La Russa left the team on Aug. 30 with an "undisclosed medical condition" that was later found out to be a heart issue. After undergoing an evaluation in Chicago, La Russa flew to Arizona to visit his doctors and have a pacemaker inserted.
It was reported La Russa was "getting better" and he planned to return to the dugout "early next week," signifying a possibility to return for their weekday series against the Colorado Rockies. However, now his return doesn't seem imminent, based on La Russa's interview.
Bench coach Miguel Cairo stepped up as acting manager to lead the clubhouse during La Russa's departure. Since then, the Sox are 9-3, snatching four series wins under Cairo's lead.
