Beasley began his professional career in 1998, as a member Major League Soccer's Project-40, directly out of High School (South Side High School), the first MLS player ever to do so. He became a member of the New England Revolution. At the time, Beasley was the youngest player to sign with MLS, a record since broken many times over.
Beasley was signed on November 11, 2010 (just one day before the 2010–2011 season) by the Missouri Comets of the MISL. Beasley was an offensive force all season-long for the team. He finished 3rd in the league in scoring with 54 points and tied for 3rd in total goals with 20. Beasley also had the second most game-winning goals on the year with three. Following the season he was named 2nd team All-MISL.
Jamar's brother, DaMarcus Beasley also is a professional soccer player, having played for the Los Angeles Galaxy, Chicago Fire, PSV Eindhoven, Manchester City, Rangers F.C. Hannover 96 and Puebla as well as the United States National Team who he has represented at four World Cups.
He appeared at the World Youth Championship in Nigeria with the U20 United States national team, but has enjoyed more success with the US Futsal Team than with the full-age national team. In 2008, Beasley represented the USA at the Futsal World Cup in Brazil.
