Southern Miss 6, Samford 3

Southern Miss saw an early five-run lead slip away as Samford rallied for a 10-8 victory in 10 innings in the opening game of a doubleheader Sunday in Hattiesburg.

Danny Rodriguez was hit by a pitch and scored the go-ahead run in the top of the 10th inning on a squeeze bunt by T.J. Dixon. Hunter Swilling followed with an RBI single, and Samford reliever Parker Curry worked around some trouble in the bottom of the 10th to preserve the win.

Curry (1-1) allowed one run on two hits in five innings out of the bullpen. He walked one batter and struck out four.

Tim Lynch’s two-run double in the bottom of the sixth inning gave the Golden Eagles a 5-3 lead, their first of the game. They tied it earlier in the sixth on an RBI single by Jake Sandlin.

Sandlin also had an RBI double in the eighth inning to bring in USM’s final run of the game.

Sandlin finished 3-for-4 with three RBIs and a run scored, while Lynch had two hits and two RBIs. Burdeaux scored three runs.
