Andrew Lister of Haymarket rolled to one of the two most lopsided victories in the opening round of match play of the 63^rd U.S. Junior Amateur Wednesday at Egypt Valley Country Club in Ada, Mich.

Washington-area players Ben Warnquist (Rockville) and Denny McCarthy (Burtonsville) also advanced to the round of 32 with victories Tuesday.

Lister, a Battlefield High senior who won the Virginia public school title last fall, defeated David Flynn of Elk Grove Village, Ill., 7 and 5. Lister started his round with a pair of birdies, won the first three holes and never trailed. The only other player who won by as decisive margin Tuesday was defending champion Jordan Speith of Dallas, Texas, a 7 and 5 winner as well.

Warnquist, a senior at DeMatha, had an equally hot start, making birdies on five of the first 10 holes en route to a 6 up lead and eventually a 5 and 4 victory over Peter Mathison of Jupiter, Fla.

McCarthy, a senior at Georgetown Prep who is playing in the tournament for the third time in the last four years, never trailed in his match with Grayson Murray of Raleigh, N.C., but needed to go all 18 holes to win 1 up.

McCarthy has the most interesting pairing in the round of 32 Thursday morning as he faces medalist and No. 1 seeded Curtis Thompson of Coral Springs, Fla. Thompson, playing in his fourth U.S. Junior Am, is the brother of women’s prodigy Alexis Thompson, winner of the 2008 U.S. Girls Junior Amateur.

Warnquist will play Bryson Dechambeau of Clovis, Calif. Lister faces Clemson-bound Stephen Behr of Florence, S.C. Morning winners advance to the round of 16 Thursday afternoon. The quarterfinals and semifinals are set for Friday, the finals for Saturday.
