   Former Stanford All-American Kristie Ahn jumped 79 places to No. 559 in the world, according to the latest WTA rankings released Monday.  

   The injury-prone Ahn, 22, moved up by reaching the quarterfinals of last month's $25,000 Challenger in Plantation, Fla., on clay as a qualifier before losing to eventual champion Sachia Vickery.

   At 16, Ahn qualified for the 2008 U.S. Open in women's singles before losing to Dinara Safina 6-3, 6-4 in the first round. Safina was ranked seventh at the time and reached No. 1 the following year.

   The 5-foot-5 (1.65-meter) Ahn, from Upper Saddle River, N.J., advanced to the semifinals of the $25,000 Redding Challenger as a qualifier in 2012 and the quarterfinals there last year.
   Ahn gave Stanford the 2013 NCAA team title, winning the deciding match in a 4-3 victory over Texas A&M in the final. She completed her eligibility last May after helping the Cardinal reach the NCAA semifinals and advancing to the round of 16 in singles.
