This list reflects some of the changes in performance, health and tools of top prospects throughout the minors, and includes any player currently signed to a pro contract -- so recent draftees and July 2 signings are eligible. This will be my last rankings update until I publish a new top 100 ranking in January as part of the annual offseason prospect package.
