Former US Masters champion Zach Johnson denied Englishman Brian Davis a PGA Tour win with a record-breaking display in the Crowne Plaza Invitational.

Davis, who forfeited the chance of an earlier win at the Heritage Classic, held a one-shot lead heading into the final nine holes after birdies at the first, second, sixth and seven holes had moved the London player to 19-under par.

But Davis couldn’t maintain that momentum over the closing nine and it was Johnson who stormed through the pack to record the win. Johnson’s second successive round of 64 gave him a three-shot victory, but things might have been different had the weather not taken a hand in the finish.

After seeing a par putt lip out on the 14th hole, Johnson pulled his tee-shot on the 15th into the right-hand rough. Before he had had a chance to play his second shot, the players were called off the course due to a threat of electrical storms in the area. That break in the play was enough for Johnson to refocus his thoughts and when play resumed, Johnson found the green with his second and holed a 20-footer for birdie to get back in front.

For Davis those birdies just wouldn’t come and a run of ten straight pars before a closing bogey allowed Johnson in to record the win. Johnson went two in front of the Englishman after a 15-foot birdie putt on the 17th before a second weather-break was called.

45 minutes later, Johnson made par on the last to win his first tournament since the Valero Texas Open in 2009. Johnson’s total of 21 under is a record score for the Texas tournament; the final leg of the PGA Tour’s Texas Swing.

Davis finished alone in the runners-up spot, one shot ahead of Jeff Overton and tipster pick Ben Crane; the duo tied on 17-under par while Scott Verplank and Bryce Molder were a further shot behind.

US Ryder Cup captain Corey Pavin shot a second successive 67 and his third in four days to tie for seventh place with Ricky Barnes while Boo Weekly finished in ninth place. There was a three-way tie for tenth spot, with Scotland’s Martin Laird sharing with United States’ Pat Perez and another tipster pick, Bo Van Pelt.

Paul Casey finished in a tie for 13th place following a round of 66, but there was disappointment for Ian Poulter who finished with a round of 76 to prop up the leaderboard on 7-over par, four shots adrift of second bottom, Charlie Wi
