On senior day, Kyle Blackburn came up to the plate with two on, two out and trailing by three in the bottom of the ninth. He laced his would-be third home run of the game to the track in left, but The Citadel’s William Ladd made the catch with his back to the wall to seal a 5-2 win and a three-game sweep over Georgia Southern Saturday in J.I. Clements Stadium. The Citadel (35-20, 24-6 Southern Conference) won the league’s regular-season title in game two, and got its third solid start on a row out of pitcher Michael Clevenger in game three.
