The Home Plate Club of Washington conducted the first annual All-Met High School Tournament at Robinson High School in Fairfax last night. A group of Maryland baseball stars declined the offer to participate, but it was the team of the District and private school standouts that wished they had stayed home.

The Virginia squad took advantage of sloppy play and 12 walks in defeating the visitors, 11-2.

Forty-four senior players from 28 area schools were selected to participate in what originally was expected to be a three-team tournament, including an entry from Maryland. When the Maryland team decided not to play, the "tournament" became a two-team showdown. The teams play again tonight at Robinson at 7:30.

The District/Private team scored early, taking a 1-0 lead in the first inning. A double by DeMatha's Kevin Campbell scored O'Connell's Gene Atwell. who had singled off Annandale's Bobby White, the winning pitcher. They would not score again until the ninth inning.

In between, the Virginia all-stars scored 11 times -- 10 in the first five innings -- off four pitchers to put the gane away.

Pat Miller of Oakton and Rob Lawall of Woodson drew walks to open the second inning before Washington-Lee's Tom McGraw singled to drive in Miller. Lawall advanced to third on Steve Render's errant throw and scored on Pat Walker's ground out. McGraw made it home for 3-1 on a double by Langley's Robbie Hahne.

The District/Privates outhit the Virginia squad, 11-8, but left nine runners on base and were plagued with six errors that accounted for four unearned runs.
