SANTA CLARA, Calif. (AP) -- Chris Wondolowski scored his MLS-leading 26th goal and the San Jose Earthquakes came back twice in the second half for a 2-2 tie with the Los Angeles Galaxy on Sunday.
Wondolowski's goal, a diving header in the 73rd minute off Marvin Chavez's corner kick, put him one behind Roy Lassiter's season MLS scoring mark with one game left.
The Earthquakes (19-6-8), who clinched the Supporters' Shield when Sporting Kansas City tied New York on Saturday, finish their regular season Saturday in Portland.
Wondolowski moved into a tie for second place on the league's goal list. Stern John had 26 goals for Columbus in 1998, and Mamadou Diallo accomplished the feat for Tampa Bay in 2000.
Robbie Keane scored his 12th goal in 15 games, and Edson Buddle, making his first start since May 26, nodded in his third of the season to stake the Galaxy to a pair of second-half leads.
But Marvin Chavez curled home a beautiful free kick, and Wondolowski finally broke through after hitting the post twice in successive minutes earlier in the second half.
San Jose extended its unbeaten streak at Buck Shaw Stadium to 18 matches, moving to 11-0-7 since Aug. 13, 2011. The Earthquakes are unbeaten in eight matches overall.
The Galaxy (15-12-6) are virtually assured of finishing fourth in the Western Conference, and thus having to play an extra postseason match.
Los Angeles outshot San Jose 11-2 in the first half, carving up San Jose's defense with threaded through balls. Christian Wilhelmsson's ninth-minute toe-poke beat goalkeeper Jon Busch but rolled just wide. Busch charged off his line to make saves against Buddle in the 22nd minute and Keane in the 27th.
Wondolowski hit the post with a left-footed shot from 22 yards in the 49th minute, then banged an open back-post header from a corner kick off the woodwork the following minute.
San Jose had three chances but couldn't score in a wild 51st-minute goalmouth scramble.
The Galaxy grabbed back the momentum in the 59th with a play started and finished by Keane. The Irish international sprung Buddle loose on the left wing, and the return cross bounced off two Earthquakes defenders and dropped down for Keane to jam home at the edge of the 6-yard box.
San Jose responded in the 61st minute with a beautiful 25-yard free kick from Chavez, who bent his effort over the wall and tucked it just inside the near post.
Buddle outjumped Victor Bernardez in the 69th minute to knock home a relatively simple header off Sean Franklin's deep right-wing cross.
But the Quakes tied things up with another set-piece strike in the 73rd minute. Chavez delivered a corner into a seething Galaxy box, where Wondolowski conjured up a diving header for his eighth goal in six games.
