   So much for momentum.
   Sam Querrey, playing his first singles match since upsetting Rafael Nadal to win the Mexican Open in Acapulco on March 4, lost to fellow American and part-time doubles partner Donald Young 6-3, 3-6, 6-3 on Sunday in the second round of the BNP Paribas Open at Indian Wells.
   The 6-foot-6 (1.98-meter) Querrey, seeded 23rd, received a first-round bye. The 29-year-old San Francisco native ousted four top-20 players in succession in Acapulco: No. 11 David Goffin of Belgium, No. 9 and defending champion Dominic Thiem of Austria, No. 17 Nick Kyrgios of Australia and No. 6 Nadal.
   Querrey and Young shocked defending champions Jamie Murray and Bruno Soares in the first round of the Australian Open in January en route to the round of 16.
   Querrey is playing with Gilles Muller of Luxembourg in the BNP Paribas Open; Young is not playing doubles at Indian Wells.
   Young, who stunned Andy Murray in the second round at Indian Wells in 2011 as a qualifier, continued his strong play this year. The 27-year-old left-hander reached the semifinals in Memphis and Delray Beach in consecutive weeks last month.
   Facing tall players doesn't seem to bother the 6-foot (1.83-meter) Young. He also defeated 6-foot-11 (2.11-meter) Reilly Opelka and 6-foot-10 (2.08-meter) John Isner back to back indoors in Memphis and 6-foot-11 Ivo Karlovic in the first round outdoors in Delray Beach.
   Young will face 14th-seeded Lucas Pouille of France. Pouille, 23, reached the quarterfinals at Wimbledon and the U.S. Open last year, stunning Nadal in the round of 16 at Flushing Meadows.
   Taylor Fritz, a 19-year-old wild card from Southern California, shocked Marin Cilic, seeded sixth and ranked seventh, 4-6, 7-5, 6-4 at Indian Wells for his first victory over a top-10 player.
   Fritz, who won the 2015 Sacramento Challenger at 17 for his first pro title, will play unseeded Malek Jaziri of Tunisia. Jaziri, 33, surprised 32nd-seeded Marcel Granollers of Spain 7-5, 6-3.
   Nick Kyrgios and Nenad Zimonjic upset former Stanford stars Bob and Mike Bryan, the No. 2 seeds and two-time champions, 6-4, 3-6 [10-7] in the first round on Saturday.
   Zimonjic, a 40-year-old Serb, has won 54 tour-level doubles titles. He and Daniel Nestor advanced to the Indian Wells final twice, losing to Israelis Jonathan Erlich and Andy Ram in 2008 and Spaniards Marc Lopez and Nadal in 2010.
