Trinidad & Tobago, which travels to Boston to face the United States in a World Cup qualifier June 20, faces Caribbean rival Grenada Thursday in Tunapuna in a Hexaginal warmup. T&T coach Ian Porterfield called in defender Avery John, older brother of Stern John and a member of the Boston Bulldogs (D3). The only other foreign-based player is England-based goalkeeper Clayton Ince. The Soca Warriors’ squad: Clayton Ince, Michael McComie, Avery John, Stokely Mason, Nigel Pierre, Angus Eve, Arnold Dwarika, Brent Rahim, Dale Saunders, Cyd Gray, Derek King, Reynold Carrington, Anton Pierre, Marlon Cayonne, Claude Adams, Jason Scotland, Sherman Phillip, Trent Noel. ò T&T is looking into suiting up English-born striker Bobby Zamora for the Copa Caribe later in May. Zamora had 23 league goals to lead Brighton to the English Third Division title. ò UConn star Brent Rahim plans on remaining in Trinidad instead of signing with MLS’s Los Angeles Galaxy. He will play for Joe Public.
