Alexander started his professional career in Spain in 2005 with Spain's Aguas De Valencia.[5] He stayed with the club until 2007 before joining Greek side NO Patras in 2008 and stayed until 2009.[6]
2010 saw Alexander move to Australian National Water Polo League club Victorian Tigers and was named to the 2010 All Star team[7] en route to winning the 2010 NWPL Championship.[8] He remained with the club through the 2011 season.[9]
While competing overseas, Alexander has been with San Francisco, California-based Olympic Club as early as 2009.[10]
Alexander represented the United States on the Junior National Team from 2002 to 2003. Alexander, with other Juniors players, was named to the United States "B" team in May 2003 for play in the 2003 US Cup, held at Stanford Cardinal's Avery Aquatic Center.[11]
The US Cup served as a final tune-up for the 2003 FINA Junior Water Polo World Championships held in August in Naples, Italy, to which Alexander was named.[12] He led the team with 12 goals[13] as the US beat Belgium for 11th place.[14]
Alexander joined the full United States men's national water polo team in 2005, appearing in the 2005 ASUA World Championships as well as the 2005 FINA World Championships.[15]
He continued with the team and played in the 2007 FINA World Championships and 2008 FINA Men's Water Polo World League[16] in preparation for the 2008 Summer Olympics in London, but was one of the last cut players and ultimately was named as an alternate.[1][17]
Alexander persevered, setting his sights on the 2012 Summer Olympics. He participated with the senior national team in a number of major competitions including: 2009 FINA Men's Water Polo World League,[18] 2010 FINA Men's Water Polo World League,[19] 2011 FINA Men's Water Polo World League,[20][21] 2009 FINA World Championships,[22][23] 2011 FINA World Championships,[24] 2010 FINA Men's Water Polo World Cup,[19] 2011 Pan American Games,[25] and the 2012 Pan Pacific Water Polo Championships.[26]
Despite being a regular on the national team and participating in qualifying for the 2012 FINA Men's Water Polo World League,[27] Alexander missed out on being named to the Super Final roster. It was a sign of things to come as shortly after that he was not called to the 2012 Olympic team[28] and did not appear in any further major competitions for the team.
