Matt Buschmann threw his fourth career complete game Tuesday, helping the Biscuits to a 3-1 win over the Pensacola Blue Wahoos and a doubleheader sweep.
Buschmann tossed a four-hitter with four walks and three strikeouts. He recorded nine groundball outs.
It's the second complete game of the season for Montgomery. Alex Colome threw a six-hitter over the regular nine innings to beat Mississippi on July 29.
Biscuits catcher Mayo Acosta hit a solo home run in the third inning to tie it 1-1. Montgomery took the lead in the fifth when Omar Luna came home on a passed ball. An Acosta flyball in the seventh brought in Luna to give the Biscuits a 3-1 lead.
