INVERNESS, Scotland — Ernie Els and Phil Mickelson endured frustrating second rounds at the Scottish Open as the tournament's headline acts were upstaged by some lesser-known players on Friday.
Chris Doak, ranked No. 341, was the surprise leader at the halfway stage of his home event after a second straight 66 left him at 12-under 132.
Matthew Southgate (64) was in a tie for second place with Ross Fisher (65), Peter Uihlein (66) and JB Hansen (65) a stroke back.
Conditions were ripe for low scoring on the Castle Stuart links but Els foundered on the greens and could only shoot a 2-under 70 to miss the cut a week before he defends his British Open title.
Mickelson, another four-time major winner, was tied for third after his first-round 66 but dropped back into a tie for 13th after a 70.
"I had no idea on these greens — I'm glad I'm leaving," said Els, who still felt his game is in good shape heading to Muirfield.
Past British Open winners Darren Clarke and Padraig Harrington joined Els in missing the weekend and defending Scottish Open champion Jeev Milkha Singh won't be around either after a second-round 74.
That put the Indian on 3 under — a shot below the cut, which was the lowest this season on the European Tour.
