Arundel of Gambrills, Md., exploited Peary's hung on to down the Rockville school, 9-6, for the Maryland State AA baseball championship today at Essex Community College.

Peary was charged with three errors in the first inning, two miscues coming when outfielders uselessly threw home on Arundel RBI base hits. Husky pitcher Ken Lake was charged with a balk and a run-scoring wild pitch.

"I think Peary was the best team we've played all year," said Arundel coach Bernie Walters whose team closed with a 19-4 record. "If you'd seen us all year you'd know base running was our forte. If the team threw to the wrong base we took advantage of it."

Mark Carter led off for Arundel with a walk and was awarded second on Lake's balk. Craig Williams lined a double down the right-field line to score Carter and took third on Neil Herrick's single. Herrick took second as right-fielder Craig Case threw home and catcher John Baldwin bobbled the throw.

Gary Collins walked to load the bases and Steve Doherty struck out before Tom Kimble stroked a single up the middle to score Williams and Herrick. Collins and Doherty each took an extra base when center-fielder Rob Dompka threw home, rather than to third.

Collins scored on a wild pitch and Luis Ruiz singled Doherty home for Arundel's fifth run.

Herrick cleared the center-field fence with a long blast in the second inning to raise Arundel's lead to 6-0.

Peary struck back for four runs in the top of the third as Chase capped a rally with a bases-loaded triple. With two out, Dompka tripled over center fielder Carter's head. Steve Dragos walked and Lake singled Dompka across. Jim Jeffries walked to fill the bases before Chase barely missed a grand [WORD ILLEGIBLE] by hitting the top of the centerfield fence as Peary moved to within 6-4.

Arundel used two hits to add a run in the bottom of the fourth and Peary responded with an unearned run in the fifth to make the score 7-5.

Arundel sent southpaw Lake to the showers by opening the fifth with three straight hits and scored two runs to extend its lead to 9-5.

Dompka tripled again for Peary and scored on Dragos' groundout for Peary's final run. Dompka finished with three hits in four at-bats.

Lake, who was 10-0 with a 0.63 ERA entering the game, was charged with 12 hits and eight earned runs in his four innings. He had gained victories in each of Peary's two previous state playoff games with 11 1/3 innings pitched since Tuesday. Lake, who had only given up seven earned runs all season, struck out eight and walked two.

"My arm was tired, I pitched seven innings Tuesday and and another four Thursday," Lake said. "You've got to just come back. We came back in the last two games. I thought we'd come back again. The only difference is they got some more runs."

Peary finished it season at 17-2.
