The Ducks offense has taken on a boom or bust approach to scoring runs lately. No, this isn’t a conscious choice, not by any means. But, at least in the short term, it has become their unfortunate identity. And Sunday it was bust, much to the chagrin of 5,732 fans in attendance on Jewish Heritage Night at Bethpage Ballpark in Central Islip.

The Ducks mustered only four hits in a 5-2 loss to the York Revolution, a team that they’ve lost nine of 13 games to this season.

Delta Cleary Jr. had two of the Ducks’ hits. Mike Blanke and Tyler Colvin each had RBIs.

“We have some new kids in there,” Ducks manager Kevin Baez said of his injury-plagued lineup. “. . . Right now, guys are not stepping up and swinging. It’s frustrating . . . We need to get better . . . We as a Duck organization, we’re embarrassed. We don’t accept this.”

Ducks starter Bobby Blevins got hit hard early, but settled down in the middle innings to keep his team within striking distance. The righthander allowed four runs on six hits, struck out six, and walked two in six innings.

York’s Frank Gailey allowed one run on four hits in 5 2⁄3 innings to earn the win.

York hit three home runs off Blevins, two of which came in the first inning. Jared Mitchell, the second batter of the game, launched a towering two-run home run over the leftfield fence. Two batters later, Kevin Rivers slammed a solo shot over the Budweiser advertisement in rightfield.

Designated hitter Michael Burgess hit a solo home run in the second inning to give York a 4-0 lead.

York (27-21) added a run off reliever Danny Burawa in the seventh. After the Revolution loaded the bases with no one out, Rivers hit into a double play that brought home Travis Witherspoon.

The Ducks (22-26), determined to get the rotation right by the time the playoffs start on Sept. 21, have continued to tinker. The team announced after the game that they acquired lefthander Jarret Leverett from the New Britain Bees, completing the Aug. 1 trade that sent pitcher Kevin Vance to New Britain for a player to be named later.

Leverett most likely will start Thursday in Lancaster, taking Mike Jackson Jr.’s rotation spot, with Jackson moving to the bullpen, Ducks president and general manager Mike Pfaff said.

Leverett is 4-7 with a 3.55 ERA in 28 appearances (10 starts).
