PETERSBURG, Fla. (AP) — Serena Williams will miss the season-ending WTA Finals for the second year in a row, citing a right shoulder injury.

The WTA announced Williams’ withdrawal from the tournament a week before play begins next Sunday in Singapore, releasing a video from the 22-time Grand Slam singles champion.


Williams says she is “really, really bummed” to skip the event, but adds that her doctor “insists that I stay home and heal” her shoulder.

Adds the 35-year-old American: “It’s been a really tough year for me.”

She hasn’t played since losing to Karolina Pliskova in the U.S. Open semifinals in early September, a defeat that resulted in Williams ceding the No. 1 ranking to Angelique Kerber after a 3½-year stay at the top.

Williams played in only eight tournaments in 2016, winning two of them, including Wimbledon in July. [/restrict]
