emphatically ended American Donald Young's breakthrough run at the U.S. Open.

The fourth-ranked Brit won 6-2, 6-3, 6-3 Thursday to reach the quarterfinals for the first time since 2008. The match was supposed to begin Tuesday, but the players only got in three games Wednesday before rain postponed play again.

The 22-year-old Young was in his first Grand Slam round of 16, upsetting 14th-seeded Stanislas Wawrinka and 24th-seeded Juan Ignacio Chela along the way. A former top junior player who had struggled to live up to high expectations, Young is projected to reach a career-high ranking of around 56th.

Murray quickly took control Thursday, as Young had 53 unforced errors. Murray made his first Grand Slam final at Flushing Meadows three years ago, the only time he previously advanced past the fourth round at the Open.
