On one point Tuesday at Wimbledon, Serena Williams dumped a forehand into the net and dropped to a knee, her jaw clenched as she let out a shriek.
On another, she pushed a backhand into the net while her feet gave way, yet again leaving her awkwardly splayed on the grass at Court 2, the same place where her sister Venus lost a day earlier.
By the end, the younger Williams was screaming after nearly every point, good or bad - and, well, there were plenty of both. Her harder-than-the-score-looked 6-2, 6-4 victory over the 62nd-ranked Barbora Zahlavova Strycova of the Czech Republic in the first round at the All England Club wasn't exactly perfect or pretty.
"Definitely a little relief," the sixth-seeded Williams said. "I was letting out a lot of cries. I was happy to get through that."
Yes, Williams got the job done, something she couldn't say the last time she was at a major championship. Last month at the French Open, the 30-year-old American tossed away a big lead - nine times, she was two points from victory - and lost to a woman ranked 111th, the only first-round exit of Williams' career in 48 Grand Slam tournaments.
"I learned that you got to ... keep going," Williams said about that stunning defeat. "I was really disappointed. Obviously, I was extremely disappointed. But as Kelly Clarkson says, `What doesn't kill you makes you stronger."'
"For me, when I'm playing a match," Williams said, "I either win it or lose it."
She'll want to play better than she did against Zahlavova Strycova, who is 0-21 against top-10 opponents, 13-27 in Grand Slam matches, and never has made it past the third round at any major.
Some other top players were sluggish at the start against unheralded foes Tuesday, when action was cut short in the evening because of rain.
Defending women's champion Petra Kvitova fell behind 3-0 and 4-1 but eventually used a seven-game run to take control and beat 96th-ranked Akgul Amanmuradova 6-4, 6-4. The match was halted by a 30-minute rain delay in the second set; when they returned, Kvitova needed all of three minutes to wrap things up.
"In the beginning," Kvitova acknowledged, "I think I was nervous."
Twelve singles matches were suspended in progress and four were postponed altogether. Among those that began but didn't finish, 2003 U.S. Open champion and three-time Wimbledon runner-up Andy Roddick led British wild-card entry Jamie Baker by a set and a break; French Open finalist Sara Errani was a point from beating U.S. qualifier CoCo Vandeweghe; and 21st-seeded Milos Raonic of Canada was a game from eliminating Santiago Giraldo of Colombia, leading by two sets and 5-4 in the third.
