CHICAGO -- Part of Pedro Grifol’s first staff as White Sox manager already was known, with pitching coach Ethan Katz and bullpen coach Curt Hasler returning, with Charlie Montoyo joining as bench coach.

On Tuesday, the White Sox announced the entirety of Grifol’s staff for the 2023 season: 

• Bench Coach: Montoyo
• Pitching Coach: Katz
• Bullpen Coach: Hasler
• Hitting Coach: José Castro
• Assistant Hitting Coach: Chris Johnson
• First-base Coach: Daryl Boston
• Third-base Coach: Eddie Rodríguez
• Major League Field Coordinator: Mike Tosar
• Senior Director of Sports Performance: Geoff Head

Montoyo, Castro, Rodríguez, Tosar and Head are new to the organization, and Johnson joins the staff from Triple-A Charlotte.

“I want to just say how thrilled we are with the staff that Pedro has put together and from a variety of experiences, from people from different organizations, different approaches,” White Sox general manager Rick Hahn said. “We are really excited about the level of talent he has surrounded himself with.

“I’d say we are looking forward to getting to work. But I know there already have been numerous meetings face to face with several players, as well as a handful of conversations with members of the front office as they prepare for Spring Training and what our game plan in other operations are going to look like.”

The coaching positions for Tosar and Head are newly created for the White Sox. Tosar also will be working with Castro and Johnson in the hitting realm.

“It's almost probably a two-and-a-half-headed monster when it comes to the hitting,” Grifol said. “Jose Castro, I have a long history with. I hired him as a hitting coordinator in Seattle. He's been in the game a long time; he's got a lot of experience. I believe he's one of the best in-game hitting coaches around. He's got tremendous instincts.

“Then Chris Johnson, who I just met a few weeks ago, I was really impressed by his knowledge of analytics, the terminology he uses. Those two, along with Tosar, who was part of that hitting program down in Kansas City, are going to make a great team when it comes to communication with the players, being able to make adjustments and adapt to every single player, every culture and also adapt to any type of analytics or sports sciences that's thrown our way as well. We're going to use it all.”

Rodríguez will lead the infield, with help from Tosar and Montoyo. Boston, who returns for his 11th season as first-base coach and 26th in the organization, will continue handling the outfield, while baserunning now will fall to Montoyo’s lead with a collective effort behind him. 

Montoyo, 57, enters his first season as the White Sox bench coach following a four-season stint (2019-22) as the manager of the Toronto Blue Jays. He recorded a 236-236 regular-season record and a Wild Card Series berth in 2020 at the helm of the Blue Jays before being dismissed following a 46-42 start to the 2022 season. During his tenure with Toronto, Montoyo managed All-Stars Bo Bichette, Vladimir Guerrero Jr., Teoscar Hernández, Alejandro Kirk, Alek Manoah, Marcus Semien, George Springer and Marcus Stroman.

“Obviously, Charlie's managed before, he's got a great track record,” Grifol said. “He's going to be right there next to me, from page one until the end. The way I was brought up, watching Ned Yost do it and then, obviously doing it with [Mike] Matheny, this is not a one-man show.

“This is all of us, together, preparing and then obviously during a game we'll be communicating, but somebody has to make that decision. That's going to be me, but he'll be right there with me.”
