Tommy Paul, the No. 1 boys’ seed in the USTA 12-under National Open tennis tournament, lost the first two games of his semifinal match Tuesday morning and was a point away from being down 3-0.

On a day of one-sided semifinals at the Champions Club, that was as suspenseful as Paul’s match got. Paul not only fought off the game point against No. 3 seed Anudeep Kodali, but he won 12 straight games for a 6-2, 6-0 win.

“I tried to keep patient, and when I got the chance I went for it,” said Paul, a Greenville, N.C., resident who is ranked No. 4 in the nation.

Paul lost in the third round here a year ago and said his game has come a long way since then. An aggressive, hard-hitting shotmaker, he produced winner after winner in the final 12 games. He hit backhands up the line and running cross-court forehands, he fired a few aces and he drove an overhead into the open court on match point.

“I think I’ve kind of grown into my game a little bit and have really worked hard to get better,” he said.

Awaiting Paul in the final is David Beasley, the No. 2 seed who is ranked No. 34 in the country. Beasley, from Greenwood, Ind., had a difficult first set Tuesday against 9 seed Adam Rudowski from Franklin, Tenn., before taking command and winning 6-4, 6-1.

Trailing 4-3 in the first set, Beasley broke Rudowski’s serve and went up 5-4 after chasing down a drop shot and driving a winner up the line on game point. He hit a cross-court backhand winner to close out the first set in the next game and was never threatened in the second set.

“I didn’t make as many mistakes in the second set,” Beasley said.

In the girls’ semis, Vooha Vellanki or Norcross, Ga., blanked fellow 5 seed Alexa Corse 6-0, 6-0 and No. 2 seed Diana Kussainova of Windermere, Fla., defeated Tiffany Huber 6-1, 6-4. Kussainova is ranked No. 18 in the country, while Vellanki is No. 40.

The boys’ and girls’ finals are today at 9 a.m.

While the singles might not have had much drama, there was plenty in Tuesday afternoon’s girls’ doubles final. The No. 2-seeded team of Georgians Clare Raley and Shelby King rallied from a 7-3 deficit to edge the top-seeded tandem of Sofia Kenin and Kussainova 9-7 in a pro set that lasted nearly two hours.

In the boys’ doubles final, the fourth-seeded team of Kodali and Michael Apple defeated second-seeded Lee Martin and Sebastian Bromley 8-5.
