[MLS] In the first full Saturday of MLS games, American internationals – former and current – played major roles.

Charlie Davies scored twice in his MLS debut, fueling a 3-1 D.C. United win over struggling Columbus, which lost twice to Real Salt Lake in the Concacaf Champions League and didn’t look much better at RFK Stadium. Teenager Juan Agudelo, who might be paired with Davies some day on the U.S. front line, scored the only goal in the 70th minute as the Red Bulls downed Seattle, 1-0.

The fitness of Jay DeMerit for Vancouver’s MLS debut against Canadian rival Toronto was in question prior to kickoff, but the U.S. international played the full match as the Whitecaps thrilled a crowd of 22,592 at Empire Field by beating TFC, 4-2.

Kyle Beckerman rifled a shot from the top of the arc that clanged into the net off the inside of the post to give Real Salt Lake 1-0 triumph over San Jose in miserably wet and gusty weather at Buck Shaw Stadium. Goalie Nick Rimando fended off furious assaults by the Quakes in the final 20 minutes to preserve the three points.

Jeff Larentowicz scored the first goal for defending champ Colorado in the Rapids' 3-1 defeat of expansion Portland, which got its goal from Kenny Cooper. Jimmy Conrad scored a goal against his most recent MLS club as Chivas USA began the Robin Fraser Era by losing to Sporting Kansas City, 3-2. Another former U.S. defender, Danny Califf, punched home a goal in a goalmouth scramble by which Philadelphia posted a 1-0 win in Houston.
