Garcia played well - she put together a +10 differential of winners to unforced errors (15 to 5) and traded big serves and huge groundstrokes throughout the match. But the No.1-seeded Williams was on another level, putting together a +21 differential (30 to 9) and never even facing a break point. At the end of the day Williams needed just 67 minutes to send the French teenager home, 63 62.
"I still feel like I'm trying to adjust a lot," Williams said in her post-match presser. "I feel like today I played a little better than my first round match. I feel like I had to play better. But I'm still adjusting."
It was a bit of déjà vu for Garcia - she lost to Williams in the same round of the French Open.
"It's always difficult to play Serena, but I played much better today than I did at the French Open, because I knew her a little bit better," Garcia said afterwards. "It was nice to play her on Court 1 here. It's a very nice court. The fans there really like their tennis, so it was a good experience."
Williams extended her winning streak to 33 matches, now the standalone second-longest winning streak of the new millennium, breaking a tie with Justine Henin's 32-match winning streak across the 2007 and 2008 seasons. Venus Williams still has the longest, winning 35 matches in a row in 2000.
Awaiting Williams in the next round is Kimiko Date-Krumm, who beat Alexandra Cadantu earlier in the day, 64 75. The 42-year-old Japanese made history with the win, becoming the oldest woman to reach the third round of Wimbledon in the Open Era - she is also the second-oldest woman to reach the third round of any Grand Slam in the Open Era, after a 45-year-old Renee Richards at the 1979 US Open.
"I'm very happy to be in the third round, especially since I love Wimbledon and have many good memories here," Date-Krumm said in her presser. "I think it's amazing. I cannot believe it. But this year I skipped a lot of the clay court season so I could focus on the grass. And luckily this year I didn't play a seeded player in the first round, because most of the time I did. It's working. I'm very happy."
Williams and Date-Krumm will be playing against each other for the first time.
"I have so much respect for her," Williams said. "I think she's so inspiring to be playing such high level tennis at her age. And she's a real danger on grass courts - I know that - I will have to be ready."
And on her game? "Kimiko has great hand-eye coordination," Williams said. "Doesn't matter how hard you hit it, she sees the ball and gets it back. She has great hands, a wonderful great volley, comes to net a lot, which on grass can be tricky. And she plays really flat too, so the ball stays really low.
"I saw her match with Venus a few years ago. I think I lost four years of my life watching that match. So I will definitely be talking to Venus and figuring out what I can do to do the best I can in that one."
Date-Krumm was equally impressed with Williams. "She's so strong. It's very, very difficult to beat her," she said. "I played with Venus here two years ago, and this year in Miami, but of course there's a big difference between Venus and Serena. Serena has more power and more speed. She has more confidence. She has more everything. I just need to try my best on the court and we'll see.
"I hope I can stay on the court more than an hour, an hour and a half."
