New York ? Maria Sharapova insists she’s more about substance than style, and now she has a second Grand Slam title to prove it.

Her strokes as piercing as her shrieks by the end, the third-seeded Sharapova beat No. 2 Justine Henin-Hardenne, 6-4, 6-4, Saturday night to win the U.S. Open final.

Sharapova burst onto the tennis – and endorsement – scene by winning Wimbledon in 2004 at age 17. She’d come close to adding more major championships since, but went 0-5 in Slam semifinals – until this tournament.

When Henin-Hardenne, a finalist at all four majors this year, slapped one last forehand into the net, Sharapova dropped to her knees and covered her face, then rose and trotted to shake hands. Then Sharapova hopped up and down, looking for the first time all night like any other teen.

She climbed into the stands, losing her way briefly until being helped by an usher, for hugs with her father and her hitting partner, who’ve been sending her signals during matches about when to drink water or eat bananas.

But Sharapova needed very little help on court against Henin-Hardenne, a five-time major champion who would have returned to No. 1 in the rankings with a victory.
