Defending champ withdraws from Redding Challenger

   Third seed and defending champion Julia Boserup on Tuesday withdrew from the $25,000 USTA Oak River Rehab Challenger in Redding, Calif.  
   Boserup, 21, of Newport Beach, Calif., suffered an undisclosed injury while practicing at the Sun Oaks Racquet Club, tournament supervisor Billie Lipp said.
   Replacing Boserup in the draw is Kristy Frilling, a doubles All-American as a senior at Notre Dame last season. Frilling, from Sidney, Ohio, is scheduled to meet Keren Shlomo of Israel today at 10 a.m. in the opening round.
   Meanwhile, Allie Will continued her Redding success. A semifinalist last year as a University of Florida junior, Will upset fifth-seeded Adriana Perez of Venezuela 4-6, 6-4, 6-2 in the first round.
   The 5-foot-10 Will, who has led Florida to the last two NCAA championships, will face qualifier Macall Harkins on Thursday in the second round. Harkins, a 26-year-old former TCU star from Palos Verdes in the Los Angeles area, routed Caroline Doyle, a 16-year-old wild card from San Francisco, 6-2, 6-1.
   Also advancing as a qualifier was Chelsey Gullickson, who won the 2010 NCAA singles title on her home courts as a University of Georgia sophomore. Gullickson, the daughter of former major-league pitcher Bill Gullickson and a resident of Palm Beach Gardens, Fla., outlasted Romana Tedjakusuma, a 36-year-old Indonesian living in Tracy, Calif., 6-4, 1-6, 6-4.
  Top-seeded Florencia Molinero, an Argentine ranked No. 199 in the world, is set to play qualifier Kristie Ahn, a Stanford junior, in the opening round today after a 10 a.m. match. Second-seeded Veronica Cepede Royg of Paraguay is scheduled to face Klara Fabikova in the first round at 10 a.m.
   Grand Slam singles champions Victoria Azarenka and Samantha Stosur played one year each in Redding as teenagers.
   Azarenka, the reigning Australian Open titlist, reached the singles quarterfinals at 15 in 2005 and did not play doubles. Stosur, last year's U.S. Open winner, lost in the first round of singles and advanced to the doubles semifinals at 18 in 2003.
   Admission to the tournament is free.
