Ivan Calderon Perez (March 19, 1962 - December 27, 2003), better known as Ivan Calderon, was a Puerto Rican Major League Baseball player from 1984 to 1993 and was named an All-Star in 1991. He was murdered December 27, 2003 in a bar in Loiza, Puerto Rico. Shot five to seven times in the head, he died instantly. Local police suspect mafia involvement in the murder.
He was signed by the Seattle Mariners as an amateur free agent July 30, 1979 and made his Major League debut with the team August 10, 1984. Midway through the 1986 season the Mariners traded him to the Chicago White Sox, where he became an every day rightfielder in 1987.
Known for his power and speed, he put together a series of productive seasons in Chicago. The team traded him, however, after the 1990 season to the Montreal Expos in a deal that brought Tim Raines to the White Sox.
The Expos raised his yearly salary to over US$2 million a season, and his efforts were rewarded with a place on the National League All-Star team. Injuries the following season, however, slowed him down, and after stints with the Boston Red Sox and again with the White Sox, Calderon was finished in baseball, at the age of 31.
