NEW YORK (Reuters) -German Alexander Zverev got his bid for a maiden major off to a smooth start by beating American Sam Querrey 6-4 7-5 6-2 in the first round of the U.S. Open on Tuesday.

Querrey kept the match close through the first two sets but was stymied by unforced errors as 2020 runner-up Zverev kept his game comparatively clean and fired off 25 winners.
