Paul Casey capitalised on a late Patrick Reed error to claim a one-shot victory at the Valspar Championship, where Tiger Woods fell one stroke short.
Casey fired a six-under 65 on the Copperhead Course at Innisbrook Resort, safely negotiating the Snake Pit to set the clubhouse target at 10 under.
Reed moved alongside Casey but bogeyed the last to slip into a share of second alongside Woods, who closed with a one-under 70 to secure his best PGA Tour finish since 2013.
Masters champion Sergio Garcia matched Casey’s joint-low round-of-the-day to end the week in fourth, with Justin Rose slipping down the leaderboard on the back nine to finish tied-fifth.
Woods moved into a share of the lead with an opening-hole birdie and Rose followed suit to also get to nine under, as overnight leader Corey Conners bogeyed the par-five.
Brandt Snedeker briefly made it a three-way tie but slipped back with three bogeys in five holes from the second, as Woods handed Rose the outright advantage after missing from six feet at the fourth.
Casey made his move up the leaderboard by posting three birdies in a four-hole stretch from the fourth, before back-to-back gains from the 11th moved him alongside Rose.
Reed holed a 20-footer at the eighth to join the tie at the top, only for Casey to move ahead by holing a monster putt from off the 13th green and making a string of pars along the closing stretch.
Rose’s challenge faded with back-to-back bogeys from the 12th, as Reed produced a stunning approach at the par-five 14th to set up a two-putt birdie and join Casey two clear of the chasing pack.
Needing a final-hole birdie for victory or a par to force a play-off, Reed elected to putt from a tricky position on the green and saw his ball roll back down the slope to his feet on his way to a closing bogey.
Woods struggled to make inroads during the final round but set up a grandstand finish by draining a stunning 44-foot birdie on the penultimate hole, but was unable to replicate it at the last.
A final-round 72 left Rose three off the pace alongside Rory Sabbatini, as overnight leader Conners closed with a six-over 77.
