The three male medal winners of the 2012 Olympic Games combined to only move up one spot in the latest ATP rankings on Monday, but it was the moves in points they made that really made the difference.

Gold medal winner Andy Murray picked up 660 points for his victory over Roger Federer, allowing him to move within 785 points of No. 3 Rafael Nadal. WIth Nadal struggling to come back from the knee injury that cost him his shot in the Olympics -- and the opportunity to defend his 2008 gold medal -- Murray will have the chance to move Nadal down a slot in the weeks ahead.

Silver medalist Federer used his Olympic points to open up a slight lead over Novak Djokovic for the No. 1 spot in the world. Djokovic lost the bronze medal match on Sunday, allowing Federer to expand his lead from 75 points to 165.

Bronze medalist Juan Martin Del Potro moved up one slot in the rankings to No. 8 in the world, his highest mark since the summer of 2010, when he lost all of his poitns from the 2009 US Open victory. 

Outside of the Top 10, the biggest move came from Ukraine's Alexandr Dolgopolov, who leapt nine spots to a career-best No. 16 by winning the crown at Washington, D.C., defeating Tommy Haas in the final.

Haas' summer comeback continued as he surged another 11 spots to No. 25 in the world, defeating No. 15 Mardy Fish in the semifinals. The 34-year-old German was last ranked in the Top 25 in May of 2010.

Headed in the exact opposite direction is France's Gael Monfils, who tumbled nine spots to No. 28 as injuries continue to plague him. Monfils has not played since Nice in late May, and was last ranked this low in October of 2008.

WTA

Much like in the men's rankings, the Olympic medal rounds saw a dramatic tightening in the top of the heap among the best female players on the planet.

Serena Williams' gold medal victory over Maria Sharapova means there are now just 775 points separating the top four players in the world.

Bronze medalist Victoria Azarenka held on to the No. 1 spot -- but just barely, seeing her lead shrink to new No. 2 Sharapova to a mere 100 points (8,820 to 8,720).

WImbledon runner-up Agnieszka Radwanska, a first-round flameout at London, fell back to No. 3 with 8,260 points. Silver medalist Williams made strong strides in her push back to the top, surpassing 8,000 points to 8,045.

The rest of the Top 10 remained the same, but outside of it, Vera Zvonareva continued her inexplicable slide, dropping two spots to No. 15.

Former No. 1 Kim Clijsters used her fourth-round appearance to jump back into the Top 30 at No. 29 as she begins the home stretch of her final WTA campaign, driving towards the US Open, where she is a three-time champion.
