Phil Mickelson did something in the Ryder Cup he'd never done before.Five notes to know from today's Ryder Cup action:

1- It was a big day for rookies. Teams from the United States and Europe that had rookies competing went a combined 5-1. Rookie-free teams were a combined 3-7.

2--The U.S. leads by 2 points after day 1. Over the previous 20 Ryder Cups, teams who lead by two or more points after two sessions go on to win two-thirds of the time (8-for-12).

History says the Americans could have used more pad, though. Those who lead by three or more win three-quarters of the time (6-for-8) Those who lead by four-or more have won four times in five chances.

3--Over the previous 20 Ryder Cups, the United States has held a lead of two points or more six times after the first two sessions. The two teams the lead was two, Europe won. The four times it was three or more, the United States won.

4--The team of Sergio Garcia and Luke Donald entered 14-0-1 combined in their career in foursomes entering their match with Phil Mickelson and Keegan Bradley. That loss-free streak ended with a 4 & 3 defeat.

5--This marked the first time in nine Ryder Cups for Phil Mickelson that he won two matches in the same day. He was paired with Keegan Bradley for each of his victories Friday.
