Ferrera, 23, submitted a new national record in the hammer throw event to post the days worthiest performance under incessant rains.
So dominating was the Cauayan, Negros Occidental natives performance that it took him only two throws to register a 55.55 that smashed the current RP mark of 55.28 he himself set in last years Southeast Asian Games in Hanoi, Vietnam where he also copped the gold medal.
Only the heavy downpour that swept the metropolis in the afternoon prevented Ferrera from further improving his mark and closing in on the existing SEAG record of 58.80 owned by Malaysian Wong Teskui, who accomplished the feat on June 13, 1993.
"Sayang mas maganda pa sana kung hindi umulan," said Ferrera, who dedicated his effort to his late mentor Irish priest Fr. Colum OHalpin who trained kids in Negros Occidental.
Finishing way behind Ferrera were a pair of OHalpin studentsJero Perater and the formers younger brother John Albert Ferrera.
Perater finished with a silver medal with a throw of 49.15 while Ferrera, a 20-year-old second year marketing student at University of Baguio took the bronze with 45.47.
Ferreras coach Agustin Jarina of Army placed fourth with a throw of 41.87, far from the old 51.98 record he owned until 2002 when the young Ferrera entered the fray.
Armys Maristella Torres took advantage of the absence of Lerma Bulauitan-Gabito by ruling the womens long jump with a distance of 6.01 to beat Maricel Sibog of South Cotabato and Koreas Myong Hee Shin.
Sibog jumped 5.71 for the silver medal while Myong bagged the bronze with a jump of 5.63.
The Filipino-Americans, named the Philippine Overseas Team, continued to grope for winning form after two days in a row.
