Varner, Arnaus share halfway lead at Saudi International

Defending champion Dustin Johnson, six-time major winner Phil Mickelson and England's Tyrrell Hatton are six shots off the lead on four-under, with former British Open winners Henrik Stenson and Shane Lowry another two strokes back.

Varner got off to a slow start in blustery conditions and was over par after seven holes but then birdied four out of his next five holes.

"I've been playing this course now for a few years and starting to get the hang of it. Even on this wind, I've already seen it in the past, so I know my lines," said the Spaniard.

Fleetwood was happy to still be in touch.
