On the ninth green at the Tanjong Course at Sentosa Golf Club, players have turned into scholars. They circle the hole suspiciously, crouch, study, squat, squint, summon caddies for a read, wipe the face of their putter with their fingers. The green is the foreign land of golf. In an otherwise aerial sport, here everyone comes down to earth.
