Hitting coach Marcus Thames, pitching coach Ethan Katz, assistant pitching coach Matt Wise, first base coach Jason Bourgeois, third base coach Justin Jirschele, and catching coach Drew Butera are all expected to return.  Grady Sizemore will also return to the coaching staff after serving as Chicago’s interim manager when Pedro Grifol was fired in early August.  Interim bench coach Doug Sisson and interim assistant hitting coach Mike Gellinger won’t be returning to those roles, but are expected to take other jobs in the organization.

While the White Sox didn’t feel the need to entirely revamp the coaching staff in the wake of a 121-loss season, it should be noted that many of these coaches were already relative newcomers to the organization.  Thames, Wise, Bourgeois, and Butera were all hired just last offseason, and Jirschele was installed last August when former third base coach Eddie Rodriguez was also fired along with Grifol and former bench coach Charlie Montoyo.

There’s really nowhere to go but up for the White Sox in the wake of the worst season in modern baseball history, though Venable and his staff will have another long year ahead of them as the Sox continue their rebuild.  Obviously wins aren’t expected for now, as Venable and the coaches face the broader challenge of helping develop the team’s younger players and changing what reportedly became a toxic clubhouse culture.

“The Sox are expected to announce more staff changes this week,” Van Schouwen writes, though pitching coach Ethan Katz is expected to remain with the club.  Katz has spent the last three seasons in Chicago, after previously working as assistant pitching coach with the Giants and in various minor league coaching/coordinator roles with the Giants, Mariners, and Angels.

Castro and Johnson are moving on after just one season in their current roles, as clearly the White Sox felt an immediate shakeup was needed in the hitting coach ranks.  The numbers bear a strong argument for a quick change — the Sox ranked 29th of 30 teams in wRC+ (83) and runs scored (641) last season, while hitting a collective .238/.291/.384.  Those slash line numbers respectively rank 25th in the league in batting average, 30th in OBP, 26th in slugging percentage.

While the coaching staff doesn’t bear sole responsibility for these struggles, “Sox hitters were said to be torn between multiple hitting voices on the staff,” Van Schouwen wrotes.  Major League field coordinator Mike Tosar also worked with batters in addition to Castro and Johnson, and while Tosar’s status for the 2024 staff isn’t yet known, it could be that the White Sox might look to simplify things by having a sole hitting coach and Tosar contributing.

The 65-year-old Castro is a longtime baseball man, with 14 years as a player in the minors and over three decades of experience at the Major League and minor league levels as a coach — usually as a hitting coach, though also with some brief stints as a Triple-A interim manager for the Mariners and as a quality assurance coach with the Cubs.  Before joining the White Sox last winter, Castro was an assistant hitting coach with the Braves for the previous eight seasons.

Johnson is best known for his eight-year MLB playing career from 2009-16, spent mostly with the Astros and Braves.  The 39-year-old worked as the hitting coach for the White Sox Triple-A affiliate in 2021-22 before receiving his promotion to the big league staff.

Boston has been the longest-serving member of the coaching staff (11 seasons) and one of the longer-tenured members of the White Sox organization in general, working on the South Side for the last 26 seasons.  Boston, 60, played seven seasons with the White Sox (1984-90) during his 11-year MLB career, and he worked as a roving outfield instructor in the team’s farm system before becoming first base coach.

NOVEMBER 1: The White Sox landed on their new skipper this morning, with various reports indicating that Royals bench coach Pedro Grifol will take over the dugout. Grifol has apparently already tabbed his top lieutenant. Former Blue Jays manager Charlie Montoyo will join Chicago’s staff as bench coach, as first reported on Twitter by Northbrook Bob.

It could be the start of a significant coaching staff overhaul on the South Side, as Ken Rosenthal of the Athletic tweeted this morning that a number of the members from Tony La Russa’s staff will not return. Pitching coach Ethan Katz is a seeming exception, as Rosenthal notes he’s expected back for a third season. Daryl Van Schouwen of the Chicago Sun-Times hears the same and reports that bullpen coach Curt Hasler is likely to stick around as well. The rest of the staff makeup seems to be up in the air.

