ATENEO kept its spotless record in the 10th Shakey's V-League First Conference.
The two-time reigning champions booked their third straight win by making short work of Letran, 25-17, 25-16, 25-17, and book a berth in the quarterfinals on Tuesday at the Arena in San Juan.
Guest player Rachel Ann Daquis rose to the occasion by coming up with 13 points, while Fille Cainglet also had 13 for the Katipunan-based squad.
Ateneo had the game in control from start to finish that ace spiker Alyssa Valdez was played sparingly that saw her sitting out the entire second set. She finished with eight points.
Ateneo raised its record to 3-0 (win-loss) to remain on top of Group A.
Patcheree Sangmuan finished with a game high 16 points for the Lady Knights, who remained winless in the tournament.
