Thomas Stone High's Jewel Clark prepared for the basketball season by heading to the gym every morning last summer. With her younger brother Rodney in tow, Clark arrived at 7 a.m. and shot baskets for 2 1/2 hours.

It's as if Clark hasn't stopped shooting--and making--baskets since. Friday night, she tied her season-high with 28 points and led undefeated Thomas Stone to a 62-42 win over visiting Westlake in a Southern Maryland Athletic Conference doubleheader.

Thomas Stone's boys team completed a sweep of Westlake with a 75-73 victory. Harshod Spells scored nine of his team-high 22 points in the fourth quarter for the Cougars, and Anton Washington finished with 16 points as Thomas Stone (2-3, 2-0 SMAC) erased a 41-37 halftime deficit.

Westlake, the defending conference champion, fell to 0-4, 0-1.

In the girls game--the conference opener for both teams--Thomas Stone (5-0, 1-0) continued to look like a favorite to win the SMAC title. Westlake (1-3, 0-1) kept struggling after going 11-14 last season.

Clark, a 5-foot-11 senior forward, boosted her season scoring average to 22.3 points per game. She averaged 12 points per game as a freshman, 17 as a sophomore and 18 as a junior.

"Jewel is a very dedicated athlete," Thomas Stone Coach Bob Pitts said. "She's been playing ball for a long time, and she's gotten better every year because she's willing to do what it takes to improve."

Said Clark: "I know that if I go to college, I won't be able to play down low. So I need to work on my outside shot. When I was younger, I couldn't step out and shoot the three, but now I can go two or three feet behind the line."

Clark is considering playing at Pennsylvania or Navy next year, she said.

Clark also grabbed eight of her 14 rebounds in the first half and had four offensive rebounds in the fourth quarter. And she didn't play the final 3 minutes 55 seconds of the game.

"She's the complete package," Pitts said. "She scores, she rebounds, she runs the break. There's nothing she can't do."

Said her mother, Karen Clark: "Jewel has always been a natural athlete. . . . Once she sets her mind to do something, she always gives it her best. . . . I'm very lucky to have a daughter like her."
