NEW YORK — The latest on the U.S. Open (all times local):

Serena Williams got off to a rough start in her second-round U.S. Open match, before pulling out the opening set in a tiebreaker against Kiki Bertens, a qualifier from the Netherlands ranked 110th.
Williams, bidding for tennis' first true Grand Slam since Steffi Graf in 1988, got broken by Bertens to trail 2-1, then was down 5-4. But with Bertens serving for the opening set, Williams earned her first break point of the match and converted it.
Then in the tiebreaker, Williams fell behind 4-0, only to turn things around to grab that first set 7-6 (5).
