Arizona Diamondbacks outfielder Corbin Carroll and Baltimore Orioles infielder Gunnar Henderson were unanimous winners of Major League Baseball's 2023 Jackie Robinson Rookie of the Year awards, which were announced Monday.

Carroll is the first player in Diamondbacks history to win the National League honour. Henderson is the seventh Orioles player to take home the American League award, but the first since pitcher Gregg Olson in 1989.

Both players received 30 first-place votes in balloting from selected members of the Baseball Writers' Association of America.

Carroll was instrumental to the Diamondbacks' surprising 2023 campaign that culminated in the club's first playoff appearance since 2017 and the second World Series trip in franchise history. The speedster produced 25 home runs and 54 stolen bases to become the first rookie with at least 25 homers and 50 steals in a season, and also recorded 116 runs scored, 76 RBIs and a .285 average in 155 regular-season games.

The 23-year-old delivered a solid postseason as well, batting .273 with two homers, 10 RBIs and five stolen bases in 17 games to help Arizona capture its first NL pennant since 2001. 

Henderson also played a key role in his team's unexpected success in 2023, as he led all AL rookies in home runs (28), RBIs (82) and runs scored (100) to help the Orioles to an AL-best 101-61 record and the team's first playoff appearance since 2016. The 22-year-old overcame a slow start to hit .276 with 23 homers, 68 RBIs and an .856 OPS from June 1 on.

A second-round pick of Baltimore in the 2019 draft, Henderson also finished second among AL players with nine triples and ended the season with a .255 average, 10 stolen bases and an .814 OPS in 150 games. He was named the AL's Silver Slugger recipient as a utility player as well after splitting his time between shortstop and third base.

New York Mets pitcher and former Japanese league star Kodai Senga placed second in NL voting with 22 second-place votes and 71 points, with Los Angeles Dodgers outfielder James Outman, Colorado Rockies outfielder Nolan Jones and Cincinnati Reds infielder Matt McClain finishing third through fifth. 

Cleveland Guardians pitcher Tanner Bibee finished second behind Henderson in voting with 20 second-place votes and 67 points. Boston Red Sox first baseman Triston Casas was third with 25 points, with Texas Rangers third baseman Josh Jung and Houston Astros catcher Yainer Diaz rounding out the top five.
