Jeev Milkha Singh turned in a roller-coaster four-over 74 to slip to the tied seventh spot even as Jyoti Randhawa and Daniel Chopra fell by the wayside after the second round of the 90th PGA Championships in Bloomfield.
Overnight joint leader, Jeev found the going tough at the Oakland Hills, nicknamed "the Monster", as he dropped seven bogeys against three birdies to take his total to two-over 142.
The seasoned pro was off to a sedate start and parred the first five holes before picking up a birdie on the sixth that kicked off his topsy-turvy day.
A bogey on the seventh followed by a birdie on the ninth left the erratic Indian one-over at the turn.
Jeev's backward journey started with a bogey on the 10th before he dropped four more shots between the 13th and 18th holes. A birdie-brace on the 11th and 12th was the only highlight of his eventful back-nine.
If Jeev's had a nightmarish day, Randhawa and Chopra were even worse carding 76 and 75 respectively.
While Chopra finished with a total of 10-over 150, Randhawa singed off two strokes adrift.
At the top, American J B Holmes (68) grabbed a one-stroke lead with a total of one-under 139. The trio of Charlie Wi (70), Ben Curtis (67) and Justin Rose (67) were tied for the second spot.
