A poor back-nine marred Jeev Milka Singh's card as he turned in a one-over 71 to slip to the tied 36th spot after the second round of the WGC-Bridgestone Invitational Akron, Ohio.
The seasoned Indian pro, playing his first tournament after being laid low by a rib injury for three weeks, has total of one-over 141 after two rounds at the Firestone Country Club.
A 10th tee starter, Jeev parred five holes on the trot before stumbling to a triple-bogey on the 16th. He managed a birdie on the next hole but dropped a stroke on the 18th to make the turn three-over.
His front nine was markedly better as he picked up two birdies on the first and fifth and didn't drop a single bogey to make some amends for the back-nine slump.
At the top, Irishman Padraig Harrington held on for a one-stroke lead after returning a 69 in the second round. Harrington totalled seven-under 133.
South African Tim Clark (68) occupied the second spot.
