JAMESTOWN — There were plenty of crooked numbers on the scoreboard at Diethrick Park on Monday night, but it was the last digit in Jamestown’s linescore that was particularly galling to Frank Jagoda.

Five errors leading to 10 unearned runs will tend to irk any manager.

Opportunistic Batavia took advantage of the Tarp Skunks’ misadventures in the field as well as a big night from Justin Espinal to post a 12-4 Perfect Game Collegiate Baseball League victory over Jamestown before a crowd of 1,016.

The win, which was credited to starter Jaden Sherwood (1-1), improved the Muckdogs to 11-7 while the Tarp Skunks dropped to 9-9.

The Muckdogs’ scored runs in six of the nine innings, including three in each of the third, fifth and eighth frames. All of them were unearned. The big hits were Espinal’s long home run over the left-field fence in the third; RBI singles by Tyler Castrataro and Espinal, and an RBI double by Braydon Horton in the fifth; and an RBI single by James Bolton in the eighth.

As it turned out, that was more than enough. Sherwood worked six innings for the win before giving way to Evin Hollandsworth, Castrataro and Garrett Beaver, who pitched an inning apiece.

The Tarp Skunks’ scored a run in both the third and fourth innings and two more in the seventh, but grounded into three double plays that stymied potential big rallies.

Sam Rickman (0-1), one of five Jamestown pitchers, took the loss.

Offensively, Jamestown was led by Falconer native Branston Lindquist, who had two hits, including a double, and an RBI; and Dom Costello who also collected a pair of hits. Nathan Borchardt also had a double.

The Tarp Skunks are off today and then hit the road Wednesday to meet Niagara. Their next home game is Friday against Niagara Falls. First pitch is set for 6:30 p.m.
