MEDINAH (Illinois), Aug 18: Ryder Cup hopeful Lucas Glover and fellow American Chris Riley took charge at the PGA Championship on Thursday while Tiger Woods and Phil Mickelson moved ominously into contention.
Glover, 14th in the standings with the 12-man Ryder Cup team to be finalised on Monday, and Riley fired six-under-par 66s to finish a benign day at Medinah Country Club one stroke ahead of the chasing pack.
Compatriot Billy Andrade, a late addition to the field on Tuesday after 1995 champion Steve Elkington withdrew for personal reasons, was alone in third after shooting a blemish-free 67.
Although Medinah's 7,561-yard No 3 Course is the longest layout in major championship history, soft conditions and friendly pin positions exposed it to low scoring.
Glover birdied three of the last four holes to set the pace on a calm, clear morning before Riley joined him at six under with a seven-birdie display on a damp and overcast afternoon.
Briton Luke Donald, Americans Davis Love III, Stewart Cink and JJ Henry, Swede Henrik Stenson and Australia's Robert Allenby were on 68.
Most eyes were focused on the high-profile grouping of tournament favourite Woods, Masters champion Mickelson and US Open winner Geoff Ogilvy of Australia who all carded 69s.
Woods, chasing his 12th career major after winning last month's British Open at Hoylake, recovered from an opening bogey at the 10th with birdies at the 12th, 14th, 15th and seventh.
Among the other big names at Medinah, Sergio Garcia opened with a 69, Retief Goosen and Jim Furyk shot matching 70s, Ernie Els returned a 71 and twice champion Vijay Singh bogeyed the last for a 73.
