Biscuits pitcher David Newmann has retired, while infielder Henry Wrigley and outfielder John Matulia have been activated from the disabled list.
Newmann, a left-yhander, was in his second season with Montgomery. He converted from a starter to the bullpen this year. In three appearances covering 4 2/3 innings, he had a 9.64 ERA with six walks.
Wrigley and Matulia stayed in extended spring training with back injuries. They were both with the Biscuits last year.
