Jayson Castro has always been the ultimate closer in his decorated career, be it for TNT Tropang Giga in the Philippine Basketball Association (PBA) or Gilas Pilipinas in international play.

The veteran guard at 36 years of age just reminded everyone about it in the ongoing PBA Philippine Cup semifinals between the top seeded Tropang Giga and the Magnolia Hotshots.

With TNT on the brink of a Game 3 loss and a critical 1-2 series deficit, Castro took matters into his own hands and sank a booming game-winning triple in the waning seconds to pull off a 93-92 thriller before a huge Sunday crowd at the Smart Araneta Coliseum.

Castro's heroic came off a blitz as the Tropang Giga no longer has a timeout and had to dribble his way from a full-court inbound after Mark Barroca's own clutch basket gave the Hotshots a two-point lead.

The daring act by "The Blur" was reason enough for him to be adjudged as Cignal Play-PBA Press Corps Player of the Week midway through the Final Four.

In the first three games of the semis, Castro averaged 15.0 points behind a 47-percent three-point clip (7/15), laced by 5.3 assists and 5.0 rebounds for an all-around campaign.

That's on top of his unparalleled leadership role for the reigning Philippine Cup champion, which seized a 2-1 lead in the best-of-seven series.

"It was still a good shot either I make it or I miss it. That's what the defense gave me so as a veteran, I have to shoot it. At the same time, we need to win in Game 3," Castro said.

The veteran playmaker finished with 16 points, two rebounds, and six assists in the Game 3 win.

He had 12 markers, five rebounds and five assists in TNT's 108-96 Game 1 win, before putting up 17 points, eight boards, and five dimes in their close 92-88 Game 2 defeat.

Castro, a seven-time champion and two-time Finals Most Valuable Player, bested his teammates Mikey Williams as well as San Miguel's CJ Perez and June Mar Fajardo for the weekly honor being handed out by the men and women regularly covering the PBA beat.
