The Ryder Cup usually starts with four alternate-shot matches, although the home captain can choose the order. Seve Ballesteros also started with best-ball matches in 1997 at Valderrama.
Torrance said the second day will have alternate shot (foursomes) in the morning, followed by best ball in the afternoon.
The Ryder Cup will be played Sept. 27-29 at The Belfry in England.
In alternate shot, players trade shots until the hole is finished. In best ball, both players on a team play their own balls and take the lowest score.
Torrance said changing the order would allow him to better evaluate his players before the 12 singles matches Sunday.
'If I am going to play everyone before the singles, I would rather put someone who is not entirely on top of his game out in the foursomes, because I think foursomes is up in the air, anyway,'' he said.
He said by using the best ball format early Friday and late Saturday, 'I can put my strongest out in the first series and my strongest out in the last.''
