The three defenders (Damien Perrinelle, Andrew Jean-Baptiste, and Ronald Zubar) have varying levels of experience with the team and the league.
Perrinelle, 31, spent a portion of 2014 with the Red Bulls, making a handful of appearances with the team in MLS and the CONCACAF Champions League before the club declined his option at the end of last season.
Andrew Jean Baptiste, 22, is a native of Brooklyn with three years of MLS experience; two with the Portland Timbers and one with Chivas USA. A central defender, Jean-Baptiste has made 41 appearances in the MLS regular season.
The most well-known of the trio may be the 29-year-old Zubar, a former French youth international that has played in Ligue 1 with Marseille and the English Premier League with Wolves. He comes to the Red Bulls from Ligue 1 club Ajaccio, with which he made 38 appearances and scored two goals.
