Dufner 1 clear of Johnson at Colonial

Dufner posted a four-under 66 to finish three rounds at 15-under-par 195.

In his last 35 rounds played, Dufner has been on top of the leaderboard after
12 of those rounds. This is his third 54-hole lead of the year, and fifth of
his career.

Johnson carded a five-under 65 and is one stroke back at minus-14. The former
Masters champion had a chance to tie Dufner on 18, but his birdie effort slid
by the left edge.

Tom Gillis is alone in third at seven-under-par 203 after shooting 69 on
Saturday. Bo Van Pelt (71) is one back at minus-six, while Ryan Palmer (70)
and John Huh (69) share fifth at five-under-par 205.
