NEW YORK (Reuters) - Alexander Zverev battled into the early hours of Tuesday to defeat a surprisingly troublesome Darian King 7-6(9) 7-5 6-4 at the U.S. Open. Dressed in knee-high socks and striped headband that recalled a 1970's-era Bjorn Borg, Zverev looked out of synch early in the match, the booming serve that helped bring him five titles this year lacking its usual punch. The German was uncharacteristically wasteful in a one hour, 21 minute first set, committing 31 unforced errors, before going on to draw first blood. "Obviously Darian came out playing really good tennis and I couldn't find my rhythm," he said on court after he finished the nearly three hour match with an overhead smash. Next up for Zverev is fellow 20-year-old Borna Coric of Croatia.
