Ramon Morla's seventh-inning grand slam capped the Jackson Generals' 9-5 victory over the Biscuits on Wednesday.
Morla's blast gave Jackson a 9-2 lead before the Biscuits scored twice in the eighth and once in the ninth. Ji-Man Choi hit a two-run homer in the sixth, also off Montgomery reliever Austin Hubbard.
Kyeong Kang homered, singled, walked and scored twice for the Biscuits. His solo homer was in the ninth inning.
Morla's grand slam was the fifth against the Biscuits this season and the 27th all-time. It was the third by a Jackson player against the Biscuits.
