Luis Montano had his best Double-A start Friday night, but a couple of unearned runs unraveled it in the seventh inning.
And the Montgomery Biscuits scored all three of their runs in the seventh to claim a 3-1 victory over Carolina.
Montano (0-6) was pitching a two-hitter through six innings before the Biscuits put together their good-luck rally.
Carolina got a go-ahead run on base in the ninth before Matt Gorgen closed out the save.
Aneury Rodriguez (9-10) won his fifth straight decision for Montgomery.
Shaun Cumberland (pictured) scored Carolina's only run on a Logan Parker grounder in the second.
Jerry Gil (2-3, 9.39) will start Game 2 of the five-game set for Carolina tonight at 8:05 against Ryan Morse (3-6, 5.26).
