While they have yet to win on the road this season, the Portland Timbers have been very effective in recent home games. The Timbers, though, appear to face a challenging task as they attempt to match their longest unbeaten run at Jeld-Wen Field.

That's because the San Jose Earthquakes, owners of the most points and road victories in MLS, can secure their longest win streak in league play in nearly seven years Tuesday night.

The Timbers (4-7-4) have gone 3-0-2 in their last five at home, but an 0-5-2 road record has kept them from making a move up the Western Conference standings.

After celebrating their first-ever win over rival Seattle on June 24, the Timbers were routed 3-0 at Colorado on Saturday.

"We've got a quick turnaround for San Jose, got to focus and try to get the confidence a little bit higher again and get ready to play," coach John Spencer said.

Spencer's team will almost certainly need a better performance if it wants to match its six-game home unbeaten streak from July 30-Sept. 21, which ended after a draw with San Jose.

The Earthquakes (11-3-3) top the league with 36 points and a 6-2-1 road record. San Jose won its third straight Saturday, rallying from a two-goal deficit for a 4-3 victory over Los Angeles.

Chris Wondolowski broke a tie by pushing his league-best goal total to 14, scoring his third in as many games.

"I can't say enough about the fellas we have," coach Frank Yallop told the league's website. "They never seem to quit."

A fourth consecutive victory would give San Jose its longest win streak in MLS play since a franchise-best six-game run Aug. 20-Sept. 21, 2005.

The clubs played to a pair of 1-all ties during Portland's inaugural season. San Jose's Khari Stephenson scored the tying goal in the 70th minute Sept. 21 during his team's lone visit to Jeld-Wen in 2011, and teammate Alan Gordon had the tying one in the 67th minute at home Aug. 6.

Timbers defender Hanyer Mosquera will be serving the last game of a three-game suspension for striking Los Angeles' Jack McBean on June 17.
