Cilic beats Berdych to reach US Open semi-finals

The 14th seed becomes the first Croatian since Goran Ivanisevic in 1996 to reach the final four at Flushing Meadows, and he pulled off the upset under the watchful eye of Ivanisevic, now his coach.
Cilic, who missed last year's US Open as he sat out a doping ban, pounded 19 aces past Berdych, recovering an early break in the third to force the decider.
He'll face either five-time champion Roger Federer or 20th-seeded Gael Monfils of France for a place in the championship match.
