BOSTON -- The Red Sox and Major League Baseball officials are planning tight security in Florida Monday when Boston plays the Devil Rays after the team received a threat against the club's black and Latin players.

The team received a threat mailed from the Memphis, Tenn., area targeting the players and citing at least two by name, the Boston Herald reported.

Police are searching for a suspect believed to originally be from the Baltimore area but now living near Memphis.

The players were warned about the threats and will likely have extra security for the games at Tropicana Field in St. Petersburg, Fla.

The Sox are sending some of the team's top security officials as is MLB and both the FBI and local law enforcement officials in Florida have been advised of the threat.

The team is scheduled to play the D-Rays Monday through Wednesday, but the threat is not believed to be related to the recent brawls between Sox and D-Rays players which erupted earlier in June.

Red Sox officials declined to comment about the threat report.
