Nick Kyrgios was fined $31,085 by the ATP on Wednesday after walking off the court during his opening match at the Shanghai Masters a day earlier.
The 13th-seeded Australian packed his bag and left the court after losing the first set 7-6 (5) to Steve Johnson on Tuesday.
Kyrgios was fined $21,085, his first-round prize money, for failing to see the doctor following his retirement. According to ATP Tour rules, it is mandatory to be examined by a physician if injured. He was fined an additional $10,000 for unsportsmanlike conduct. Hours after he abandoned the match, Kyrgios offered an apology on Twitter and said he had a stomach ache and sore shoulder.
