Serena WilliamsWorld No. 1, Serena Williams of the USA, had a shaky start, but managed a straight-sets victory over Stefanie Voegele of Switzerland. No. 76 ranked Stefanie took the No. 1 seed to a tie-break in the 1st set, which Serena won 7-2. Serena then put the match away with a more convincing second set, 6-2.

Serena managed 28 winners with 22 unforced errors, while Stefanie hit 13 winners, but had only 12 errors. Serena reached break point against Stefanie only 3 times in the match, but converted on all three. Stefanie scored on only 1 of 4 break points she held against Serena.

Serena had more trouble than she should have against a 76 ranked player, and Serena seems to agree. She was not pleased with her performance. After the match, she said: “I definitely didn’t feel good about it. At least I won. I think I’m still in the tournament; that’s what matters.”

Serena will next play No. 81 ranked Julia Goerges in the 2nd round on Thursday.
