NEW YORK - Novak Djokovic was bothered by his right arm during a first-round victory at the U.S. Open, getting treatment from a trainer, hitting slow serves and grimacing after some shots.
Still, the defending champion got through the match Monday night, beating Jerzy Janowicz of Poland 6-3, 5-7, 6-2, 6-1.
This was the No. 1-ranked Djokovic's first Grand Slam match since losing to Sam Querrey in the third round of Wimbledon.
Djokovic spoke before the U.S. Open about dealing with a left wrist injury that flared up in the days before the Rio Olympics this month. But it was his right arm that was problematic against Janowicz, a former top-20 player who reached the semifinals at Wimbledon in 2013 and is now ranked 247th after his own series of injury issues.
