The Biscuits just left for Mississippi and are taking three extra players with them.
Outfielder Sergio Pedroza, catcher Christian Lopez and pitcher Jino Gonzalez joined Montgomery from Class A Vero Beach for the playoffs.
One of the three will be activated for the playoffs, which start Thursday. The first-round playoff roster has to be finalized by noon Thursday. The other two players will be activated only if the Biscuits (or Class AAA Durham) has an emergency need.
Pedroza, who had the majority of his at-bats at designated hitter, hit .286 with 22 home runs and 70 RBIs for Vero, while Lopez was a .230 hitter with 24 RBIs. Lopez also played in two June games with Durham.
Gonzalez was 5-6 with a save and a 2.86 ERA in 43 appearances. He allowed 81 hits in 91 1/3 innings.
