The Alexandria Dukes, hurting for pitching earlier this season, got two more superb mound efforts yesterday but split a doubleheader with Salem. The Dukes won the opener, 4-2 and lost the nightcap, 2-1.

In winning four of their last five games, Duke pitchers have yielded only 22 hits in 39 innings. Pete Sinopoli (1-3) hurled a two-hitter in the opener yesterday, fanning seven. A fourth-inning two-run homer by Tony Merulla spoiled the shutout.

Jose Rodriguez's RBI single broke a 1-1 tie in the ninth inning for the Redbird win in the second game.

In the first game, Elwood Halland singled and stole second, and Terry Tyson's single gave the Dukes a run in the first inning. Earl Neal tripled to drive in Holland in the third inning. Holland later scored the winning run and Tyson added the final run on Joel Oleinik's single.

Holland's fine fielding in the fourth inning of the nightcap defused a Salem rally after Mike Quade had walked, stole second, went to third on a wild pitch and scored on Terry Salazar's single in the first. With the bases loaded and one out. Holland made a running catch of Jim Poff's fly and unleashed a strike to home to doubleup Scott Kuvinka.

The Dukes staged a lighting rally in the bottom of the fourth on three straight singles, with Bowman scoring on Greg's Burtt's hit to make it 1-1. Holland was thrown out attempting to score on an Oleinik grounder.
