The first half saw one team from Alabama win the Southern League South Division title. On Saturday, one of the state's other clubs took the second-half crown.
Michael Sheridan went 4-for-4 with a three-run homer and Matt Buschmann pitched seven solid innings as Montgomery cruised to an 11-4 division-clinching win over the Huntsville Stars.
Montgomery (38-30) finished second behind Mobile in the first half but prevailed in the second half as second-place Jacksonville was eliminated.
"I think in April we had a 10-15 record, came out of the chute a little slow, and from then on, May to September, we had one of the best records in the league," Biscuits manager Billy Gardner said. "They came together, the clubhouse chemistry was good with this team. They stay together, compete well."
Montgomery leads the league with 634 runs scored and a .730 OPS. Omar Luna tops the circuit with a .314 batting average, while Kyeong Kang slugged a team-leading 14 homers. Sheridan led the Biscuits with 58 RBIs.
Additionally, Rays' top prospect Hak-Ju Lee ranks fourth with 37 stolen bases and compiled a league season-high 21-game hitting streak from June 17-July 11.
On the mound, Kyle Lobstein (8-7, 4.06) and Alex Colome (8-3, 3.48) anchored the rotation with Buschmann, who gave up two runs on six hits while striking out five in Saturday's clincher.
"The thing about this group was they wanted to win the second half. They were determined to do it," Gardner said. "We had a run for our money with Pensacola and Jacksonville, they put some pressure on us. We could have easily caved in but didn't. It's a testament to the character of the club, a very resilient group."
It's the first playoff appearance for Montgomery since winning back-to-back Southern League championships in 2006-07.
