Jimmy Walker fired a final-round, 7-under 63 on Sunday and he ran away with a 9-shot win and successfully defended his title at the Sony Open in Hawaii.

Walker shot four straight rounds in the 60s to finish the week at 23-under-par 257, which was nine shots better than runner-up Scott Piercy. The win is Walker's fourth on the PGA Tour and his first since winning the AT&T National Pro-Am last season. Walker defeated Chris Kirk by one stroke at this event last year.

Piercy carded his second consecutive 66 to finish in sole possession of second place at 14-under 266 at Waialae Country Club. Harris English and Gary Woodland both shot 3-under 67s, while Matt Kuchar fired a 1-over 71 and the trio finished tied for third at
13-under 267.

Rory Sabbatini (63), Jerry Kelly (66), Brian Davis (67), Zac Blair (67), Max Homa (69), Shawn Stefani (68) and Justin Thomas (70) all ended tied for sixth at 12-under.
