Isaac Harrow's run-scoring double in the seventh inning broke a 3-3 tie and lifted Appalachian State to a 7-3 Southern Conference win over College of Charleston in college baseball action before 537 at Patriots Point Stadium on Saturday.

With the win, the Mountaineers improved to 20-17 and 9-12. The Cougars fell to 23-14 and 11-9. The series finale is Sunday at 1 p.m.

Harrow's game-winner capped ASU's two-out, seventh inning rally. Trailing 3-2 with two outs and the bases empty, Rand Smith singled to center and scored on Wes Hobson's double to right that tied the game at 3-3. Harrow followed with a double to center that scored Hobson for a 4-3 lead.

Cole Rakar's (Mt. Pleasant, S.C.) two-run single in the second staked Charleston to a 2-0 lead. The Moutaineers got a sacrifice fly from Chris Alessandria and an RBI single from Nick DeRose to tie the game at 2-2 in the sixth inning.

Charleston briefly recaptured the lead in the bottom of the sixth. Joash Brodin (Olympia, Wash.) reached on a fielder's choice with one out, stole second, and moved to third on an infield hit by Rakar. Brodin scored on a two-out wild pitch for a 3-2 Charleston advantage.

Hobson and Harrow had two-out run-scoring triples in the ninth that gave ASU a 6-3 lead. Harrow scored on a wild pitch for the final margin.

Chris Patterson (4-1) picked up the win in relief allowing no runs on two hits over 1 2/3 innings of work. Zach Quate worked the final two frames for his eighth save of the season. Corey Ashner (Kansas City, Kan.) suffered the loss in relief and fell to 1-2.

Rakar and Clay McCord (Atlanta, Ga.) led the Cougars with two hits each. Harrow had three hits and Hobson added two to pace the Moutaineers.
