Jackie Bradley Jr. (born April 19, 1990), nicknamed "JBJ",[1] is an American professional baseball outfielder who is a free agent.

He has previously played in Major League Baseball (MLB) for the Boston Red Sox, Milwaukee Brewers, Toronto Blue Jays, and Kansas City Royals.

Bradley was named Minor League Defensive Player of the Year by the Red Sox organization for the 2012 season.

[7] After an outstanding spring training, on March 31, manager John Farrell announced that Bradley would be the Opening Day left fielder on April 1 at Yankee Stadium.

[13] On March 28, 2014, Bradley was optioned to Triple-A Pawtucket after he was unable to beat Grady Sizemore for the starting center field position, but was recalled three days later after the team placed Shane Victorino on the 15-day disabled list.

Bradley saw regular time as the team's center fielder throughout the 2014 season, appearing in 127 games, but was optioned back to Triple-A Pawtucket on August 18 after hitting just .216, despite playing exceptional defense.

On June 25, he was called up to play right field for the Red Sox while Hanley Ramírez recuperated with a sore wrist.

[15] In a June 30 game against the Toronto Blue Jays pitcher Marco Estrada, Bradley hit his first home run since May 31, 2014.

On August 15, 2015, Bradley became only the eighth player in the modern era with five extra-base hits in one game, recording two home runs and three doubles in six at-bats, in the Red Sox' 22–10 defeat of the Seattle Mariners.

[12] In the postseason, he was 3-for-15 (.200) with a home run and five RBIs,[12] as the Red Sox lost to the Houston Astros in the Division Series.

Bradley was again the everyday center fielder for the Red Sox, and drew national attention for his stellar defense,[22][23][24][25] but struggled at the plate until mid-August.

[24][26] On August 11, in the first game of a day-night doubleheader against the Baltimore Orioles, Bradley homered twice to lift the Red Sox to a 5–0 victory.

[27] For the season, Bradley struggled offensively, hitting .234 with 13 home runs 59 RBIs and 17 stolen bases in 144 games.

In Game 3, he hit a grand slam off of Roberto Osuna in the top of the eighth inning, extending Boston's lead from 4–2 to 8–2, which would prove to be the final score.

In Game 4, he hit a two-run go-ahead home run off of Josh James in the top of the sixth inning, putting the Red Sox up 6–5 en route to an 8–6 final.

[30] Bradley returned to his center field role with Boston in 2019, appearing in 147 games while batting .225 with 21 home runs and 62 RBIs.

[12] He made contact with the lowest percentage of pitches he swung at in the strike zone (76.4%) of all major league batters.

[12] On December 1, 2021, the Brewers traded Bradley, David Hamilton, and Alex Binelas to the Red Sox in exchange for Hunter Renfroe.

[41] Bradley was released by the Red Sox on August 4, becoming a free agent, shortly after the team acquired Tommy Pham and Eric Hosmer.

[45] The agreement came with an invitation to the major league team's spring training, with the expectation that Bradley could provide depth in the outfield following injuries to Drew Waters and Diego Hernández.

[46] He played in 43 total games for Kansas City, but limped to a .133/.188/.210 slash line with one home run and six RBIs.
