GALAXY: Arena drops three from camp

The Galaxy made their first cuts of preseason Monday, releasing second-year defenders Ryan Thomas and Dustin McCarty and dropping supplemental draft Stephen Posa from camp.

Thomas, out of Stanford, and McCarty, from North Carolina, were supplemental picks in 2011. They were the least-used rookies last year and faced an uphill fight to make this year's roster, with head coach Bruce Arena bulking his list to 37 players, including non-contracted invitees, with room for no more than 30 as of March 1.

Thomas (Claremont/Claremont HS), a left back who played on the left side of midfield in two game appearances this preseason, saw action in one Major League Soccer match as a rookie, playing the final 13 minutes in L.A.'s loss at Houston in the Oct. 23 regular-season finale. He also appeared in friendlies against Real Madrid and the Philippines' national team and scored a goal with an assist in eight MLS Reserve League starts.

McCarty, the younger brother of New York Red Bulls midfielder (and sometimes-U.S. national-teamer) Dax McCarty, played in friendlies against Manchester City and the Philippines and in eight MLS Reserve League matches. He had played in two of the Galaxy's three preseason games after dealing with a hamstring injury at the start of camp.

Posa lost a numbers battle in an increasingly deep and dynamic Galaxy attack. The returns of forward Edson Buddle and midfielder Juninho and acquisition of midfielder Kyle Nakazawa, all in the past two weeks, left no room for the San Diego State product. Posa was energetic (and won a penalty kick) in two preseason-game appearances.

The Galaxy has 34 players remaining, and one of the remaining cuts will be of a goalkeeper.

Montreal's reserves will then take on Chivas' reserves in a 45-minute game. Chivas wanted to play 70 minutes. ... Chivas won't have goalkeeper Dan Kennedy, left back Jorge Villafaña and forward Juan Pablo Angel, who are flying Tuesday to Guadalajara. The Goats are unveiling their new uniform on Wednesday's flight back to Los Angeles. ... Galaxy forward Chad Barrett, who switched from No. 11 to his favored No. 19 when Juninho left for São Paulo, has given 19 back to Juninho now that the Brazilian midfielder has returned. Pat Noonan has No. 11, so Barrett will wear No. 9.
