   Former Stanford star Bradley Klahn dropped 24 spots to No. 116 in the world on Monday after sitting out last week.
   Klahn won his first Challenger singles title in Aptos during the corresponding week last year, and his ranking points fell off the computer. The rankings are based on a revolving 52-week system. 
   Klahn, a 23-year-old left-hander from the San Diego suburb of Poway, has not played since defaulting his singles quarterfinal and doubles semifinal with a foot injury on July 19 in the Binghamton (N.Y.) Challenger.
   But Klahn, who reached a career-high No. 63 in March, tweeted that he's "good to go" for the upcoming U.S. Open.
   At Stanford, Klahn captured the 2010 NCAA singles title as a sophomore, underwent surgery for a herniated disc as a junior and graduated in economics in 2012.
