Corbin Carroll, Gunnar Henderson win NL, AL ROY unanimously - ESPN

Arizona Diamondbacks outfielder Corbin Carroll and Baltimore Orioles shortstop Gunnar Henderson won the Rookie of the Year Award on Monday, only the fifth time both leagues' winners have been unanimous.

Because both started the season in the major leagues and were ranked among the top 100 prospects in baseball, their teams will receive an additional first-round pick in 2024 as part of the Prospect Promotion Incentive that the players' union pushed for in collective-bargaining negotiations to discourage service-time manipulation.

Carroll, 23, is expected to finish high in National League Most Valuable Player voting that will be revealed Thursday after he hit .285/.362/.506 with 25 home runs and 54 stolen bases, the second most in the major leagues behind NL MVP favorite Ronald Acuña Jr.

The 22-year-old Henderson, who helped lead the Orioles to a 101-61 season and American League East title, rode a combination of power and smooth defense to the award and became the Orioles' first Rookie of the Year since Gregg Olson in 1989.

Cleveland right-hander Tanner Bibee finished second — and, in doing so, received a full year of service time despite debuting in late April — and Boston first baseman Triston Casas was third. New York Mets right-hander Kodai Senga took second in the NL, with Los Angeles Dodgers James Outman locking down third.

The last time both Rookies of the Year took 30 of 30 first-place votes was 2017, when New York Yankees outfielder Aaron Judge and Dodgers first baseman Cody Bellinger won the awards. The other seasons with two unanimous winners were 1997 (Boston's Nomar Garciaparra and Philadelphia's Scott Rolen), 1993 (California's Tim Salmon and Los Angeles' Mike Piazza) and 1987 (Oakland's Mark McGwire and San
