Atlantic Coast Conference teams started 8-2 in NCAA baseball regionals Friday, with Clemson hitting a tournament record seven home runs in its victory, defending national champion Virginia winning easily and Duke getting hammered in its first appearance in 55 years.
Chris Okey and Mike Triller hit two homers apiece for No. 7 national seed Clemson, which routed Western Carolina 24-10 in Clemson, South Carolina. Half of Clemson's 14 hits were home runs, and seven Catamounts pitchers combined to issue 17 walks.
Virginia set a school tournament record with 20 hits and scored at least one run in the second through eighth innings to beat William & Mary 17-4 in Charlottesville, Virginia.
No. 2 national seed Louisville and No. 3 Miami also gave the ACC wins, as did Florida State, Wake Forest, Boston College and North Carolina State.
Duke, which hadn't appeared in the NCAA Tournament since 1961, lost 11-1 to UNC-Wilmington. Georgia Tech accounted for the ACC's other loss, 7-6 to UConn.
The ACC set a league record with 10 teams in the field.
A look around the country:
UPSETS OF DAY
No. 4 regional seeds Rhode Island and Utah pulled the biggest surprises.
The Rams knocked off host South Carolina 5-4, led by Tyler Wilson's 11 strikeouts over seven innings and Brett McManus' home run and three RBIs. The Gamecocks managed only six hits against Wilson and two relievers, and coach Chad Holbrook was ejected in the seventh inning.
The Utes beat Mississippi 6-5, with Hunter Simmons' single driving in pinch runner Chandler Anderson in the top of the 10th inning after Anderson had moved up to second base on a passed ball. Ole Miss had runners on first and second with one out in the bottom half, but Dylan Drachler got the last two outs.
GAME OF DAY
Austin Bush homered leading off the bottom of the 14th inning, giving UC Santa Barbara a 3-2 win over Washington in Nashville, Tennessee.
The Gauchos had runners on second base in each of the previous three innings before Bush drove Alex Nesbitt's 1-1 pitch deep over the right-field fence to end the 4-hour, 45-minute game.
Washington went up 2-1 in the 12th on a bases-loaded walk, but Devon Gradford homered leading off the bottom half to tie it.
Alabama State's Joseph Comacho, who was unbeaten in his last 36 starts (31-0) since February 2014, didn't make it out of the first inning in an 18-6 loss to Florida State in Tallahassee, Florida.
