HOUSTON -- The Astros on Thursday announced that their entire coaching staff would return for the 2023 season, with one additional member. Tommy Kawamura will join the field staff as Major League game planning coach, transitioning from the baseball operations staff.

Kawamura has served as the Astros' manager of advanced scouting for the past few seasons and will join manager Dusty Baker’s staff as Houston tries to defend its World Series title. The returning coaches are bench coach Joe Espada, third-base coach Gary Pettis, first-base coach Omar Lopez, hitting coaches Alex Cintrón and Troy Snitker, pitching coaches Josh Miller and Bill Murphy, quality assurance coach Dan Firova, Major League coach Michael Collins and Jason Kanzler, who is now the assistant hitting coach.

“Well, consistency is the key,” Baker said. “I mean, they know what I require. I know what their strengths and what their weaknesses are. You try to put people in areas where they will most likely succeed. And that makes it easier on the players also to know who they can go to with this problem or who they can go to with this other problem or where to go get whatever information that they have.”

Pettis is the longest-tenured member of the coaching staff, having joined the club prior to the 2015 season. He’s been a part of each one of the Astros’ seven playoff appearances in the last eight seasons, including World Series titles in '17 and ’22. He missed time in each of the last three seasons with health issues.

Cintrón will return for his seventh season, Espada for his sixth season, Miller and Snitker for their fifth seasons, Lopez and Collins for their fourth seasons and Firova and Murphy for their third seasons. Kanzler joined the staff prior to last season with the title of Major League coach.

Baker, 73, became the oldest manager to win a World Series when the Astros took down the Phillies in six games in the Fall Classic. That capped an incredible year for Baker, who picked up his 2,000th career win early in the season. The Astros gave Baker a one-year contract extension for 2023 days after they won the World Series.

“Our staff is like going to the library, you know?” Baker said. “I used to go to the library and you just gotta know where you look when you go to the library, because it's all there. And my staff is like going to the library.”
