The league is using the machine to evaluate umpires.

The umpires' union has charged that officials violated the labor agreement by using pitch counts to evaluate umpires.

The union maintained that QuesTec could not evaluate umpires fairly or accurately.

As of 2010, Forman was still involved with baseball, evaluating umpires in the Coastal Plain League.

The commissioner's office, the lawyers continued, is evaluating umpires on criteria "that are unrelated to the job and the game of baseball."

The grievance, Gibson said, was based on baseball's use of technology to evaluate umpires.

Gibson also questioned the way the system has been used in evaluating umpires.

The system, the union added, "misreads pitches high, low, inside and outside" and "is just not good enough to be used to evaluate professional umpires."

This is about the legitimacy of using pitch counts of umpires to evaluate umpires.

They further argue that the system should not be used to evaluate umpires or rank them for All-Star Game and postseason assignments.
