SAN DIEGO - Colin Rea is heading back to the San Diego Padres after leaving with an injury in his first start since being traded to Miami.
The Marlins acquired Rea on Friday in a seven-player deal with the Padres, but he had to leave Saturday's game against St. Louis in the fourth inning and was put on the 15-day disabled list with a right elbow sprain.
San Diego announced Monday it reacquired Rea from Miami and sent minor league pitcher Luis Castillo back to the Marlins. Castillo had gone from Miami to San Diego in Friday's deal.
Miami acquired Rea and right-hander Andrew Cashner on Friday as part of a push for a postseason spot, but Rea is of little use to the Marlins if he's hurt.
