Each week, GolfChannel.com takes a look at the players who made moves up - and down - the various ranking systems in the world of golf.
• DeChambeau jumped 54 spots to No. 109 in the world after winning the DAP Championship in a four-man playoff. The event served as the first leg of the Web.com Tour Finals and ensured a promotion for DeChambeau beginning next season.
• Casey finished second for the second straight week, and as a result rose six spots to No. 16. It marks the Englishman's highest ranking since July 2011.
• Roberto Castro's third-place finish at Crooked Stick assured him a spot at the Tour Championship and also helped him move up 31 spots to No. 70, marking his first foray into the OWGR top 100 since May 2014.
• Thanks to some friendly divisor math, Ryder Cupper Thomas Pieters rose two places to No. 39 in the world despite withdrawing from the KLM Open before the first round because of an allergic reaction to a bee sting.
• A runner-up finish in the Netherlands helped Austria's Bernd Wiesberger go from No. 63 to No. 56 in the latest rankings, marking his first positive movement in the standings since April.
• A T-4 finish at Crooked Stick wasn't enough to extend the season for Ryan Palmer, but it did mean the American moved up seven spots to No. 61 in the world.
• Even with a win combined with Jason Day's withdrawal, Dustin Johnson merely cut into the Aussie's lead atop the world rankings. Day's average now stands at 14.1754, while Johnson's average improved to 11.8663.
