With three straight birdies in the middle of her round, Amanda Steinhagen took control of the 85^th Virginia Women’s Amateur final Friday and went on to defeat Lauren Greenlief, 2 and 1, in a battle of Oakton High School graduates.

Steinhagen, 18, a spring graduate of Oakton who will play on scholarship at Longwood, negotiated the Glenmore Club in 4-under-par in the final round, giving Greenlief, a junior this fall at the University of Virginia, few opportunities.

It was the first Virginia State Golf Association title for Steinhagen and the second straight year that Greenlief, 19, fell in the finals. She lost last year in 20 holes to Virginia teammate Whitney Neuhauser, who caddied for Greenlief on Friday.

Steinhagen started her decisive run at No. 8, making a 25-foot putt for birdie, after Greenlief had drained a downhill, 27-footer on the same line for a par. The putt gave Steinhagen a lead she would not surrender. She followed with birdie putts of 4 and 10 feet on the next two holes to take a 3-up lead.

When Steinhagen made a 22-footer for birdie at No. 14, she went up by 4. Greenlief extended the match the birdies on the next two holes before Steinhagen closed it out with a tap-in par at No. 17.

Both players are members at International Country Club in Fairfax.
