The 39-year-old Thompson, brother of the LPGA star Lexi Thompson and Tour player Curtis Thompson, carded a 4-under 66 on Monday at Cattail Creek Country Club in Glenwood, Maryland, making six birdies and two bogeys. He’s joined in the field by medalist Drew Nesbitt, former Oregon standout Norman Xiong and David Lingmerth, who triumphed in a four-for-one playoff for the final spot. While it’s been a minute since Thompson has played a PGA Tour event, he made 34 Korn Ferry Tour starts last year in the wraparound season. He made just nine cuts but posted two top 10s, including a T-6 last July at the Price Cutter Charity Championship. He’s also spent time caddying for his sister, including at the Solheim Cup.
