Adam Scott stumbled with a chance to all-but ensure himself of becoming world number one, leaving Matt Every to claim his first PGA title at the Arnold Palmer Invitational. Reigning Masters champion Scott, who led by a record seven strokes through 36 holes and by three when the day began, struggled to a final-round four-over par 76 and settled for third. "I really think the putting let me down," Scott said on Sunday. "I am annoyed I didn't putt at all today. Poor, just out of sorts for whatever reason." Scott, the first Australian to win the Masters green jacket, would likely have dethroned Tiger Woods atop the rankings days before he defended his first major crown next month at Augusta National. Instead, tearful Every secured his first-ever berth at the Masters with an emotional comeback triumph by firing a final-round 70. "It's hard. It's tough," Every said as he wiped away tears. "You never know if it's going to happen. It's nice to get it done." Every won in his 93rd US PGA start, his best prior finishes being runner-up efforts in 2012 at the Texas Open and Children's Miracle network Classic. The 30-year-old from nearby Daytona Beach, whose father brought him to Bay Hill for years in his youth, took a $1 million top prize that was more than he had earned in any prior career season. A week that saw 14-time major champion Woods withdraw due to a back injury ended with an emotional final charge. Every led Scott by three strokes with three holes to play but found a cart path to the right off the 16th tee and hit a tree with his second shot on the way to a bogey. As quickly as the door opened, Scott missed a 19-foot eagle putt and pulled a four-foot comeback birdie putt left of the cup at the par-5 16th while Every rescued par from a bunker at the par-3 17th, staying two ahead of Scott. Scott missed a seven-foot par putt at 17 and even though Every closed with a bogey by missing a five-foot par putt, Scott's par was not enough. Scott said he knows what he needs to work on in practice and the driving range to get better. "Today I was a bit shaky but this course was asking a lot of everyone," Scott said. "My short game just wasn't there so that needs to be tightened up. "This shows I need to do a bit more work on it for it to hold up under the most pressure." Keegan Bradley, Scott's playing partner, missed a 30-foot birdie putt at 18 which would have forced a playoff and Every had his long-sought win. "(Missing) the last putt was a bummer but I'll take it," Every said. Scott matched the course record with a 62 Thursday and equaled the 36-hole mark with a 68 Friday but saw his record seven-shot lead trimmed to three entering Sunday. The Aussie found bunkers with his first two shots and missed a five-foot par putt at the first, dropping his lead to two shots. Scott found water left off the third tee on his way to another bogey that trimmed his edge to one shot over Every. Scott answered with a birdie of his own at the fourth to reach 14-under and lead by two, but he found a bunker off the tee at the par-3 eighth and took a bogey, slicing his lead back to one. When Every sank a 20-foot birdie putt at the 10th and added an eight-foot birdie at the par-5 12th to reach 14-under, the seven-stroke edge Scott enjoyed on Saturday morning had totally vanished. Scott fell two adrift when Every followed with a 13-foot birdie putt at 13 to reach 15-under. When Scott took a bogey at the par-3 14th, Every's advantage grew to three shots. Source: AFP
