Ricardo Gonzalez has shot a second consecutive 65 to edge one shot clear of Bernd Wiesberger at the Johnnie Walker Championship at Gleneagles.
The Argentine, who shared the overnight lead with his Austrian counterpart, finished with five birdies to take the outright lead on 14-under-par.
English duo Tommy Fleetwood and Mark Foster are tied for third on 11-under, while America's Brooks Kopeka is just one shot further back.
Oliver Fisher and Francesco Molinari are both on eight-under and positioned well for a weekend assault.
Down at the bottom, Simon Dyson shot five-under to avoid the cut, which came at three-under-par. However, there was bad news for Thomas Bjorn (+2), who signed for a 74.
