(UPDATE) GUIDO van der Valk put up a solid start but only pulled ahead on a stirring eagle-spiked windup as he led the assault on Mimosa Plus' Acacia Lakeview course with a 66, one stroke ahead of four others after 18 holes of the ICTSI Mimosa Plus Championship in Clark Freeport Zone in Pampanga on Tuesday.

After birdying the first three odd-numbered holes, Van der Valk reeled back with a miscue on the par-3 No. 13 on what he described as a 'sloppy' shot but closed out with a birdie-eagle-par-birdie feat to string a pair of 33s and surge past Nilo Salahog, Reymon Jaraula, Japanese Toru Nakajima and Taiwanese Ting Yu Chen.
