   Modesto product Maria Sanchez improved 13 places to a career-high No. 90 in the world in doubles after winning the Vancouver Challenger last week with Asia Muhammad. 
   It was the second doubles title of the year for Sanchez, 24, and ended a four-match losing streak in Challenger finals, including Sacramento last month. She won her first career WTA crown in singles or doubles in January, teaming with Sharon Fichman of Canada in Auckland.
   The 5-foot-10 (1.78-meter) Sanchez paired with Muhammad, a 23-year-old former member of the defunct Sacramento Capitals in World TeamTennis, for the first time since they reached the Yakima (Wash.) semifinals in July 2013.
   Also that month, Sanchez climbed to a career-high No. 107 in singles. She has plummeted to No. 321 but advanced to the quarterfinals of last month's Carson and Lexington Challengers, the latter as a qualifier, before falling in the first round in Vancouver to Romina Oprandi of Switzerland. Oprandi is ranked No. 157 after ascending to a career-high No. 32 in June 2013.
   Sanchez was named the 2011 Pacific-10 Conference Women's Player of the Year as a senior at USC.
