NEW YORK – The Toronto Blue Jays have fired Gary Allenson, their manager at double-A New Hampshire, and Willie Collazo, the pitching coach at low-A Lansing, industry sources told Sportsnet.

Their dismissals follow that of Rich Miller, who managed short-season A Vancouver to a Northwest League title, as the Blue Jays continue reshaping their player-development staff.

Allenson spent three seasons managing at triple-A Buffalo before the Blue Jays moved him down to New Hampshire this season, where prospects under his watch included Richard Urena, Anthony Alford, Lourdes Gurriel Jr., Ryan Borucki, Sean Reid-Foley and Conner Greene.

Bobby Meacham, who had been in New Hampshire, took over as Bisons manager this year and will return to Buffalo next year.

Collazo, who pitched in the Blue Jays system from 2010-12, was the pitching coach at Vancouver last year before getting promoted to Lansing this past season. The pitching staff there included well regarded right-hander Justin Maese.
