"The Big Mac" admitted to using steroids as early as the 1989 season in which he and Jose Canseco led the Oakland A's to a World Series championship; the second of three straight appearances. During the 1987 season, his rookie year, McGwire shattered the rookie HR record (38) set by Frank Robinson and Wally Berger with 49 HRs; a record that stood for 31 years. According to Mark, he used PEDs on and off from 1989 until his retirement in 2001, which explains him not ever having a neck. Most importantly, he used them during his historic 1998 season when he demolished Roger Maris' HR record with 70 homers and followed it up in 1999 with 65 HRs. McGwire wants us to believe he juiced only for health reasons and not for power, which is a crock of shit. Canseco said he injected Mark in the A's clubhouse in his book, Juiced, back in the days when they were the "Bash Brothers" hitting every baseball and hot Cali blonde in sight. But, of course, Mark denied it. PEDs aside, McGwire was a borderline Hall of Famer until the 1998 and 1999 seasons. If he would've played clean, those two seasons would've put him over the top. He sits tenth in HRs (583) and eighth in slugging percentage (.588) all-time.
