Augusta (United States) – Unheralded leader Charley Hoffman and nearest rival William McGirt were ready for a morning charge as Friday’s second round of the Masters began in cool and breezy conditions at Augusta National.

Hoffman birdied five of the last seven holes, including four in a row starting at the par-4 14th, in windy conditions to shoot a seven-under par 65 in Thursday’s opening round.

That gave him a four-stroke edge on fellow American McGirt, the largest 18-hole lead at the Masters since Jack Burke’s four-shot margin over Julius Boros in 1955.

McGirt, playing in his first Masters, was off in the first group on the course Friday with Hoffman scheduled to tee off two hours later after what he expected to be an uncertain night’s rest.

“Will I sleep well? Probably not,” Hoffman admitted Thursday. “Obviously going to sleep on the lead at a major championship is not going to be the easiest thing. I look forward to it and I look forward to the challenge the next three days.”
