A pair of former big-league pitchers dueled back and forth in scoreless efforts Tuesday night at Santander Stadium.

For Bridgeport, knuckleballer Tomo Ohka went the distance. For the York Revolution, Northern York grad Anthony Lerew went six innings, a season high for a Revs starter.

Once Lerew left, Bridgeport got on the board two innings later, scoring a pair of runs in the eighth and tacking on two more in the ninth en route to taking the opener of the three-game series in York, 4-0.

The Revs (6-5) have now lost a season-high three straight games and five of their last seven after starting the year 4-0. But it's hard to spell doom from Tuesday night's loss.

Lerew went six scoreless innings on 79 pitches, 54 of them for strikes. He gave up five hits and struck out seven. The seven strikeouts is a season high for a Revs starter this season. He improved his ERA to 2.57 through three starts. After York right-hander Stephen Penney pitched a perfect seventh, relievers Mike Wuertz (0-1) and Ian Durham each gave up two runs in one inning of relief, but it was the first time either Wuertz or Durham has surrendered any runs this season.

Plus, York entered Tuesday with the Atlantic League lead in total runs scored before getting shut out for the first time this year thanks to Ohka (2-0), a 38-year-old right-hander who has more than 200 games of major league experience and last pitched in the United States in 2009 for the Cleveland Indians.

In his return to the states, Ohka is now a converted knuckleballer, and the Revs' batters clearly had trouble with him Tuesday. The righty held York to three hits with five strikeouts and no walks in a complete-game effort. Ohka has given up just a run in 11 total innings (0.69 ERA) over two starts this season for the Bluefish (7-4).

York put a runner in scoring position just once, when Ofilio Castro reached second with one out in the second.

York will try to get back on the winning track Wednesday when left-hander Alain Quijano (1-0, 0.90 ERA) takes the mound for the Revs against former big-league pitcher J.D. Mitchell (0-1, 4.15 ERA). First pitch is scheduled for 6:30 p.m.
