NEW YORK - Serena Williams eliminated No. 2 seed Anett Kontaveit 7-6 (4), 2-6, 6-2 in the U.S. Open’s second round Wednesday night to ensure that the 23-time Grand Slam champion will play at least one more singles match at what she’s hinted will be the last tournament of her illustrious career.

The 40-year-old Williams was again buoyed by a loud crowd at a full Arthur Ashe Stadium, just as she was in the first round two days earlier.

She hit serves at up to 119 mph, stayed with Kontaveit during lengthy exchanges of big swings from the baselines and conjured up some of her trademark brilliance when it was needed most.

The six-time champion at Flushing Meadows will play Friday for a spot in the fourth round. Her opponent will be Ajla Tomljanovic, a 29- year-old Australian.
