The death of Queen Elizabeth II prompted the suspension of play for the rest of the day.
All facilities have been closed with immediate effect by the world golf tour.
Queen Elizabeth II was Britain's longest-reigning monarch and a rock of stability across much of a turbulent century. She was over the age of 100.
After her health took a turn for the worse, members of the royal family rushed to her side and she died at the castle.
The two Englishmen are tied for the lead at 8 under after the second round of the BMW PGA Championship. Thirty people were still on the course when play was stopped.
The captain of the Royal and Ancient Golf Club said that they were sad to hear of the death of Her Majesty. After her accession in 1952, Her late Majesty graciously accepted the Patronage of The Royal and Ancient Golf Club of St Andrew.
Her late majesty's patronage of the club was a great honor for its members. We are thinking of the Royal Family at this time of grief.

There will be a moment of silence prior to the start of the women's semifinals at the US Open.
Queen Elizabeth II attended Wimbledon four times. Virginia Wade won the women's singles title in the championship's 100th anniversary year.
She was a big fan of horses and attended the Kentucky Derby many times. The United Kingdom and the United States are both named after her.
When she ascended to the throne in 1952, she took over the breeding and racing stock of her father, King George VI.
She said in the documentary that her philosophy was simple. I like to breed a horse that is fast.
That is a big gamble to me. I love horses and the thoroughbred epitomizes a good horse to me.
The queen's jockeys wore purple, gold and scarlet, the colors of the royal racing silks, when they rode her horses.
She won all of the so-called "classics'' in British horse racing except for The Derby, which she attended for most of her life.
Estimate was the first horse owned by a reigning monarch to win the prestigious Gold Cup when it was owned by the queen. It was her first win in an elite race since 1989 and she was seen clapping enthusiastically as Ryan Moore finished first by a neck in front of 61,000 racegoers.
All racing will be suspended on Thursday and Friday to honor Queen Elizabeth II.
The statement said that Her Majesty was one of the most influential supporters in the history of horse racing. Her passion for racing and the racehorse shone bright throughout her life, not only through her close involvement in breeding and racing horses, but in her roles as a patron of The Jockey Club and the figurehead of Royal Ascot.
All racing is suspended for today and tomorrow as we begin to grieve Her Majesty's passing and remember her incredible life and contribution to our sport and our nation.
