Billy Horschel shot an 8-under 64 in the final round of the Zurich Classic, maintaining his composure through a pair of weather delays for his first-career PGA Tour victory on Sunday.The 26-year-old former Florida Gator began the day two shots behind third-round leader Lucas Glover and surged into the lead with six straight birdies after the first weather delay. He finished at 20 under, narrowly holding off Shell Houston Open winner D.A. Points, who shot a final-round 65 to finish one shot behind.The second delay happened before Horschel could take his second shot on the 18th hole, giving him 50 minutes to reflect on what was at stake — $1.19 million and a two-year exemption.Horschel sealed the win with a 27-foot birdie putt on 18, after which he pumped his arms and screamed in triumph before sinking into a crouch and briefly pulling his cap over his face as the crowd roared.Champions TourJeff Sluman, a two-time runner-up with Craig Stadler at the Liberty Mutual Insurance Legends of Golf event, partnered with Brad Faxon for a one-stroke victory at the Club at Savannah Harbor.The duo had five birdies in a seven-hole stretch in the middle of their round to get to 23-under and made par on their final four holes to hold on for the win with a 193 total.European TourAustralia’s Brett Rumford eagled the first hole of a three-way playoff to win the Ballantine’s Championship in South Korea.Rumford was leading by two shots when he double-bogeyed No. 17.
