The Toronto Blue Jays reassigned bullpen coach Pat Hentgen on Saturday and replaced him with Bob Stanley, who spent the last two seasons as a pitching coach with the team's triple-A affiliate in Buffalo.
The move will give Hentgen the "time needed to support his family and his father's current health issues," the Blue Jays said in a release.
Hentgen spent 10 of his 14 big-league seasons with the Blue Jays, winning a Cy Young Award in 1996. He retired after the 2004 season.
Hentgen, 45, returned to the team in 2007 as a club ambassador and also spent the 2011 season as bullpen coach. It wasn't immediately clear what his new duties will be.
Stanley, 59, played 13 seasons with the Boston Red Sox and was named to the Red Sox Hall of Fame in 2000.
Toronto finished last in the American League East last season with a 74-88 record.
Manager John Gibbons will return for the 2014 campaign. His staff includes Stanley, bench coach DeMarlo Hale, hitting coach Kevin Seitzer, pitching coach Pete Walker, third base coach Luis Rivera and first base coach Tim Leiper.
The Blue Jays will open the regular season on March 31 at Tampa Bay.
