Baseball's pharmacy hall of fame

Dodgers left fielder Manny Ramirez will be going through uncharted territory when he returns to the lineup today after serving a 50-game suspension for testing positive for a banned substance. Phillies reliever J.C. Romero returned from his suspension June 3, but Ramirez is the first high-profile player to serve time under MLB's drug testing policy. Below is a look at six players who were publicly linked to performance-enhancing drugs, and how they fared afterward.

Barry Bonds

Position: LF

How it went down: In December 2004, the San Francisco Chronicle reported that Bonds testified before a BALCO grand jury in December 2003 that he used substances that he believed were an arthritis balm and flaxseed oil, but were actually an anabolic steroid and THG. In March 2006, the book "Game of Shadows" documented Bond's testimony and his use of performance-enhancing drugs while playing with the San Francisco Giants, including human growth hormone. Bonds has never apologized for or admitted such use, and was indicted on charges of perjury and obstruction of justice on Nov. 15, 2007.

How he fared on the field: Bonds' next two seasons with the Giants entailed chasing the all-time home run record, first passing Babe Ruth's 714 on May 28, 2006, and then surpassing Hank Aaron's mark of 755 on Aug. 7, 2007. After batting at least .300 from 2000 to 2004, Bonds never reached that mark in his last three seasons of his career, including dropping from .362 in 2004 to .286 in 2005.

Paul Lo Duca

Position: Catcher

How it went down: On Dec. 13, 2007, Lo Duca was cited in the Mitchell Report as a user of steroids and human growth hormone. He was also accused of referring former Dodgers teammates Eric Gagne and Kevin Brown to his drug supplier. Upon his arrival with the Washington Nationals on Feb. 17, 2008, Lo Duca issued a statement in which he apologized for "mistakes in judgment," but he did not say what those mistakes entailed.

How he fared on the field: Lo Duca started the 2008 season in Washington as the team's least productive batter, hitting .200 in 50 at-bats. He then fractured his right hand and went on the disabled list from early May to mid-June. The Nationals released him July 31, 2008, after he batted .230 with no home runs and 12 runs batted in in 139 at-bats. The Florida Marlins picked Lo Duca up in a minor league deal on Aug. 8 and he was called up eight days later, hitting .294 with three RBIs in 34 at-bats. He became a free agent after the season and remains unsigned.
