MANILA -- The San Sebastian pair of Kenneth Villapando and Rhinwil Yambing along with PBA 3x3 veteran Kim Aurin were among the players who stood out on Day 1 of the 2023 Gatorade Draft Combine at the Gatorade Hoops gymnasium in Mandaluyong.

Villapando recorded the fastest time in the three-quarter-court sprint with a clocking of 2.81 seconds, while Yambing had the highest standing vertical leap with 34.5 inches.

Aurin, who suited up for Barangay Ginebra in both the 3x3 tournament and On Tour, led four others who emerged best in the reaction test with a perfect score of 100 percent. The other rookie prospects who achieved the same were Jose Carlos Cullar (La Salle), John Gob (UP), and Enoch Valdez (Lyceum).

Per reports, all three players submitted excuse letters to the PBA Commissioner's Office.

Another San Sebastian stalwart in Larry Arpia had the record in the max vertical leap of 43 inches.

Former San Beda big man Kemark Carino, who suited up in the Japan B. League, had the longest reach (standing) and wingspan with 105 and 86 inches, respectively.

Tsutonomi Tateishi, formerly of Santo Tomas and Benilde, shared the longest reach (standing) with Carino also at 105 inches.
