The oft-maligned USMNT left back, seen here outpacing Chivas USA midfielder Blair Gavin last June, comes over from Dallas in exchange for allocation money, the club announced today.
The 26-year-old joined Dallas in 2009 after stints in Germany and Denmark. The University of Portland product made 27 starts for the Western Conference champions last season.
The Spanish-speaking Pearce has 32 U.S. caps.
Pearce is one of several signings Chivas USA has made in recent weeks in a bid to shore up its defense including central defender Jimmy Conrad, New Zealander Andrew Boyens and defensive midfielder Simon Elliott.
Chivas USA has released three players from preseason camp: Former Cal State Northridge goalkeeper Kevin Guppy, who last year was a pool goalkeeper for the league; Canadian defender Curtis Ushedo, a Supplemental Draft pick; and Norberto Ochoa, 20, who was out of Riverside Poly.
Chivas USA dropped its second consecutive preseason game today, losing 2-0 to Real Salt Lake in Casa Grande, Ariz.
Chivas USA lineup: Sergio Arias (Zach Thornton 60), Jorge Flores (Ante Jazic 60), Eriq Zavaleta (Michael Umaa 60), Andrew Boyens (Jimmy Conrad 60), Jimmy Asprilla (Zarek Valentin 60), Ben Zemanski (John Okafor 60), Guillermo Torres (Chukwudi Chijindu 29, Blair Gavin 60), Mariano Trujillo (Mike Lahoud 60), Jess Padilla (Francisco Mendoza 60), Victor Estupian (Gerson Mayn 60), Alejandro Moreno (Alan Gordon 60)
