Jung stuns No. 2 seed McDonald in S.F. Open

   Jason Jung, a Los Angeles-area native who plays for Taiwan, stunned second-seeded Mackenzie McDonald, a San Francisco Bay Area product, 1-6, 7-6 (3), 6-2 tonight to reach the quarterfinals of the $100,000 Kunal Patel San Francisco Open.
   McDonald, the runner-up to Kei Nishikori last week in Dallas, double-faulted on Jung's second match point in the indoor tournament at the Bay Club SF Tennis Center.
   Jung, 28, graduated from the University of Michigan in political science in 2011 and worked for an oil company in his native Torrance for one month before being laid off. He planned to go to law school but didn't do as well on the admission test as he had hoped, so he launched his professional tennis career.
   Jung, who lost to Nishikori in the Dallas semifinals, will face sixth-seeded Noah Rubin of Long Island, N.Y., in Friday night's late match.
   Rubin, the 2014 Wimbledon boys singles champion, defeated qualifier Jared Hiltzik of Orlando, Fla., 6-1, 6-4.
   In another quarterfinal, San Jose product Dennis Novikov will take on seventh-seeded Filip Peliwo of Canada.
   Novikov, 24, survived his second straight three-setter. He outlasted Daniel Elahi Galan of Colombia 5-7, 6-3, 6-4 after ousting top-seeded Alexander Bublik of Kazakhstan 7-6 (10), 3-6, 6-2 on Tuesday night.
   The 6-foot-4 (1.93-meter), 200-pound (91-kilogram) Novikov pounded 15 aces and committed three double faults against Galan. Novikov won 53 percent of the points on his second serve (19 of 36) to only 36 percent for Galan (12 of 33).
   Peliwo, the 2012 Wimbledon boys singles champion, dismissed wild card Danny Thomas, an 18-year-old left-hander based in Wesley Chapel, Fla.
   Here are the singles and doubles draws and Friday's schedule.
