Phil Mickelson has admitted that the USA's defeat to Europe in the Ryder Cup was 'one of the biggest lows of his career'.
USa took a 10-6 lead heading into the final-day singles before falling to a marginal defeat and Mickelson believes that losing from such a dominant position will have a lasting effect on the members of Davis Love III's team.
Mickelson said: "I think the first two weeks following the Ryder Cup was a really tough low, one of the biggest lows of my career.
"It was a very emotional time because we really thought we were going to win. We expected to win; we were playing well and we thought that we were going to do it on Sunday.
"I think that the disappointment will last a lot longer than a month. I feel that over the next two years, we'll still have the same disappointment from not winning this year's Ryder Cup."
Mickelson returns to action this week in the HSBC Champions event at Mission Hills Golf Club.
