UTICA — The Jamestown Jammers won their fifth straight game Sunday night, and again they did it in impressive fashion.

Jamestown broke open a 4-3 game with a seven-run seventh inning to pull away from the Utica Blue Sox for a 13-3 victory in the Perfect Game Collegiate Baseball League.

Christ Conley, who is now hitting .462 on the season after a 2-for-4 night, walked to open the seventh and moved to second on Skyler Valentine’s one-out walk. Collin Stack followed with a two-run triple to give the Jammers a 6-3 lead before Matt Cross walked and Jimmy Standohar was hit by a pitch to load the bases. Alex O’Donnell then hit a two-run single and Nick Bernick followed with a two-run double as Jamestown broke the game open. Conley drove in Bernick with a single to cap the seventh-inning scoring.

Conley, Chris Estrada, Stack, O’Donnell and Bernick each had a pair of hits for the Jammers with Valentine and Bernick hitting doubles. O’Donnell also hit Jamestown’s first home run of the season with a two-run blast in the eighth that scored John Conti.

Colin Johnston picked up his first win of the season in relief of starter Michael Ginther. Johnston went two innings, allowing one hit and one walk while striking out one. Ginther threw the first five innings, allowing four hits and three runs while walking three and striking out four. Nolan Hunt and Connor Ryan threw the final two perfect innings, striking out two each.

O’Donnell brought home a run in the second inning when he reached on a two-out error before the Jammers tacked on three in the sixth inning to make a winner of Johnston. Valentine had a two-run double and Bernick walked with the bases loaded to give Jamestown a 4-3 lead.

The Jammers return to action Tuesday with a 7:05 p.m. tilt at Newark.
