England's Luke Donald and American Tiger Woods will go into the final round of the USPGA on Sunday tied on 14 under, two shots clear of the field.
Donald carded a six-under 66 on Saturday to match the target set by Woods, who had earlier equalled the course record with a seven-under 65.
The 30-year-old Woods has won all 11 of his major titles when either leading or sharing the lead after the third round.
If that is not daunting enough for the 28-year-old Donald and the chasing pack, Woods is looking for his second straight major victory after his triumph at Hoylake last month and third successive tournament win.
And just for good measure he has shot in the 60s in 13 of his last 14 rounds - and he won this title, which no European has won since 1930, when it was last held at Medinah in 1999.
Donald has been cut from 100/1 to 7/2 for BBC sports personality of the year since the tournament began on Thursday and you can follow his progress on Sky Sports 2 from 7pm.
