The Ryder Cup singles matches will begin at 4:05 a.m. EST Monday, according to event officials.
Plagued by heavy rains in Wales and frequent delays throughout the tournament, the decision to play Monday was made early Sunday when rains delayed the resumption of six team matches which had started the day before.
Officials had hoped to be able to complete the Ryder Cup on Sunday, but heavy morning rains made that impossible.
Weather should allow the European and American players to finish their rounds on Sunday and the forecast is promising for Monday, with warmer temperatures and clearer skies expected.
The first singles match will begin at 4:05 a.m. EST, followed by another match every 12 minutes. The 12th and final pair will tee off at 6:17 a.m. EST, and closing ceremonies will begin 30 minutes after the end of play. Only spectators with tickets valid for Sunday will be admitted to the Celtic Manor course on Monday.
The matches will be broadcast live in the United States on USA Network.
