British Amateur champion Jin Jeong has found St. Andrews more to his liking Saturday. Jeong was among 30 players to returned to the Old Course to complete a wind-swept second round, and he birdied the 18th hole to complete a remarkable 2-under 70.

Louis Oosthuizen (WUHST'-hy-zen) of South Africa holds a comfortable 36-hole lead, five shots clear of the field with a 12-under 137. His closest challenger is 50-year-old Mark Calcavecchia, the latest old-timer to challenge for the claret jug.

Jeong joined the group at 6-under 138 that included Lee Westwood and Paul Casey. The second round was suspended for about an hour because of fierce winds, which made it impossible for all 156 players to complete 18 holes.
