There were some major positional shuffles in this week's U.S. Ryder Cup standings after strong finishes in the WGC-Cadillac Championship by Bubba Watson and Phil Mickelson.

Watson jumped from sixth to second, thanks to a runner-up finish at Doral. Mickelson, who finished fifth, moved up one position to sixth and closed the gap significantly on Rickie Fowler and Brandt Snedeker. Less than 100 points separate fourth through sixth at this point in the season.

Brooks Koepka moved himself into one of the eight qualifying positions, bumping Patrick Reed to ninth. Otherwise, the top 12 players remain the same.

Since the 2016 Ryder Cup at Hazeltine in Chaska, Minn., will be played in an Olympic year (with golf included in the Games for the first time since 1904), there have been some adjustments made to the qualifying calendar for the U.S. Ryder Cup team.

You can read about the entire qualifying process here, but these are the key qualifying dates:

- Sunday, Aug. 28, 2016: The top eight will be finalized at the conclusion of The Barclays, which is scheduled to finish on this date, as opposed to the traditional closing of points at the conclusion of the PGA Championship, which will be played in July instead of August in 2016 due to the Olympics. It also affords players an additional two weeks from past years to earn a spot on points.

- Sunday, Sept. 11, 2016: Love will select three of his four Captain's Picks at the conclusion of the BMW Championship, scheduled to end on this day.

- Sunday, Sept. 25, 2016: Love will make his fourth and final Captain's Pick at the conclusion of the Tour Championship, scheduled to end on this day.
