Manny Ramirez acknowledged that he has made many mistakes in his life and seeks a new chance to show that he has changed. Ramirez said it was a mistake to have used banned performance-enhancing substances and to retire without providing any explanation to fans last April. "Every day that goes by I regret the decisions I made by following bad advice," Ramirez said. "We are human, we make mistakes, we are not perfect. Everybody deserves a chance to show he has changed." Ramirez, a lifetime .312 hitter with 555 homers and 1,831 RBIs over 19 seasons with Cleveland, Boston, Los Angeles, the White Sox and Tampa Bay, was reinstated by Major League Baseball from the voluntary retirement list to the free agent list on Saturday.
