The Arizona Diamondbacks and top prospect Corbin Carroll have agreed to an eight-year contract extension, according to multiple reports.

The 22-year-old outfielder signed for a base compensation of $111million, with a team option and escalators that could raise the total value of the deal over $134m.

According to MLB.com, Carroll's compensation is the most ever given to a U.S.-based player with fewer than 100 days of major league service time.

The previous record of $70m had been set by the Atlanta Braves' Michael Harris, who went on to be named the 2022 NL Rookie of the Year.

The deal locks Carroll up for all of his arbitration-eligible seasons, plus at least his first two free agency seasons.

Arizona drafted Carroll in the first round of the 2019 draft, and the left-handed center fielder has remained among the highest-ranked prospects in the organisation ever since.

Carroll made his major league debut last season, batting .260 with an .830 OPS in 115 plate appearances. In 32 games he had 27 hits, 15 for extra bases.

Earlier this offseason, MLB.com ranked the speedy outfielder as the No. 2 prospect in baseball, behind Baltimore Orioles infielder Gunnar Henderson.
