In singles, the top-seeded Sarkissian had a first-round bye before posting a 6-1, 6-0 win against Jose Thomas of Bakersfield in a second-round match.
Campbell, the eighth seed, also had a first-round bye. He then cruised to a 6-0, 6-0 victory against Nathan Crosby of Pierce.
Sarkissian and Campbell will each participate in round-of-16 matches at 11 a.m. today. If they win, they will also take part in the regionals.
"Alex and Trevor in singles are both very good," said MacKay, whose team finished second in conference behind Ventura College and will await to see if it will be invited to the Southern California Regionals, which will begin Tuesday. "They went out there in their matches and did what they should do."
