(CBS) The Cubs won’t retain pitching coach Chris Bosio, a source confirmed to 670 The Score’s Bruce Levine.

Bosio spent six years as the Cubs’ pitching coach, joining the organization with then-manager Dale Sveum ahead of the 2012 sason. He was then brought onto Joe Maddon’s coaching staff in 2015.

During a press conference Friday that followed the end of the season, Cubs president of baseball operations Theo Epstein indicated that decisions regarding the coaching staff would largely be left to Maddon, whom he said “would have every coach back that he wants back.”

Maddon and the Cubs could move to hire Jim Hickey, who left the Rays at the end of this season. Hickey was hired as Maddon’s pitching coach in Tampa Bay in 2006.

Bosio’s exit comes two days after the Cubs were eliminated by the Dodgers in five games in the National League Championship Series.

In 2017, the Cubs had a team 3.95 ERA, which ranked seventh in baseball. Their starters boasted a 4.05 ERA, which also ranked seventh.

The Cubs have yet to officially confirm the dismissal of Bosio, nor have they made any other staff changes.
