Jenkins allowed just four hits and a walk, while tying a career-high with nine strikeouts to pick up the win for New Hampshire.
Besides Jenkins, some former Phillies prospects came up big for New Hampshire - the AA affiliate of the Toronto Blue Jays - on the night.
Eastern League MVP, Travis D'Arnaud, opened the scoring in the bottom of the first when he singled to drive home another former Phillies prospect, Anthony Gose. With one out, Gose singled and went to second when Moises Sierra was hit by a pitch. Reading center fielder Derrick Mitchell threw to third to get Sierra on the play for the second out of the inning.
D'Arnaud and Gose combined to go 4-for-8 on the night.
Reading starter Tyler Cloyd battled over 6 2/3 innings, giving up eight hits, while also striking out eight hitters. Cloyd took the loss in the series opener.
New Hampshire notched their second run of the night on a solo home run by Mark Sobolewski in the bottom of the seventh.
Game two will be played in New Hampshire Friday night with Reading sending J.C. Ramirez (11-13, 4.50) up against New Hampshire's Nestor Molina. Molina pitched most of the season with Dunedin in the Florida State League and has gone 2-0 with a 0.41 ERA in five starts with the Fisher Cats.
