CLEMSON — In his second career start, backup South Carolina quarterback Dylan Thompson threw for his second 300-yard game leading No. 13 South Carolina to a 27-17 win over No. 12 Clemson, its fourth straight win over Clemson.

It is just the second time in the rivalry’s history South Carolina has won four straight games over Clemson and it is the first time it happened since 1951-1954.

Thompson filled in for an injured Connor Shaw who was unable to play due to injury.

On a third-and-goal play with four minutes to play, Thompson waited and waited in the pocket and found Bruce Ellington open in the middle of the end zone to give South Carolina a 27-17 lead with 4:17 to play.

Thompson shredded the Clemson secondary all night as Clemson was unable to consistently pressure Thompson.

A quarter earlier, on a 3rd-and-16 play from Clemson 34, the Tigers rushed only three and were unable to pressure Thompson who found Ace Sanders running uncovered over the middle of the field. Clemson safety Rashard Hall missed a tackle and Sanders walked into the end zone to give the Gamecocks a 17-14 lead early in the third quarter.

Thompson completed 23 of 41 passes for 310 yards and three touchdowns.

While Clemson struggled to disrupt Thompson, Jadeveon Clowney wrecked havoc on the Clemson passing game.

Clowney sacked Clemson quarterback Tajh Boyd four and a half times and another pressure caused one of two Boyd interceptions.

Boyd had his worst career passing day against South Carolina last season and might have had his second worst day today when he completed just 10 of 23 passes for 174 yards and one touchdown.

Clemson held a 14-7 lead in the first quarter after Boyd hit DeAndre Hopkins with a 43-yard touchdown pass but Clemson did not score another touchdown the rest of the night.
