It's the first time BBC Four has hosted live sports coverage.
Heavy rain and strong winds across Scotland this morning meant that proceedings couldn't get underway at the scheduled time in St Andrew's, leading to play being extended into the evening.
With BBC Two off to the First Night of The Proms at 8pm, the BBC was forced to make the decision earlier today to move coverage across to BBC Four until close of play, rather than move the Proms to BBC Four.
As a result, You've Got a Friend, The Carole King Story won't be shown, but as of the time of publication, it is still scheduled for 1:00am, which would have been a repeat from 8pm.
The BBC was expecting Golf coverage be over in time for Rock n' Roll America, but play continued beyond 9pm, making use of the last light of the day.
