2021 Top 100 Prospects, Brought To You By Rapsodo
Baseball America's final significant in-season Top 100 update is here, accounting for considerable performances changes and new information gathered since our comprehensive updated at the midpoint of the 2021 season.
Today's update includes four new pitchers near the back of the list from the Rays, Twins, D-backs and Mariners organizations.
The lost 2020 season of a year ago created a challenging environment to assess prospects, particularly deciphering whether gains made at alternate training sites and instructional league camps would hold under the rigors of a full season. The 2021 season has done an excellent job filtering out which steps forward were real and which were fleeting hot streaks.
You will also find updated capsules for a number of players, taking in-season production or new injury information into account where applicable.
The Top 100 is brought to you by Rapsodo. Rapsodo develops data-driven sports technologies designed to empower athletes and coaches to cost-effectively analyze and improve their game. All 30 MLB teams and over 1,200 colleges and facilities use Rapsodo data as a measuring stick for player development and evaluation.

Tools: Hit: 55 | Power: 60 | Run: 40 | Fielding: 55 | Arm: 50
Skinny: Casas is one of Boston's cornerstones for the future as he has preternatural hitting ability to go with his impressive power. He's a potential impact hitter who could hit 30-plus home runs in the middle of their lineup.More Less

Tools: Hit: 65 | Power: 55 | Run: 40 | Field: 60 | Arm: 60
Skinny: Mayer doesn’t run all that well, but that’s pretty much the entire laundry list of what he struggles to do. He’s a smooth defender at shortstop with a big arm and should hit for both power and average.More Less

Tools: Hit: 55 | Power: 45 | Run: 70 | Fielding: 50 | Arm: 45
Skinny: The questions with Duran coming out of the 2018 draft mostly revolved around whether he would develop much in the way of power. The Red Sox made some alterations to his swing last summer at the alternate site and he responded by showing more juice in games. Despite a rocky major league debut, that extra power from a player who can play center field could add up to a very enticing player.More Less

Skinny: One of biggest wild cards of the 2020 draft has come up aces for the Red Sox. In his first season as a pro, Yorke has showed as-advertised hittability and burgeoning power. Combined, his tools have carried him through the lower levels of the minor leagues and opened the eyes of evaluators along the way.More Less
