Zverev still waiting to put best foot forward

NEW YORK - It seems fair to conclude that No 4-seeded Alexander Zverev found his 3-6, 7-5, 7-6 (1), 7-6 (4) upset loss to Borna Coric in the US Open's second round on Wednesday night rather, well, upsetting.

"Today was upsetting," Zverev said. "The way I played was upsetting. The tournament so far is very upsetting for me."

The 20-year-old German is the highest-ranked man to exit Flushing Meadows so far and what bothered him so much wasn't merely that he didn't play well, but that there was a real opportunity for him to have a true Grand Slam breakthrough.
