Williams' Coach Comments on Knee Injury's Impact on Loss

Friday, Sept. 9

"Since the start, it was terrible," Williams' coach Patrick Mouratoglou said, per ESPN's Greg Garber. "She was slow, very, very slow. Much slower than usual."

"At the end she tried to go for the winner on every shot," Mouratoglou added. "This with an injury. Even if she wins the second [set], it's not the point; she's not going to win the third. She cannot move. There is no match."

For a normal player, Williams' 2016 season would be one of great success. She has two singles titles, including a win at Wimbledon, and reached the finals at the Australian Open and French Open. 

Since Williams is an anomaly who can seemingly win at will, only having two tournament wins this season is a disappointment. She has battled physical problems along the way, including a shoulder injury that forced her to withdraw from the Rogers Cup and Western & Southern Open. 

Williams turns 35 in September, an age tennis players are lucky to be competitive in matches, let alone still ranked in the top two in the world. She has to carefully manage her schedule to avoid overextending herself and continue playing at a high level for another year or two.
