Chicago Fire After playing
college soccer at
UCLA, Bocanegra signed a
Project-40 contract with
Major League Soccer and was drafted by the
Chicago Fire with the fourth overall pick in the
2000 MLS SuperDraft. He spent most of the year with the Fire, playing two games on loan with Project 40. He won the
MLS Rookie of the Year Award for a team that made it to the MLS Championship match and won the
Lamar Hunt U.S. Open Cup. He became one of the top defenders in MLS, becoming the first player to win the
MLS Defender of the Year Award twice, in 2002 and 2003. Bocanegra scored five goals and had eight assists in his four years in MLS.
Fulham in 2007 Bocanegra was signed by
Fulham in January 2004, quickly becoming a fan favorite, garnering the nicknames
the Jackal and
the Black Snake. With Fulham, Bocanegra played primarily as a center back, but also as a left back and briefly as a
holding midfielder. During the
2006–07 Premier League season, he was Fulham's second leading scorer with five goals, behind fellow American
Brian McBride. On September 1, 2007, Bocanegra
captained Fulham for the first time in a Premier League match, a come from behind 3–3 draw with
Tottenham Hotspur. On September 15, 2007, he made his 100th appearance in the Premier League, all for Fulham, against
Wigan Athletic. He was released by Fulham on May 23, 2008.
Rennes Bocanegra was signed by
Rennes in June 2008. He received the number 3 shirt, which is his number for the United States. Bocanegra performed well in his first season in France, appearing in all 38 league matches. He scored his first league goal on March 8, 2009, in Stade Rennais's 2–0 victory over
Auxerre. He also scored a goal in a
UEFA Cup match and started all the club's
Coupe de France matches. These included the
2009 Coupe de France Final at the
Stade de France on May 9, 2009, where he scored Stade Rennais' first goal against Guingamp, in the 70th -1 minute.
Saint-Étienne On July 16, 2010, Bocanegra was purchased by fellow Ligue 1 club
Saint-Étienne for a reported fee of £400,000. He wore the number three shirt, as he did captaining the
U.S. during the
2010 FIFA World Cup. Bocanegra made his debut for the club, on the opening game of the season, in a 3–1 loss against
PSG. On December 5, 2010, he scored his first goal for the club, in a 2–2 draw against
Bordeaux; followed up his second goal in the
Derby du Rhône, but couldn't help Saint-Étienne win, as they lost 4–1. Bocanegra would be often used in first-team ins and outs in his first season. In a match against
Nice, on October 17, 2010, Bocanegra suffered whiplash injury, that kept him out for three weeks. In the 2011–12 season, Bocanegra took the captaincy temporarily following
Loïc Perrin's absence, on the opening game of the season, as Saint-Étienne win 2–1 against Bordeaux. This turned out to be his only appearance. He was linked with a move to Rangers, but was warned by Saint-Étienne that they would not sell him.
Rangers On August 17, 2011, Bocanegra joined
Scottish Premier League side
Rangers, signing a three-year deal for an undisclosed fee. Bocanegra made his debut for Rangers against
NK Maribor on August 18, 2011, in a
UEFA Europa League qualifier. His involvement in this match later caused controversy when Maribor filed a complaint to UEFA regarding the eligibility of Bocanegra's appearance, questioning whether he had the required clearance and paperwork. The protest was rejected by UEFA on August 24 as Maribor did not submit it within twenty-four hours of the match. His second goal came three months later, on December 17, 2011, during a 2–1 win over
Inverness Caledonian Thistle. Bocanegra quickly became a fan favorite after a series of solid and impressive performances alongside his center-back partner,
Dorin Goian. He was nicknamed
Captain America by the Rangers fans and captained
Rangers for the first time on January 8, 2012, during a 4–0 win over
Arbroath in the
Scottish Cup. During the season, Rangers went into administration over financial problems and a dispute with HMRC, leading to a 10-point deduction. Bocanegra spoke about the event, describing it as a "horrible experience" and encouraging players to light up the dejected fans. He also stated his desire to stay at the club, insisting he was happy there. During an Old Firm 3–2 victory, on March 25, 2012, Bocanegra received a straight red card after fouling
Georgios Samaras, conceding a penalty. After Rangers FC went into administration, in June 2012 the company's assets, including the players' contracts, were purchased by
Charles Green's consortium. Although many players departed because of this, Bocanegra's future was uncertain after not attending training, as he wanted to leave in order to play at a higher level. A few weeks later, on July 29, 2012, McCoist appointed Bocanegra captain for the first round of the Challenge Cup- a 2–1 win over
Brechin City. After the game Bocanegra announced his intention to stay, vowing not to walk away from the club. He then made six appearances at the start of the season. After being dropped by the national team, Bocanegra joined
Racing de Santander on a season-long loan in an attempt to keep his international career alive.
Racing Santander On August 31, 2012, Bocanegra joined Spanish
Segunda División side
Racing Santander on a season-long loan. Bocanegra expressed a desire to return to Rangers once his loan deal has expired. He made his debut for the club, on September 22, 2012, in a 1–0 win over
CD Mirandés. However, his time at Santander was considered "disastrous", as he failed to start the remainder of the matches, though still played regularly, coming on as a substitute. The club was relegated to next division. On April 9, 2013, Carlos announced on his
Twitter page that he would return to
Rangers for the
2013–14 season. Though announcing his return, U.S. National Team Coach
Jürgen Klinsmann warned Carlos not to play for Rangers next season.
Chivas USA In the summer of 2013, Bocanegra left Rangers and signed with
Chivas USA. Chivas USA traded up the allocation order with
Toronto FC to land his signature, sending a first-round
2015 MLS SuperDraft pick and an international slot to the Canadian club. Bocanegra retired at the end of the 2014 MLS season.{{cite web|url=http://www.espnfc.com/united-states/story/2021163/united-states-national-team-major-league-soccer-player-carlos-bocanegra-retiring|title=United States captain and MLS veteran Carlos Bocanegra retiring ==International career==
