The PGA of America's officials were most worried about Rochester's early-morning weather before this week's PGA Championship.
The 105th edition of the tournament, which had previously been held in August before being moved to May in 2019, was indeed delayed by over two hours due to frost, and even when it did begin, it was still very chilly, at least for golf.
This follows a relatively chilly Wednesday when athletes completed their final practice sessions for the second major competition of the year.

With six holes completed, Kazuki Higa, who is competing in the PGA Championship for the first time, is 4-under par.
The 28-year-old made a par on his first hole, No. 10, before reeling off four straight birdies and paring No. 15. Higa, who has four victories in his career, competed on the Japan Tour in 2017.
