Diamondbacks' 9-Figure Extension Makes Major League History

The Arizona Diamondbacks have locked up a huge piece of their future, signing one of the top two prospects in all of baseball to a massive $111M extension. 

The eight-year deal for 22-year-old Corbin Carroll is worth a guaranteed $111 million, with a club option for 2031 that would bring the total value to $134M.

As noted by Snakes beat writer Steve Gilbert, who broke the news, the contract is the largest ever signed by a player with less than 100 days of Major League service time (and no foreign playing experience). The Atlanta Braves' Michael Harris II held the previous record of $70M, but he was at the top of the heap for just seven months.

Carroll only has 32 games under his belt in the majors, but the D-Backs saw more than enough to be ready to hitch their wagon to the talented young outfielder. In those 115 plate appearances last September, he batted .260 with an .830 OPS, four HR and 14 RBIs, and an OPS+ of 133, meaning he was 33% better than the average hitter. He had posted a 1.036 OPS in Double-A and Triple-A before his late-season callup.
