Federer lost to another player outside the top 100 (Sergiy Stakhovsky) in the very last tournament he played in, the 2013 Wimbledon championships, in the second round. Stakhovsky was ranked #116 at the time while Delbonis is ranked #114. Federer made news this week because he has traded in his old racquet with a relatively small head of 90 square inches for one that has 98 square inches. Most top-level tour players play with racquets with at least 100 square inches. It's not clear what impact the racquet had on his game, but he played two tough 3-set matches, against Daniel Brands and Florian Mayer, two good players, but not players whom a 17-time major champion would be expected to struggle against.
16-time champion Serena Williams is now 50-4 for 2013, the fastest she has ever won 50 matches in a calendar year. She will play in the final of the Swedish Open, where she will face hometown favorite Johanna Larsson.
