One week before playing for a career Grand Slam, hometown hero Jordan Spieth fired a bogey-free nine-under par 63 Thursday to share the lead at the US PGA Byron Nelson tournament. Three-time major winner Spieth sank a 55-foot eagle putt on the par-5 18th at TPC Craig Ranch to match American J.J. Spaun atop the leaderboard after 18 holes at McKinney, Texas. "It broke left to right at the beginning and the rest of it was straight," Spieth said of his final shot. "I`m just trying to get to tap-in and cap off a good day, and I kind of started leaning because I thought it was going to miss left and it just kind of fell in the left side of the hole." 

It was a sizzling start for the 27-year-old Dallas native, who will try to complete a career Grand Slam next week by winning the PGA Championship at Kiawah Island, South Carolina. Spieth snapped a four-year win drought dating back to the 2017 British Open by capturing the Texas Open last month, winning the week before the Masters, where he shared third. Spectators were backing Spieth and unleashed a massive roar when he dropped the final putt. "I think late in the round they got some swing juice in them, and that certainly had something to do with it," Spieth said.
