Brian Carroll's quiet efficiency in D.C. United's defensive midfield has caught the attention of U.S. national team coach Bruce Arena.

Carroll, a former All-Met at West Springfield High School, and United teammate Santino Quaranta have been called up to the national team for upcoming World Cup qualifiers. An official roster announcement isn't expected until early next week, when U.S. camp opens in Miami.

Quaranta will be available for both the Oct. 8 match at Costa Rica and the Oct. 12 game against Panama in Foxboro, Mass., while Carroll will be in uniform for the Panama game only.

Since the U.S. team has already clinched a World Cup berth, Arena plans to test several young players in the remaining qualifiers in an effort to identify roster candidates for next year's tournament in Germany. Only a few European-based players have been invited for these two games.

As a result of the call-up, Quaranta will miss both United matches next week -- Wednesday at Salt Lake City and Oct. 8 against the MetroStars at RFK Stadium. Carroll, however, won't miss either MLS game because he is not scheduled to join the U.S. team until three days before the Panama match.

While Quaranta, a 20-year-old forward-midfielder from Baltimore, has become a regular on the U.S. squad, Carroll, 24, has never made an appearance. (He did play for the U.S. under-20 and under-23 national teams.)

After not appearing in an MLS regular season match as a rookie in 2003, the former Wake Forest standout has played in 58 consecutive games (52 starts) for United. This year he has one goal and three assists, and leads the team in minutes played with 2,256.

United (14-9-5) will play the MetroStars (10-8-10) tomorrow night at Giants Stadium. With a victory, D.C. would clinch a berth in the playoffs, which are scheduled to begin Oct. 22.

Soccer Notes: English Premier League club Bolton, in its inaugural campaign in European competition, defeated Bulgaria's Lokomotiv Plovdiv, 2-1, to reach the group stage of the UEFA Cup.

Bolton, which advanced 4-2 on aggregate over two matches, trailed 1-0 in Bourgas, Bulgaria, before an own goal tied it in the 79th minute. Kevin Nolan then scored with four minutes left. . . .

Manchester United captain Roy Keane doesn't think he'll get a contract extension to return next season. "I would like to play another year or two, but I do not think it will be at Manchester United," he said on the club's television station, MUTV. . . .

Herculez Gomez scored midway through the first half to give the Los Angeles Galaxy its second U.S. Open Cup championship with a 1-0 victory over FC Dallas late Wednesday in Carson, Calif.
