Alex Sarkissian and Trevor Campbell, the Vaqueros' top-two singles players, outplayed Middlebury's Andrew Peters and Zach Bruchmiller.
Sarkissian defeated Peters, 6-2, 6-3, and Campbell bested Bruchmiller, 6-4, 6-1. Campbell was up, 5-1, in the first game but Bruchmiller came charging back, winning four games in a row, before Campbell closed it out.
Campbell said he lost focus at first, getting it back in the second half of the match before cruising to a 6-1 win in the second game.
"I just needed to stay focused all the way through and be more consistent, not go for shots I didn't need to," Campbell said.
Sarkissian and Campbell weren't able to end the day undefeated, as they fell to Peters and Bruchmiller in doubles play, 8-4.
"Trevor and I are still figuring each other out and experimenting with a few things," Sarkissian said. "We've improved already and in a few months we'll be even better."
The loss dropped Sarkissian and Campbell to 11-2 in doubles this season.
"Alex and Trevor continue to get better at singles and remember, they're two singles players learning to play doubles," MacKay said.
MacKay thinks Saturday's loss to Middlebury (4-0) will serve as a lesson for his team heading into conference play next week. Glendale hits the road Tuesday to play L.A. Pierce College at 2 p.m. and will come back home to face Ventura at 2 p.m. on Thursday.
"Going into a week like we are, sometimes it's good to get your butt kicked," said MacKay, whose team fell to 8-6 on the season. "I think it gives you a reality check that if you don't play good tennis you're going to get beat."
