Williams on fire at U.S. Open

NEW YORK (AP) — When her work was done, her first trip to the U.S. Open semifinals since 2010 secured, if just barely, Venus Williams sat in her sideline chair and beamed .

Williams reached her third major semifinal of the season — something she last did 15 years ago — by edging two-time Wimbledon champion Petra Kvitova 6-3, 3-6, 76 (2) on Tuesday night to a soundtrack of thunderous partisan support under a closed roof at Arthur Ashe Stadium.

“Definitely felt like a special match. No easy moments, not easy to hold serve or break serve,” Williams said. “This match meant a lot to me, obviously, playing at home and, of course, it being a major.”

The 37-year-old Williams, who won titles at Flushing Meadows way back in 2000 and 2001, trailed 3-1 in the third set before digging out of the hole with a little help: Kvitova’s eighth double-fault handed over the break that made it 3-all.

And Kvitova’s ninth double-fault got Williams to match point in the tiebreaker.

In the men’s quarterfinals, 12th-seeded Pablo Carreno Busta of Spain had no trouble beating No. 29 Diego Schwartzman of Argentina 6-4, 6-4, 6-2. It was Carreno Busta’s first match of the tournament against an opponent who was not a qualifier.

Carreno Busta’s debut in a Grand Slam semifinal will come Friday against No. 17 Sam Querrey of the U.S. or No. 28 Kevin Anderson of South Africa.
