Navy batted around in the fourth inning, ripping visiting George Washington for seven runs on six of its 14 hits and went on to thump the Colonials, 12-5, in college baseball today at Bishop Stadium.

The Mids (12-2), who came in batting .346 as a team, trailed, 4-2, going into the big inning.Steve Komlo started the Navy burst by reaching first on an error.

After Phil Austin struck out, designated hitter Tim Wild singled off losing pitcher Dennis Minogue (1-6) and Perry Dietz walked to load the bases.

Leadoff man Mike Mullikin, a senior whose .441 batting average is second in the the area, lined a two-run single into right field and Jim Roberts singled in Mullikin to put Navy ahead, 5-4.

George Washington (6-12) brought in Matt Jones to replace Minogue.He yielded three more singles and the Mids benefited from another Colonial error that kept the rally alive. By the time Austin grounded out to end the inning, Navy had taken a 9-4 lead.

"We're a fair-hitting club," said Navy Coach Joe Duff (296 victories in his 19th year). "Having played four games in the last week has really helped our timing and consistency.

"With the wind in the batters' faces there was no sense trying to blast the ball out of the park. We tried to meet the ball and keep it on the ground and we were fortunate enough to get our hits consecutively," said the coach whose team has had 10 games rained out this season.

Duff used four pitchers, because of the poor weather. "We haven't had a chance to get a pitching rotation going," he said.

The game was shortened to seven innings because GW had to return to Washington to attend its sports banquet.
