Rankings mover of the week: Bradley Klahn

   Bradley Klahn continued his comeback from back surgery by reaching the singles final and winning the doubles title in the recent $25,000 Pro Tennis Championships of Calabasas in the Los Angeles area.
   Klahn, who won the 2010 NCAA singles title as a Stanford sophomore, soared 130 places to No. 633 in singles and 139 spots to No. 475 in doubles.
   The 26-year-old left-hander from the San Diego suburb of Poway climbed to career highs of No. 63 in singles and No. 131 in doubles in March 2014. However, he underwent his second operation for a herniated disc in February 2015 and missed almost two years.
