Despite six saves by Busch, the Earthquakes (5-6-8) extended their winless streak to six games (0-2-4). Hesmer had five saves for the Crew (7-5-7), who have four wins, two losses and a tie over the past seven games.
Hesmer parried a header by Chris Wondolowski over the crossbar in the 75th minute, just after Busch denied a break by Andres Mendoza. Busch also slid to the right of the goal to stop Justin Meram in the 90th minute.
San Jose was blanked for the fifth time in six games, while Hesmer recorded his second straight shutout and seventh of the season.
