Sung Kang closed with a 4-under 67 on Sunday to finish at 23-under and win the 2019 AT&T Byron Nelson, capturing his first career PGA Tour victory.
Due to a weather delay during Round 3, Kang was forced to play 27 holes Sunday en route to the title. The 31-year-old took the lead on No. 15 with an incredible 23-foot birdie putt - one of three consecutive birdies - and never looked back, defeating Matt Every and Scott Piercy by two strokes.
It was the biggest win of Kang's career after competing worldwide as a professional since 2011. The South Korean's only wins to this point came on the Korean Tour back in 2013.
World No. 3-ranked Brooks Koepka finished fourth at 20-under after shooting a 65 on Sunday. The 29-year-old will now focus his attention on defending his title at the PGA Championship at Bethpage next weekend.
