K.J. Choi has won the Senior Open Championship at Carnoustie, marking his first major victory in the senior league. After a rocky start with three bogeys in the first six holes, Choi played his final 12 holes in 5-under par, finishing 10-under overall and clinching the title by two shots over Australian Richard Green. Choi's decisive moves came on the back nine, particularly with an eagle on the 14th hole. This victory is historic as Choi becomes the first South Korean to win the Senior Open. Despite late-round challenges, Choi maintained focus and patience, attributes he credited to his success. His win also breaks a three-year victory drought, adding to his career tally of 33 wins.
