Andrews paced the scoring with 14 points, Thomas and Russell had 12 each and Stallings chipped in with 10.
Sunnyvale stepped on Malakoff early, opening a 42-15 halftime lead, and it went on to a 65-33 victory on Tuesday.
The Raiders once again had four players in double figures, with Andrews tallying a game-high 21 points, Thomas scoring 13 and Stallings and Russell adding 11 and 10, respectively.
