Antonio Martinez scored in his first game for Los Angeles since arriving via a multi-player trade from Dallas. The 26-year-old, who was born in Carson, Calif., celebrated his homecoming by chipping Crew keeper Tom Presthus just before halftime in the Galaxy's 2-1 win.
Alexi Lalas scored on a header from a Simon Elliott free kick before Columbus notched a late goal through Brian Maisonneuve.
