Stanford's Gibbs coasts into NCAA semifinals

   Defending champion Nicole Gibbs of Stanford routed fellow No. 9-16 seed Yana Koroleva of Clemson 6-1, 6-1 today in the quarterfinals of the NCAA Championships in Urbana, Ill.
   Gibbs is bidding to become the first back-to-back women's champion since Stanford's Amber Liu in 2003 and 2004. Liu is married to International Tennis Hall of Famer Michael Chang.
   Steve Johnson of USC won the last two men's singles titles before completing his eligibility and turning pro. In the past year, he has improved his world ranking from No. 368 to No. 130.
   Gibbs, a 5-foot-6 (1.68-meter) junior from Santa Monica, will face unseeded Breaunna Addison of Texas in Sunday's semifinals at a time to be announced. The match will be streamed live at www.ncaa.com.
   Addison, a 5-foot-5 (1.65-meter) freshman from Boca Raton, Fla, outlasted seventh-seeded Gina Suarez-Malaguti of North Carolina 5-7, 6-1, 6-4.
  Gibbs will be fresher on Sunday after breezing in the quarters while Addison struggled.
  Texas is coached by Patty Fendick-McCain, a Sacramento native who won the 1986 and 1987 NCAA singles titles while attending Stanford.

   French Open -- Sam Querrey can gain revenge Sunday when he faces Lukas Lacko of Slovakia in the first round in Paris.
   The 18th-seeded Querrey, a San Francisco native and part-time member of the Sacramento Capitals in World TeamTennis, lost to Lacko 7-6 (6), 6-3 in the first round of the 2011 SAP Open in San Jose in their only previous meeting. San Jose is 48 miles (77 kilometers) south of San Francisco.
   Querrey, ranked 20th, is 1-6 lifetime in the French Open. Lacko, ranked 74th, is 1-5 (including qualifying). Lacko's win came in a 2010 marathon: 4-6, 7-6 (5), 7-6 (4), 6-7 (5), 12-10 over Michael Yani of the United States in 4 hours, 56 minutes.
   Yani won the 2008 Yuba City Challenger as a qualifier, beating Sacramento native Sam Warburg in the final. Warburg won the 2004 NCAA doubles title with Stanford teammate KC Corkery.   
   Meanwhile, former Stanford star Mallory Burdette will make her French Open debut Sunday against Donna Vekic of Croatia. Burdette, who turned pro last September, is ranked No. 82. Vekic is No. 79.
   Dmitry Tursunov, a Russian based in the Sacramento suburb of Granite Bay, is scheduled to play 22nd-seeded Alexandr Dolgopolov of Ukraine for the second time in one month on Tuesday or Wednesday. Dolgopolov won 7-6 (2), 7-6 (3) in the second round in Munich three weeks ago to even their head-to-head record at 1-1.
   Maria Sanchez, a Modesto native, and Bradley Klahn, the 2010 NCAA singles champion, lost in qualifying. Sanchez, seeded fourth, fell in the second round and Klahn in the first. Both were making their French Open debut.

   Sunday's matches will be televised live from 2 to 7 a.m. PDT on ESPN2, 7 a.m. to 4 p.m. on Tennis Channel and 9 a.m. to noon on NBC.
