Here is a pretty good profile...

1989: In his second season as a Brewer, Sheffield is the Opening Day starter at shortstop - his favorite position. But after missing games due to injuries, he loses his starting shortstop position to Bill Spiers, and upon returning, is asked to play third base (which doesn't sit well with the 20-year-old). Sheffield considers the Spiers promotion "race-related" (Spiers is white) and talks to the press about it. He also criticizes his team's own pitchers for not retaliating against other clubs' pitchers who throw inside to him.
1991: Sheffield hits. 294 with 67 RBIs in 487 at-bats for Milwaukee: his best season up to this point.
1992: Sheffield is traded to the San Diego Padres for three prospects. He tells San Diego reporters that he "feels like he's out of prison" now that he's out of Milwaukee. Now playing in the National League, Sheffield faces Gooden (a pitcher for the NY Mets) for the first time, and goes 1-for-3. Sheff would finish '92 with career bests in average (.330), homers (33) and RBIs (100), but the Padres struuggle on the field and suffer financial problems.
1993: Money plays a part in Sheffield being traded to the Florida Marlins, an expansion team. Sheff is dealt for a minor-league pitcher named Trevor Hoffman, who would become an All-Star closer for the Padres.
1995: Just a few days after the season, Sheffield is grazed by a bullet while driving in Belmont Heights. People wonder if the shooting is the result of Sheffield's questionable friend selection.
1997: Sheffield's four-year-old Marlins become the youngest team to win a World Series, beating Cleveland in seven games. Shortly thereafter, financially-strapped team owner Wayne Huzienga sells most of his top players, including Sheffield, who ends up in Los Angeles with the Dodgers. After the season, he meets gospel singer DeLeon Richards in a hotel lobby, and marries her one year later.
2000-2001: Gary complains that the Dodgers are spending their money unwisely, and tells team management he wants to be traded. He goes to the press and insults teammates, including pitchers Kevin Brown and Darren Drefoirt. On Brown: "They're paying Brownie $15 million a year until he's 41." On Dreifort: "They just gave Dreifort $55 million when he's only won 39 games in his career."
2002: Sheffield joins the Atlanta Braves, and tells the press "he wants to go to the Hall of Fame as a Brave." He hits 25 homers, drives in 87 runs and bats .307 (his worst season in three years).
2004: Sheffield signs with the New York Yankees, joining a team of superstars led by Derek jeter, Japanese legend Hideki Matsui, and another newcomer - Alex Rodriguez. During the season, Sheffield's name surfaces in a steroids scandal involving a California lab, San Francisco superstar Barry Bonds, and other players. That is followed by a videotape sex scandal involving his wife, singer R Kelly, another woman and a $20,000 extortion attempt by a self-proclaimed minister.
2005: Sheffield, considered a clubhouse leader in his first year with the Yanks, starts Spring Training '05 on the wrong foot by first calling teammate Jason Giambi a "crybaby," and then telling the media he wants out of New York when his contracts expires after the '06 season.
also the intentional error thing:
According to a post at Bronx Banter, the Sheffield quote appeared in the Los Angeles Times on September 1, 1992. About his time in Milwaukee, Sheffield said:
The Brewers brought out the hate in me. I was a crazy man. ... I hated everything about the place. If the official scorer gave me an error, I didn't think was an error, I'd say, 'OK, here's a real error,' and I'd throw the next ball into the stands on purpose.
Needless to say, as Brewer Fan, I have always hated him.
