Shawn O'Malley scampered home on a Mikie Mahtook flyout with the go-ahead run in the Biscuits' 3-2, 10-inning win over the Jackson Generals on Saturday.
O'Malley led off the winning with a single and Hak-Ju Lee laid down a sacrifice bunt. Lee beat the play at first, leaving Montgomery with two runners on and none out.
Both advanced on a Ty Morrison bunt before the Generals intentionally walked Omar Luna. Mahtook flied to right to knock in O'Malley.
Lee finished with two hits and a walk to extend his on-base streak to 40 games.