Most notably, that includes now-former bench coach Miguel Cairo. The longtime big league infielder was hired as La Russa’s right-hand man going into the 2021 season. He spent two years as Chicago’s bench coach and took over as acting manager at the end of this past season when La Russa stepped away to attend to the health problems that eventually led him to vacate the managerial position. Cairo got an interview from the Sox for the full-time managerial position, but he obviously didn’t land that job. Now, it’s an open question whether he’ll return to the organization in any capacity.

Montoyo adds an experienced voice to the Chicago coaching staff. The 57-year-old has coached or managed in the majors for the past seven years. After more than a decade and a half managing in the Rays farm system, Montoyo got a bump to the MLB staff as Kevin Cash’s bench coach heading into the 2016 campaign. He held the role for three seasons before the Blue Jays hired him as their skipper over the 2018-19 offseason.

The Puerto Rico native managed the Jays for three-plus seasons, leading Toronto to a playoff berth in 2020. The Jays narrowly missed the postseason last year. Toronto started the 2022 campaign 46-42 and held a playoff spot as the All-Star Break approached, but the Jays decided to go in another direction and fired Montoyo on July 13. Bench coach John Schneider was promoted and guided the team to a 46-28 record down the stretch, clinching a Wild Card berth before losing in the first round of the playoffs to the Mariners.

Montoyo’s past bench coach and managerial experience should be welcome for Grifol, who’ll manage an MLB team for the first time. He and the front office figure to build out the remainder of his staff over the coming weeks. Hitting coach Frank Menechino, assistant hitting coach Howie Clark and base coaches Daryl Boston and Joe McEwing are among those who appear to have uncertain futures as the Sox shuffle their staff.

• Before signing perennial Gold Glove shortstop Andrelton Simmons, the Twins consulted with Jorge Polanco and Luis Arraez about the move, tweets the Athletic’s Aaron Gleeman. Since both Polanco and Arraez stand to be displaced from their expected roles, the Twins were wise to secure their buy-in. Still, it’s a courtesy they didn’t have to observe. Polanco has been the team’s regular shortstop for most of the past four seasons. As for Arraez, projection systems from THE BAT X to Steamer to ZiPS forecast Arraez to lead the Majors in batting average, as pointed out on the Athletic’s Rates and Barrels podcast. While it’s not the 1990’s anymore, it’s still surprising to push a potential batting champ out of a regular role. That said, we tend to overrate the starting lineup on opening day, and underrate the impact and opportunity that exists for players in “bench” roles.
• Now that J.T. Realmuto, James McCann, and (unofficially) Yadier Molina are all off the market, Salvador Pérez can begin to imagine his own free agency a year from now. The Kansas City staple hasn’t spoken with the Royals about an extension, though he’s on the record saying he’d like to retire a Royal, per Lynn Worthy of the Kansas City Star. Pérez fell off the map while missing the 2019 season, but he bounced back in a big way during the shortened 2020 season by slashing .333/.353/.633 over 156 plate appearances. It’s easy to imagine the Royals quietly extending their MVP from the 2015 World Series, but if he has anywhere near as productive a season this year as last, there may be legitimate competition for his services. Lest we forget exactly how highly-regarded Pérez was as the game manager of the Royals’ competitive run from 2013 to 2017, he made six All-Star games, won three Silver Sluggers and five Gold Glove Awards.  He’ll have wrapped his age-31 season when he hits free agency after 2021.

“Tony deserves all the assumptions and protections granted to everyone in a court of law, especially while this is a pending matter,” the White Sox stated. “Once his case reaches resolution in the courts, we will have more to say. The White Sox understand the seriousness of these charges.”

La Russa was arrested in February in Arizona after registering a blood alcohol level of .095, which is above the legal limit of .08. Charges weren’t filed until Oct. 28. The White Sox were aware of the matter, but that didn’t stop them from bringing back La Russa, who’s friends with owner Jerry Reinsdorf and who previously managed the team from 1979-86.

If La Russa does keep his job, Ethan Katz will be his pitching coach, as Dave Williams of Barstool Sports first reported. The 37-year-old Katz, who will take over for longtime White Sox pitching coach Don Cooper, already has a connection with the team in ace Lucas Giolito. Katz was Giolito’s pitching coach at Harvard-Westlake High School in Los Angeles and has spent recent offseasons continuing to work with Giolito. He has also had runs with multiple major league organizations (Angels, Mariners and Giants) and was most recently San Francisco’s assistant pitching coach.
