CLEMSON -- DeAngelo Mack hit a tiebreaking solo home run in the ninth to lead South Carolina to a 3-1 win over No. 19 Clemson on Saturday. The Gamecocks (4-0) have won five in a row and eight of the last nine against the in-state rival Tigers (4-1). The teams will play this afternoon in Columbia. South Carolina pounded out nine hits, but left five men on base through eight innings and only managed a run on Jeffery Jones' first-inning double. Jones' RBI scored Whit Merrifield, who hit a one-out triple to left center. Clemson tied the game at 1 in the sixth on Matt Sanders home run. The Tigers had only two hits, compared to the Gamecocks' nine. Gamecocks reliever Alex Farotto (1-0) picked up the win, allowing no hits, walking one and striking out two in 2 2/3 scoreless innings. Tigers reliever Graham Stoneburner (0-1) allowed three hits and two runs in an inning to get the loss. Mack's homer gave the Gamecocks the go-ahead run, but Bobby Haney's RBI single gave the visitors a little breathing room. Haney knocked in Andrew Crisp. USC's Sam Dyson and Clemson's Trey Delk pitched most of the way. Dyson pitched 6 1/3 innings; he gave up a run and walk as he struck out five. The rivals will meet three more times this season, including today's 1:30 p.m. showdown in Columbia.
