• Steve Tignor highlights an overlooked part of Williams' game.
For her part, Sloane [Stephens] is one of the few players who can match Serena’s pace and make her play defense on a regular basis. Stephens rifled forehand winners that thrilled the crowd, which was mostly behind her. When she had time to set up for that shot, she went for it and was lethal with it. In the first set, when she was able to match Serena’s intensity and shot-making, you got an idea of just good Sloane could be.
In the end, though, Sloane’s offensive firepower only highlighted how underrated Serena’s defense is. Few players make Serena scramble the way Sloane did today, but scramble she did. She forced Stephens to hit one more ball to finish rallies, and she returned serves that would have been aces against almost anyone else. The effort needed to win points eventually caught up with Sloane, who lost her early intensity in the second set and finished with 29 errors. For all of the bullets she hit, she only finished with 15 winners, a testament to Serena’s court coverage.
• Stephens' coach, David Nainkin, is pleased with her growth over the last year.
"She's a different player," her coach, David Nainkin, said. "You can see it. I was actually thinking early in the match of when she lost to Ana Ivanovic last year, reflecting on how she's improved as a tennis player and a person. She's really come a long way."
