Adam Lynn Duvall (born September 4, 1988) is an American professional baseball outfielder who is a free agent.

Adam Lynne Duvall was born on September 4, 1988, in Louisville, Kentucky, to parents Jeana and Alvin.

In 2012, he played for the San Jose Giants where he batted .258 and led all Class A players with 30 home runs[10] along with 100 RBIs.

Duvall spent the 2013 season with the Richmond Flying Squirrels, tallying a .252 average, 17 home runs, and 58 RBIs over 105 games.

[13] In his first MLB game, Duvall hit a home run off Cincinnati Reds pitcher Mike Leake.

On September 28, Duvall homered off San Diego Padres pitcher Tim Stauffer for his first career pinch-hit home run.

[8] The Giants earned a wild card spot with an 88–74 record and eventually won the 2014 World Series over the Kansas City Royals.

[22] In his first full season in the majors, Duvall played in 150 games and posted a .241 batting average, 33 home runs, and 103 RBIs.

On April 18, 2017, Duvall hit his first career grand slam off of Kevin Gausman as the Reds won 9–3 over the Baltimore Orioles.

[23] On July 14, with the bases loaded, Duvall hit his first career walk-off in the 11th inning off of T. J. McFarland of the Diamondbacks to give Cincinnati a 4–3 victory.

[8] On May 9, 2018, Duvall hit his first career walk-off home run off A. J. Ramos against the New York Mets to give the Reds a 2–1 victory.

[25][26] On July 30, 2018, Duvall was traded to the Atlanta Braves in exchange for Lucas Sims, Matt Wisler, and Preston Tucker.

[29] Ozuna's equivalent feat the previous day was the first time a National League player had hit three home runs in a game at Fenway Park.

Duvall and Hudson were members of the Miami Marlins and Washington Nationals, respectively, when the teams faced each other on July 21, 2021.

The Braves–Padres game on that same day had been suspended, and by the time it resumed on September 24, 2021, Hudson had joined the Padres and Duvall the Braves.

[41] In Game 5 of the 2021 World Series, he hit a two-out, first-inning grand slam on the first pitch from starting pitcher Framber Valdez, giving the Braves a 4–0 lead.

[43] At the end of the season, Duvall won the National League Gold Glove Award for right field.

[52] However, this success was short lived, as he was placed on the injured list on April 10 due to a distal radius fracture of his left wrist suffered while trying to make a catch in the prior day's game.
