The wait for Serena and Venus Williams to play each other in a WTA event was four years. The match on Saturday didn't even last an hour.

Serena got the better of her older sister in the semifinals of the Family Circle Cup with a 6-1, 6-2 rout. It was the most lopsided result in 24 matches between the two siblings.

The Williams sisters had not played since 2009 in the final at the WTA Championships in Qatar. Serena posted a 6-2, 7-6 (7-4) victory in that contest and Saturday's triumph gave her a five-match winning streak in the series that dates back to 1998. Serena now owns a 14-10 mark against Venus.

Serena will meet Jelena Jankovic in Sunday's final. The ninth-seeded Serbian fought past Switzerland's Stefanie Voegele 6-4, 6-7 (6-8), 6-2.

The top-seeded Serena will be trying for her second straight Charleston crown and third overall, having first won on the green clay in 2008.

The American superstar will enter Sunday's final riding a 10-match winning streak and gunning for her third title of 2013. She won in Miami last week and also captured the season-opener in Brisbane.

Serena took command early Saturday, thanks to a few mistakes from her sister. Venus double-faulted on break point to give Serena a 2-0 lead in the first set and a couple of errors in the fourth game set up another break point, which Serena converted with a backhand pass for 4-0.

Venus rebounded with a forehand winner to break serve in the next game, but a double fault set up another break for Serena and she blitzed a second serve with a forehand winner for a 5-1 advantage. Serena then held at love to close out the first set in a mere 22 minutes.

Serena didn't commit her first unforced error until early in the second set, but she quickly broke serve in the first game and never relinquished her own serve the rest of the way.

Another break made it 5-2 and Serena held easily in the final game to finish the match in a tidy 54 minutes.

Prior to Saturday, the most lopsided score between the two was Serena's 6-2, 6-2 win in the 2002 Miami semifinals.

Both had to win a pair of matches on Friday after Thursday's action was delayed by rain.

The extra strain may have hurt Venus, who has an ongoing battle with Sjogren's Syndrome -- an auto-immune disorder that results in fatigue. The 2004 Charleston champ looked a bit ragged on Saturday and committed eight double faults without an ace. She converted just 52 percent of her first serves and won just 30 of the 82 total points played.

Serena is 5-4 against Jankovic, including a 6-3, 6-1 rout in the first round of last year's Olympics. The only meeting on clay, however, went to Jankovic in the 2010 Rome semifinals.

The winner of this $795,000 tournament will earn $125,000.
