Serena Williams’ return to the Western & Southern Open ended before it even started.

The two-time defending champion and World No. 1 withdrew from the tournament Monday due to a shoulder injury. Williams practiced at the Lindner Family Tennis Center in Mason in the morning and then made her decision.

“I’m very disappointed I’m not able to compete in the Western & Southern Open in Cincinnati, as I was really looking forward to defending my title,” Williams said. “My shoulder inflammation continues to be a challenge, but I am anxious to return to the court as soon as possible.”

The shoulder ailment also caused Williams to pull out of the Rogers Cup in Montreal last month.

Although Williams did not enter the W&S Open by a July deadline, she accepted a wild card last week after playing in the Olympics. Her stay in Rio was short, as she was stunned by Elina Svitolina in the third round of singles and with sister Venus bowed out of doubles in the first round.

Williams' exit has major implications at the W&S Open as it opens the door for a new No. 1. Second-ranked Angelique Kerber could dissolve Williams’ 183-consecutive-week stranglehold on the rankings’ top spot by winning the title.

The last time a player not named Williams was ranked No. 1 was in February of 2013, when Victoria Azarenka occupied the top spot. Williams has spent 306 career weeks atop the standings.

The 34-year-old American was replaced in the W&S Open's main draw by lucky loser Misaki Doi of Japan. Kerber will open the tournament after a first-round bye.

"While we were excited that Serena had accepted a wild card to play in the event, we understand that health is her number one priority. It will only contribute to her longevity and the chance for our fans to see her in Cincinnati for many more years," W&S Open tournament director Andre Silva said.

"We are very fortunate to have a field with WTA stars who now have an opportunity to win this title for the first time."

The turn of events is a contrast to the 2012 Olympics, where Williams won gold in singles and doubles. She then played her way into the W&S Open quarterfinals before being ousted by Kerber.

The news of Williams' withdrawal reached tennis fans quickly and was a disappointment to those like Kristena Bright of Woodlawn.

"I've never seen her play," Bright said. "I came here and I really wanted to see her. She's like my idol."
