Giants manager Gabe Kapler is on the verge of losing a piece of his 13-person staff, with reports saying assistant pitching coach Ethan Katz will move to the White Sox as pitching coach under new manager Tony La Russa. Barstool Sports first reported the hire Thursday. Katz, 37, had been the Giants' assistant minor-league pitching coordinator in 2019 before Kapler elevated him to the big-league staff to work under pitching coach Andrew Bailey.
