The best players in the world are geared up this week for the second major championship of the season, the U.S. Open.

Chambers Bay Golf Course is set to play host to its first ever major championship. It was also the site of the 2010 U.S. Amateur, which was won by Peter Uihlein.

Martin Kaymer returns as the defending champion after running away with an 8- shot victory at Pinehurst No. 2 last year. It was the German's second career major title as he also took home the 2010 PGA Championship at Whistling Straits. Kaymer also became the first player ever to win the Players and U.S. Open in the same year.

Another big name that has been reeling recently is world No. 1 and 2011 champion Rory McIlroy, who missed his last two cuts at European Tour events. However, the Ulsterman does have three victories on the season and a total of seven top-10 finishes in 11 events worldwide, including a runner-up.

Masters champion Jordan Spieth is seeking his third win of the season and his second consecutive major title. The No. 2 ranked player in the world is having a career season with nine top-10s and seven top-5s in 16 starts, not to mention three runner-up finishes.

Six-time runner-up Phil Mickelson looks to finally break his winless streak and complete the career grand slam with a victory at Chambers Bay. Mickelson has not won since the 2013 Open Championship, but he comes in playing well of late with three top-4 finishes in his last five events, including a tie for second at the Masters.

Tiger Woods is back in the U.S. Open field after the three-time champion missed last year due to back surgery.
