Maryland's baseball team scored 12 runs in the third inning, 10 with two out, and extended their home winning streak to 32 yesterday with a 15-12 Atlantic Coast Conference victory over league-leading Virginia at Shipley Field.

Playing in near-freezing temperatures, the Terrapins (9-10, 3-3 ACC) hit four home runs, two triples and two singles and used 14 batters in their third-inning rally against Virginia's losing starter Mike Gordon (3-3) and reliever Yogi Biggs. The comeback turned a five-run Virginia lead into a 13-6 Maryland advantage.

Maryland pitcher Joe Lynch (2-0) turned back Virginia with 4 1/3 innings of three-hit shutout relief. Lynch entered the game after the Cavaliers (13-12, 4-2) pulled within one with a six-run fifth inning, led by second-baseman Steve Heon's three-run homer that finished Bob Romanovsky. Romanovsky gave up nine hits and 10 earned runs in 4 2/3 innings.

The game would not have been played had it not been an ACC contest. Both head coaches believed that it would be impossible to reschedule the game.

"It was so cold, I didn't even break a sweat," said Lynch, who struck out three and walked none. "I couldn't throw a curve ball because I had no feeling in my fingertips."

The Cavaliers took a 4-0 first-inning lead and made it 6-1 in the third on a two-run homer by Donnie Meeks, who had four runs batted in.

But Gordon fell victim in the third to the unpredictable Shipley Field wind, which stopped blowing in from left field. He yielded a one-out, two-run homer to Tony Larioni, two walks and a single. Gordon got the next batter to ground out, but designated hitter Dub Daniels hit a three-run homer to center. Steve Miller reached base on an error, Bob Zavarick tripled and Jimmy Brooks homered to make it 10-6. Larioni walked, Tim Gordon tripled and Craig Chase finished the scoring with a two-run homer, providing the eventual game-winning RBI.

Virginia had a chance to tie in the eighth when Glenn Harris, who reached base five times, singled, and George Priftis doubled to left. But Lynch struck out Meeks on a 3-2 pitch and retired designated hitter David Lynch on a foul pop.
