From the DDN:

Wednesday night, Pierson was fired by Reds farm director Johnny Almaraz.

“Johnny told me I was too negative,” Pierson said.

Almaraz said Thursday that he had been thinking about the move for a while.

“We’re committed to making the players the best they can be,” he said. “We want to develop major leaguers, and we felt a change was needed.”

That’s vague enough not to mean anything.

New pitching coach Pete Magre, a recent hire by the organization, is expected to be in place tonight.

Magre, from San Antonio, was pitching coach at Division II Incarnate Ward College before signing with the Reds to help pitchers at the organization’s rookie Gulf Coast League club in Sarasota, Fla.

“He pitched for the Reds in the minor leagues 10-12 years ago and he’s got a lot of energy,” Reds minor-league pitching coordinator Mack Jenkins said

Dragons manager Billy Gardner Jr. said he thought Pierson, “did a good job,” and “helped the pitchers get better,” but was not consulted on the move.

This summer, the Dragons rank 11th (out of 14) in team ERA at 3.92. Four pitchers from this year’s staff were promoted after working with Pierson, including Johnny Cueto, Blake Hendley, Justin Mallett and Zac Stott.

And he worked with Homer Bailey last year.

Does bring up an interesting question though…is team ERA a good way to judge the effectiveness of a minor league pitching coach or is the number of his charges being promoted a better way of judging?

It is also another example of Wayne Krivsky bringing his own people into the system.
