MANILA, Philippines (UPDATE)—Gilas Pilipinas could not recover from a cold spell in the first quarter, and lost to the Adelaide 36ers, 85-75, at Meralco Gym on Sunday, the Filipinos' second tune-up game against the Australian club.

The Philippines won its first tune-up game against the visitors, 92-83, Friday, but could not complete the sweep after a subpar start that saw Gilas give up a 20-2 run to the 36ers in the final 6:32 of the opening frame.

Back-to-back 3-pointers by Jack McVeigh highlighted Adelaide's run, with only a floater from Andray Blatche keeping the Filipinos afloat.

Kiefer Ravena, playing in his first game after an 18-month suspension, tried to rally the team as he scored Gilas' first seven points of the second quarter.

But the 36ers were unstoppable from the perimeter, while the Filipinos bled for their points. Gilas was down 44-30 at the break, and then trailed by as many as 21 points in the second half.

The Filipinos roared back in the fourth, thanks to their shock troopers led by Gabe Norwood and Raymond Almazan. Blatche re-entered in the final 4 minutes, and his 3-pointer and split at the line brought Gilas within 7 points, 80-73, with 1:30 to go.

The 36ers did enough to hold them off, however, with Daniel Johnson making 2 free throws and Daniel Dillon nailing the dagger 3-pointer with 34 seconds to play.

Blatche led the Filipinos with 16 points, 6 rebounds and 5 assists, while Ravena had 11 points on 5-of-8 shooting in his first competitive game in 18 months.

Johnson led the 36ers with 16 points, while McVeigh finished with 12 markers.

Poor shooting from behind the arc doomed Gilas, as they made only 6-of-23 3-pointers, and shot 40% from the field overall. Adelaide, for its part, made 50% of its field goals, including 9 of 20 triples.
