Clemson was one of nine teams in Baseball America's top-15 to lose on opening weekend - and therefore the series win was enough to maintain a No. 13 ranking in the poll.
ACC favorite Virginia also suffered an Opening Day loss to Kentucky, but recovered to beat VMI and UNC-Wilmington and stay No. 1 overall.
Florida State moved up two spots to No. 4 after a dominant weekend versus Niagara. Their starting pitching staff threw 17 shutout innings.
South Carolina moved up to No. 5 after their series sweep, while N.C. State dropped one (No. 6) after Sunday's loss to Canisius.
No. 16 Miami (2-1) and No. 17 UNC (1-1) round out the ACC's reps in the top-25.
