Brian McTaggart says that the Astros have hired Tony DeFrancesco as their Triple-A manager in Oklahoma City.
The B-R Bullpen has some background for you. The short version is that he had managed in Oakland's organization since 1994, and with Oakland's Triple-A franchise in Sacramento since 2003, and won three league championships in five years. His overall record of 580-427 (.576) in the PCL is pretty impressive, too.
In 2008, he was Oakland's Third Base Coach.
Within this McTaggart blog post we read that Burt Hooten and Keith Bodie will keep their jobs as pitching coach and hitting coach, respectively.
Director of Player Development/Ex-Ricky Bennett Fred Nelson:
"Tony is a proven winner and developer of talent at the Triple A level. He brings a lot of personal pride and respect for the game and has an aggressive managing style with a reputation for developing disciplined players with winning mentalities. He is a very hard worker with high expectations for himself and for the players he manages. We're excited to have Tony on board."
