Merrill Kelly recorded the Biscuits' best start of the season, allowing two hits over seven innings in Montgomery's 3-0 win over the Birmingham Barons on Saturday.
Kelly (2-2) retired 17 of 18 batters at one point and didn't allow a hit from the first inning until the seventh. He walked two and struck out six. Relievers Marquis Fleming and Matt Nevarez polished off a three-hitter.
Barons starter Erik Johnson was almost as good for five innings.
After giving up an unearned run on a Mikie Mahtook RBI single in the first, Johnson didn't give up another hit until the sixth. He had retired 14 straight hitters entering the sixth.
Montgomery scored twice on two hits against Johnson (2-1) in the sixth. After loading the bases, the Biscuits scored on a Kyeong Kang groundball and a Riccio Torrez infield single.
