NEW YORK-The New York Mets shut out the Baltimore Orioles 5-0 yesterday to take a 2-1 lead in the World Series.

Delighted by his team's second consecutive victory, Met manager Gil Hodges said, "We just picked up some more non-believers. Somebody must be rooting for us after what we did in this one."

Met pitchers Gary Gentry and Nolan Ryan yielded four hits in defeating Jim Palmer and the favored Orioles as 56.335 fans jammed Shea Stadium for the first home Series game in Met history.

Met batters produced six hits including home runs by center fielder Tommy Agee and first baseman Ed Kranepool. Starting pitcher Gentry aided his own cause with a two-run double-his first hit since August 3.

New York fielders reinforced their pitchers as Agee and shortstop Bud Harrelson made spectacular catches. In the seventh inning, with the bases loaded, Agee dove to grab a dropping line drive and rob Baltimore's Paul Blair of an extra-base hit.

"I sit between a gentleman from Upper Volta and a lady from the United Republic of Tanzania in the committee." she added. "Often, before the debate starts, we chat about our children and our household problems."
