Irvin Mendoza calmly sank two free throws with less than a second left to lift Marikina past Manila, 78-77, Tuesday night in a battle of debuting teams in the 2002 Maharlika Pilipinas Basketball League Mumbaki at the Paco Arena.

The clutch charities preserved the all-out effort of Alfren Gayosa, who was named best player of the thriller after compiling 21 points, 12 rebounds, six assists, and three steals for the Marikina Shoemasters.

Gilbert Ocampo added 13 points while Lord Casajeros posted 11 points and nine rebounds for the Shoemasters who were coached by PJ Navarro in the absence of regular mentor Elvis Tolentino.

It was a shocker for the Manila Stars, who pulled ahead at 77-76-following a three-point play by Ira Bataller with 3.9 seconds to go.

The 6-foot-4 Bataller, a former star of the University of Santo Tomas, poured nine, including two triples, of his 14 points in the last six minutes before fouling out with a duty foul on Gayosa, time down to 2.6 seconds.

Joseph Yeo returned to competitive ball for Manila and contributed 12 points, all from rainbow territory, seven rebounds, six assists, and two steals in a 28-minute stint.

Manila, being supported by David Roxas Construction, drew 25 points and eight rebounds from Kobe Monje and 14 points, five rebounds, five assists, and two steals.

Earlier, Valenzuela City continued its recovery with a 56-52 victory over debuting Makati.

Drawing another dominant performance from Jaymar Gimpayan, Valenzuela followed up its 79-67 conquest of Mindoro on Monday and climbed to 2-1.

The 6-foot-2 Gimpayan tallied 17 points, 24 rebounds, 3 steals, and 2 blocks to earn his second straight best player honors.
