Junior Axel Alvarez has put together quite a resume in his time at Oklahoma. The Spaniard earned All-America honors in 2014 and was named the ITA Central Region Rookie of the Year in 2013. Alvarez helped the Sooners win Big 12 titles in 2013 and 2014, and led Oklahoma to an NCAA Runner-Up finish in 2014. In 2015 Axel became the first Sooner ever to be ranked No. 1 in singles.
