Sanderson, the No. 3 qualifier from the Cap Seven 4-A, stormed into the N.C. High School Athletic Association 4-A boys soccer quarterfinals Wednesday with a 4-1 win over Wilmington Laney.
The Spartans (17-6-4) will play at Green Hope (19-2-2) at 6 p.m. on Saturday.
"We had a good game," Sanderson coach Todd Worley said. "It was a really tight game most of the way."
Worley praised the play of defenders Ben Martin and Calvin Gaunce.
The Spartans took a 2-0 halftime lead on goals by Robert Inthisane and J.P. Rafferty.
The Bucs rallied in the 53rd minute to close the gap to 2-1. Renick Patterson hit a long free kick into the Spartans' box, and Oliver Klokman knocked it in.
Sanderson extended its lead to 3-1 on a long blast by Glenn Scott in the 70th minute. Martin's direct free kick in the final minute completed the scoring.
"It was a really weird game," Worley said. "I thought both teams played pretty well. For the most part, I thought we did a good job all around.
"Tonight I thought our offense beat them a few times, other than that, I thought it was a pretty even game."
