Serena powers into another final

WIMBLEDON, England (AP):

Serena Williams defeated unseeded Petra Kvitova in straight sets yesterday to reach her third straight Wimbledon final and sixth overall.

The top-ranked Williams overcame a stiff challenge in the first set from the 62nd-ranked Czech player, then pulled away for a 7-6 (5), 6-2 victory.

Williams is now one win away from her fourth Wimbledon title and 13th Grand Slam championship.

She advanced to tomorrow's final against 21st-seeded Russian Vera Zvonareva, who rallied to beat Tsvetana Pironkova 3-6, 6-3, 6-2 in the day's first match on centre court and reached her first major title match.

It's the 10th time in the last 11 years that at least one of the Williams sisters has advanced to the final. Venus and Serena have won eight titles.

Serena has never beaten anyone other than her older sister in the championship match. Serena defeated Venus in the 2002, 2003 and 2009 finals.

Serena has a 12-3 record in Grand Slam finals and will be heavily favoured to beat Zvonareva. Williams has won five of their previous six matches.

"Vera's a great player who I had some unbelievable matches against, her so she's really tough," Williams said. "I feel like I have nothing to lose going into the final and she doesn't either, so it will be good."

Williams, who came into yesterday's match with a Wimbledon women's record of 73 aces, had only seven aces but came up with big serves when she needed them.

Wasn't easy

Kvitova, a left-hander playing in her first Grand Slam semi-final, went for broke and had more winners (24 to 19) than Williams but also more unforced errors (20 to 14).

"It definitely wasn't easy," Williams said after the 93-minute match. "I definitely had to work really hard. I didn't expect to get this far, the way I started at the beginning of the tournament.

"I just felt off, but I'm just happy to still be here. It's such a blessing to be able to still be in the tournament."

The 20-year-old Kvitova - who had lost in the first round in the previous two Wimbledons - pushed Williams to the limit in the first set, often controlling the play with her groundstrokes and pinning the champion behind the baseline.

Tiebreaker

Kvitova broke for 3-2, saved a break point in the next game and held to go up 4-2. But Williams broke back in the eighth game after Kvitova, holding a point for 5-3, missed three straight forehands to lose serve.

Williams went ahead 4-0 in the tiebreaker, let the lead slip to 4-3 and missed two set points before closing it out with a 115 mph (185 kph) service winner.

Williams was in command in the second set and broke twice. She finished the match with a backhand that hit the net cord and dropped over for a winner, then acknowledged the crowd with a wave and a small curtsy.

In the first match, Zvonareva came from a set down to beat the 82nd-ranked Bulgarian. The Russian was in complete command after breaking in the sixth game of the second set, winning 10 of the last 13 games.

Zvonareva has battled a reputation for fading in big matches but held her nerve on the biggest stage in tennis.
