It's the fourth no-hitter in Portland Sea Dogs history and the second thrown in Binghamton.

Hart started and pitched 6 2/3 innings, issuing one free pass and striking out six batters. McGrath pitched 1 1/3 perfect frames in relief, striking out two, and Lau picked up his first save of the year, walking one and striking out one in a scoreless frame.

Luke Tendler drove in the Sea Dogs' first run with a line-drive single in the seventh inning, and Portland's second run came in the ninth on a sacrifice fly.
