Bret Boone Former MLB player​ April 6, 1969) is a former Major League Baseball second baseman. During his career Boone was a three-time All-Star, four-time Gold Glove winner, and two-time Silver Slugger Award winner. He is a member of the Boone family, one of the most recognizable families in baseball.

Boone started his playing career with the Seattle Mariners where he set the club record for home runs in a season by second baseman in 1993 (12 in 76 games)[3] but was traded that same year to the Cincinnati Reds along with Erik Hanson.

In 2001 Boone returned to the Seattle Mariners, the organization with which he came up from 1990 to 1993.[4] Now an All-Star—having averaged 21 home runs a year from 1998 through 2000, twice reaching a career high in doubles (at 38, in 1998 and 1999) -- Boone's superior play continued as he led the league in runs batted in (141), while producing a batting average of (.331). He also broke the Mariners' team record of home runs for a second baseman with his 37 home runs while hitting 37 doubles.

Boone started in the All Star Game in Seattle, received a Silver Slugger Award and finished third in the AL MVP voting. His Mariners paced the league with a record 116 wins, earning the AL West championship and advancing to the ALCS, tying the all-time team record for wins in a season with the 1906 Chicago Cubs.

The following year Boone won a Gold Glove for his defense and continued to show the power he had demonstrated the previous years, hitting 24 home runs with 34 doubles. On May 2, 2002, Boone and teammate Mike Cameron became the first teammates to each hit two home runs in a single inning, doing so in the first inning against the White Sox.

With local media and behind the scenes he was famous for his humorous behavior. Boone took up not one but three lockers, as Erick Walker notes, "one for him, another with a nameplate above that read 'Boone's friend' and a third with a nameplate that read 'Boone's friend's friend' that was scattered with about 100 bats.
