Rather than finishing his degree at
Boston College, Davies decided to turn pro after three years of college. He was a well-established professional prospect, and was expected to be a very high
MLS draft pick had he chosen to accept the
Generation Adidas contract that he was offered. Ultimately, Davies decided to sign with Nike and try his luck in Europe rather than signing with
Major League Soccer.
Hammarby After an unsuccessful trial at Dutch club
Ajax, Davies signed his first professional contract with
Allsvenskan club
Hammarby IF in December 2006. As a result of his strong performance in 2008 there were many rumors regarding his transfer to a larger club elsewhere in Europe, but ultimately nothing materialized, and Davies returned to
Hammarby. The
2009 season began well for Davies, who scored four goals in the first nine league games. He also scored two
extra time goals in a
2009 Swedish Cup match against
Åtvidaberg, a ninety-ninth-minute equalizer and the winning goal just before extra time expired, to propel his club to a 3–2 victory in the third round of the tournament. In the ninth league match of the season, however, he was issued a five match suspension after he elbowed one of his opponents,
Örebro defender
Michael Almebäck in the face, resulting in a bloody mouth. Davies subsequently left Sweden to join up with the U.S. national team, marking his last appearance with Hammarby.
Sochaux On July 10, 2009, before returning from his suspension in Sweden, it was announced that Davies would sign with
Ligue 1 club
Sochaux. On August 15, in his second game with
Sochaux, Davies came on as a second-half substitute and scored twice; Sochaux ultimately lost the game to
Bordeaux, 3–2. However, after only eight appearances with the club,
Davies was seriously injured in a car crash while in the United States. and was finally placed in the gameday roster for the December 19 match against
Bordeaux. After having spent 2011 on loan to D.C. United, Davies returned to Sochaux. He made his first appearance since his accident in a 1–0 loss against
Rennes on February 11, 2012.
D.C. United After a ten-day evaluation period with the club during their pre-season, Davies signed on loan with
D.C. United for the 2011 MLS season. Davies made his debut as a substitute in the 52nd minute, against the
Columbus Crew on March 19, 2011, scoring two goals. A week later he scored his third goal in a 2–1 loss against
New England, and, as of May 4, led MLS in scoring with six goals scored. On June 24, Davies was fined $1000 for diving. On September 11, Davies scored a hat-trick off of three assists from Chris Pontius to beat
Chivas USA 3–0 in California. The win put United into tenth place in the standings, the final playoff spot, just above the
New York Red Bulls. United announced on December 1, 2011, that they would not exercise its December 1 option to secure his permanent transfer from Sochaux. After his loan spell at D.C. United, Davies spoke out about the club's disappointing season and said he was involved in a disagreement with the club's coaching staff.
Randers At the end of the season, Davies was on the verge of leaving Sochaux after reaching an agreement to terminate the contract with rumors spreading that he was on his way to join
AZ and American team-mate
Jozy Altidore but this was denied by technical director
Earnie Stewart, who insisted that the club had no interest in Davies. Eventually, Davies signed for Danish side
Randers on a two-year deal. Davies made his debut for the club, coming on as a substitute, in a 1–0 win over
OB on July 22, 2012. He finished his time at the club without making a start or scoring a goal.
New England Revolution On August 8, 2013, Davies was loaned to the
New England Revolution for the remainder of the 2013 MLS season. Davies made his Revolution debut, and home debut, on August 17, 2013, coming on as a 79th minute substitute for
Chad Barrett in a 2-0 win over the Chicago Fire. On January 9, 2014 Davies and Randers agreed to terminate his contract, allowing him to join New England on a permanent basis. Davies made his first start for the Revolution on July 19, 2014 in a 1-0 loss to FC Dallas. He scored his first Revolution goal on August 2 in a 2-1 loss to the New York Red Bulls. In the Revolution's 5 playoff matches, Davies notched a total of 4 goals and additionally recorded a game-winning assist. In the
2015 New England Revolution season, Davies led the Revolution in scoring, winning the club's golden boot award with 10 goals and 4 assists. Davies made 9 appearances for the Revolution in 2016, recording one goal, on March 6 against the Houston Dynamo in the season opener. Davies was waived from the Union at the conclusion of the
2017 season. Davies announced his retirement from playing soccer on March 2, 2018. == International ==
