   Bradley Klahn, a 24-year-old Stanford graduate, tumbled 54 places to No. 221 in this week's world rankings.
   Klahn lost in the first round of last week's $50,000 Challenger in Burnie, Australia, after winning the $50,000 Challenger in Adelaide, Australia, during the same week last year.   
   The 6-foot (1.83-meter) left-hander from the San Diego suburb of Poway climbed to a career-high No. 63 last March before battling injuries.
   Klahn reached the second round of the U.S. Open in 2012, beating then-No. 36 Jurgen Melzer of Austria in five sets as a qualifier, and 2013.
