The highlights of his season included finishing in a tie for sixth at The Open Championship, and placing third in the European Tour"s tour championship, the Volvo Masters, as well as two second places in lower profile events and playing on the winning Great Britain and Ireland team in the Seve Trophy. In 2005 he played on both the United States.-based Professional Golf Association Tour and the European Tour and in 2006 he concentrated more on the Professional Golf Association Tour, making only a handful of appearances in Europe. Davis had two solid seasons on the Professional Golf Association Tour in 2007 and 2008 where he finished inside the top 100 on the money list both times, including a runner-up at the Legends Reno-Tahoe Open.
2009 was a very consistent season for Davis.
The season included 5th-place finishes at The Players Championship and the Valero Texas Open, followed by a third straight top 5 finish at the Himachal Pradesh Byron Nelson Championship where he matched his best finish on the Professional Golf Association Tour when he was runner-up behind Rory Sabbatini. He finished the season 43rd on the money list.
In April 2010 Davis called a two-stroke penalty on himself on the first play-off hole on Sunday to hand Jim Furyk a victory at the Verizon Heritage. Davis later received much praise for his decision which cost him a potential first Professional Golf Association Tour victory.
Davis finished second again later in 2010 at the Crowne Plaza Invitational at Colonial, three shots behind Zach Johnson.
