Serena Williams loses 1st match since saying she's prepared to retire

Toronto: Serena Williams wore her game face when she stepped out into the stadium for her first match since telling the world she is ready to leave professional tennis.

Greeted by a standing ovation, the 23-time Grand Slam champion didn't smile. She didn't wave. She took a sip from a plastic bottle as she walked in.

Some folks in the crowd captured the moment with the cameras on their cellphones. Others held aloft handrawn signs oh, so many signs with messsages such as "Queen" or "Thank you."

No one knows exactly how many more matches Williams will play before she puts her rackets away for good, and the 40-year-old American exited the National Bank Open on Wednesday night with a 6-2, 6-4 loss to Belinda Bencic.

While there were some familiar fist pumps and yells of "Come on!" during competition, it was only afterward that Williams really allowed her feelings to show, her voice shaking and her eyes welling during an on-court interview when Bencic ceded the spotlight.

"A lot of emotions, obviously," Williams told spectators who offered her encouragement throughout the clear, 75-degree evening.

The second-round match at the hard-court tuneup for the U.S. Open came a day after she announced "the countdown has begun" on her playing career, saying she wants to have another child and pursue business interests.

She did not state precisely what her last event will be, but did make it sound as if her final farewell will come at the U.S. Open, which begins Aug. 29 in New York. AGENCIES
