"The Great Giambino" was a power-hitting machine when he played for the A's and was the most coveted free agent after the 2001 season. Naturally, the Yankees came calling and Jason left the poor Oakland A's for the loaded pinstripes for a paltry 7-year/$120-million contract. He was two years removed from an MVP season and had just hit for .342 to go along with 38 HRs and 120 RBIs. He continued his mashing of the baseball with New York smacking 41 homers in each of his first two years in the Bronx. Then it all came crashing down. His name came up during the 2003 BALCO investigation and reports surfaced saying Jason admitted to using steroids to a federal grand jury.

A benign tumor was found on Giambi during the 2004 season and many folks attributed it to past steroid use. Jason returned to form the following two seasons hitting 32 HRs in 2005 and 37 HRs in 2006, respectively. He played the McGwire card and stayed quiet about the PED issue whenever asked by the media until 2007. He finally came clean and told USA Today in May of '07 that he was "wrong for doing that stuff" and stated, "What we should have done a long time ago was stand up — players, ownership, everybody — and said: 'We made a mistake.' He was never the same after that, but he was also 36 and at the tail end of his career.
