Dan Arches stepped up big in the absence of Clint Escamis as Mapua High School thumped La Salle Greenhills (LSGH), 85-76, to forge a decider in Season 94 National Collegiate Athletic Association (NCAA) juniors finals on Monday at the Mall of Asia Arena in Pasay City.

With main man Escamis out due to a recurring knee injury, Arches exploded for 22 points, with 14 markers coming in the second half, to aid the Red Robins in forcing a winner-take-all Game 3.
