The San Jose Earthquakes signed 2012 MLS All- Star defender Justin Morrow to a new contract Thursday. Per league and team policy, terms of the deal were not disclosed.

Morrow, 25, has played the full 90 minutes in 30 of his club's 31 matches this season. He has one goal and four assists, playing at left and center back. He played 56 minutes in the All-Star Game, a 3-2 win over Chelsea.

"Justin is part of a great young nucleus that we have in San Jose right now and we want to keep that group together," said Earthquakes general manager John Doyle. "Justin has really come into his own this year. He's a hard worker with good character and has all the attributes to have a long and successful career in MLS."

Morrow was originally selected by San Jose in the 2010 MLS SuperDraft, and has played 42 times for the club. He has helped the Earthquakes to the best record in MLS this season, with just a few weeks remaining in the regular season.

"Justin is a great example of a player who continues to work and develop and he can become one of the top defenders in our league because of it," said Earthquakes coach Frank Yallop. "He's an athletic player with tons of pace who has added some assists to his count this season."
