The limited par-5 opportunities at Yokohama Country Club—only two per round, both early in the layout—drive the closely balanced 50.5% implied probability on no albatross. The par-71 routing mixes 16 West Course holes with two from the East, leaving just 13 par 4s and three par 3s after hole 6, which reduces reachable scoring chances compared with typical PGA Tour venues that feature four or more par 5s. A strong 72-player field featuring major winners and recent form leaders adds volume across four rounds, yet albatrosses remain statistically rare events requiring precise long approaches. Weather, pin placements, and any late adjustments to the par-5 yardages or firmness could shift the narrow edge either way before resolution.
