Mickelson, who became the first American player to participate in 10 Ryder Cups, went 2-1-0 at Gleneagles, including a Sunday singles victory over Stephen Gallacher, 3 and 1.
More than likely, however, it will be U.S. captain Tom Watson’s decision to bench Lefty for an entire day for the first time in his career on Saturday that will stay with the veteran.
After going 1-1-0 on Day 1 paired with Keegan Bradley, Mickelson sat out the morning fourball session and tried, twice, to persuade Watson to send him and Bradley back out in the afternoon.
“He didn't play very well (Friday),” Watson said on Saturday. “I mentioned that and I told him that. I said, ‘You struggled yesterday.’ And whether that was from being tired or the course not being set up exactly for his type of game; I had to make that decision.”
On Sunday, Mickelson played his best golf of the week, going 6 under par for 17 holes and winning his last three holes to close out the match.
