NEW YORK (Reuters) - Defending champion Marin Cilic powered his way into the third round of the U.S. Open with a 6-2 6-3 7-5 victory over Russian Evgeny Donskoy in Flushing Meadows on Wednesday.
The ninth-seeded Croatian cracked 19 aces past the 139th-ranked Donskoy and clinched the second-round match with another huge serve that clattered off the Russian's racquet.
