Toronto FC added four new players Wednesday to itsroster for its inaugural Major League Soccer season.

The expansion team, which begins MLS play when the season opens in the spring,introduced defenders Adam Braz, Chris Pozniak and Marco Reda along with Irish midfielder Ronnie O'Brien at a news conferencein Toronto's CN Tower.

"We're excited with our Canadian signings," head coach Mo Johnston said."Adam, Chris and Marco are all versatile players with international experience. They will make fantastic additions to our team."

Braz and Pozniak, both 25, and Reda, 29, have played for the Canadian national team.

O'Brien, 27, is a two-time MLS all-star, playing with Dallas from 2002 to 2006.

"We believe Ronnie is the best right-footed player in the league," said Johnston. "He is an exceptional player and we worked hard to acquire him."

The four join Canadian midfielder Jim Brennan, Toronto FC's first signing.

Johnston picked former Houston Dynamo midfielder Adrian Serioux in last Friday's expansion draft, but then traded the Canadian national team member to Dallas FC along with a second-round draft pick for O'Brien.

He also dealt midfielder Tom Regan to Red Bull New York for forward Edson Buddle.

Toronto FC joined Major League Soccer on May 11 as its 13th team and the first outside the United States.
