Jason Day left the first round of the U.S. Open at Shinnecock Hills Golf Club after playing ten holes.

Jason Day 在 Shinnecock Hills 高爾夫球會打完十洞後，退出了美國公開賽的第一輪比賽。

Day's decision to stop playing was caused by a back injury, a problem that the 38-year-old Australian has faced many times in the past. This is the twelfth time in his professional career that he has had to withdraw from a tournament. He showed clear signs of pain during his final tee shot and warm-up, which meant he had to be taken off the course in a golf cart.

Day 決定停止比賽是因為背部受傷，這對於這位 38 歲的澳洲球員來說，過去已多次面臨此問題。這是他在職業生涯中第 12 次不得不退出比賽。他在最後一次開球與熱身期間表現出明顯的疼痛跡象，導致他必須乘坐高爾夫球車離開球場。

In terms of his performance, Day struggled during the start of the competition. He recorded a score of 7-over par through ten holes, which was made worse by six bogeys in a row starting at the 13th hole. Furthermore, this decline matches a general trend this season; although he finished second at the American Express in January and 12th at the Masters, he has rarely finished in the top 40 over the last two months.

在表現方面，Day 在比賽之初十分掙扎。他在前十洞記錄為 7 桿過標準桿，且從第 13 洞開始的連續 6 個柏忌（bogey）讓情況更加惡化。此外，這種下滑與本季的整體趨勢一致；儘管他在一月的美國運通賽獲得亞軍，並在大師賽獲得第 12 名，但在過去兩個月中，他很少能進入前 40 名。

Looking at his history, Day's success at the U.S. Open has decreased. He had five top-10 finishes in his first six attempts, including two second-place finishes in 2011 and 2013. However, he has not finished higher than 21st in this decade. Currently, Day is ranked 47th in the world, which is a significant drop from when he was the world number one for 51 weeks.

回顧歷史，Day 在美國公開賽的成績有所下降。他在前六次參賽中五次進入前 10 名，包括 2011 年和 2013 年兩次獲得亞軍。然而，他在這個十年中最高排名僅為第 21 位。目前，Day 的世界排名為第 47 位，與他曾蟬聯世界第一 51 週的時期相比，大幅下滑。
