(UPDATED) The Philippine men's basketball team absorbed a shock 79-68 defeat to a Cambodian side that was heavily reinforced by naturalized players, Thursday evening at the Morodok Techo Stadium.

Cambodia nailed 12 three-pointers and led by as much as 21 points to hand Gilas Pilipinas a loss in its second game of the group stage in the 32nd Southeast Asian Games in Phnom Penh.

The host nation's naturalized players did the heavy lifting in the upset win, with Darrin Dorsey scoring 22 points on 7-of-14 shooting.

Christian Standhardinger had 14 points and 11 rebounds for Gilas Pilipinas while Justin Brownlee had 10 points on 3-of-13 shooting.

It was the first time in memory that the Cambodians beat the Filipinos in SEA Games basketball.

The imposing victory by the host pushed it alone on top of Group A with a 2-0 slate.

The Philippines dropped to an even 1-1 record, but still has a chance of advancing to the next round with a win over Singapore in its final assignment in the group stage on Saturday.

The Singaporeans remained winless in two outings, while Malaysia, which Gilas defeated in its first outing, 94-49, has an even 1-1 slate.

Chris Newsome was the other Gilas player in double digits with 11.

The Filipinos put on a semblance of fight starting the third period as Brownlee came alive and sparked the team's offense. His three point play cut down the lead to 50-40.

But the Cambodians retaliated behind an 11-0 run to post their biggest lead of the game at 61-40.

Cambodia only utilized a total of seven players, six of them naturalized.

Even before the game, Gilas already suffered a casualty in Calvin Oftana, who was diagnosed with a Grade 2 calf strain which he sustained in the game against Malaysia.

Oftana is likely out for the entire duration of the biennial meet.

The scores:

Cambodia (79) - Dorsey 22, Pridgett 17, Lopes 13, Peterson 11, Henderson 11, Hoeup 3, Morgan 2.

Philippines (68) - Standhardinger 14, Newsome 11, Brownlee 10, Perez 9, Tolentino 5, Phillips 4, Lastimosa 4, Ganuelas-Rosser 4, Lassiter 4, Amos 3, Ross 0.

Quarterscores: 26-14, 47-31, 66-47, 79-68.
