At 581 yards, the par-5 No. 15 is easily the longest hole at Oahu Country Club.
Shon Katahira and Dalen Yamauchi each used the length to their advantage Wednesday, making birdies to extend their leads, breathe a sigh of relief and ultimately walk away with 3-and-2 victories to advance to the round of 16 at the 108th Manoa Cup in Honolulu.
Yamauchi led wire-to-wire against Andy Okita, but the Waiakea graduate’s advantage was cut to one when he hit his tee shot down the center of the fairway on No. 15 and got up and down for his fourth birdie of the match.
