Overview

• Lee carded nine birdies over 16 holes after opening on the back nine, ending with a 9-under-par 63 that ties Detroit Golf Club’s course record.
• He held a one-stroke advantage over Andrew Putman after the opening round.
• Lee gained just over three strokes on the greens, crediting his short game for steadying him after an early bogey.
• His 63 matched his season best, a score he first shot en route to winning the Houston Open in March.
• His sister Minjee’s third major victory at the Women’s PGA Championship earlier this month has served as a key source of motivation.
