"The Astros made considerable changes to their staff including in the dugout, where former Cardinals bench coach Joe Pettini is replacing Al Pedrique as bench coach after Pedrique declined a reassignment to bullpen coach.

General manager Jeff Luhnow also announced the hiring to his staff of Dan Radison as special assistant to the GM in player development, Mike Elias as special assistant to the GM in scouting and Matt Sinatro as catching and advance scouting coordinator.

Pettini worked for 10 years under Tony La Russa, winning three National League pennants and two World Series titles with the Cardinals (losing the third to the Red Sox, who featured current Astros manager Brad Mills as bench coach)."
