Osaka (Japan) : Rahil Gangjee (71) frittered away the early advantage with a mid-round collapse and slipped down the leaderboard to be tied 30th in the Asia-Pacific Diamond Cup here on Saturday. Gangjee, who recovered from a bogey start with three birdies on the trot, collapsed mid round five times between seventh and 15th. A birdie on 18th was some consolation, but it could have been a much better day than one over 71. Gangjee is now even par for three days and dropped to tied 30th after being tied 19 at the end of the second round. The other Indian, who made the cut, Himmat Rai carded 71 and is now one-over 214 and tied 37th on the leaderboard.
