Davis, 58, was a three-time All-Star and three-time World Series champion during his playing career for the San Francisco Giants (1981-87), California Angels (1998-90, 1993-96), Minnesota Twins (1991-92), Kansas City Royals (1997) and New York Yankees (1998-99).
He hit .274 in his career with 350 home runs and 1,372 RBI.
After his career, he served as the hitting coach for the Oakland Athletics and Boston Red Sox before joining the Cubs.
In his lone season in Chicago, the Cubs hit just .249 as a team after the All-Star break and just .239 in September. They saw a major dip in power, going from 223 homers last season (ninth in baseball) to just 167 this year (22nd), while also going from 822 runs in 2017 (fourth) to 761 this year (ninth).
Inconsistency plagued the offense as well. As James Neveau of NBC Sports Chicago noted, the Cubs scored one run or none in 40 games this season. That inconsistency reared its ugly head when their season was on the line, as they only scored one run in their divisional tiebreaker against the Milwaukee Brewers and one run in a Wild Card Game loss to the Colorado Rockies.
On an individual level, Javier Baez had a breakthrough year and put himself in the MVP conversation, hitting .290 with 34 homers and 111 RBI in 160 games. But Kris Bryant took a step back, hitting .272 with 13 homers and 52 RBI in 102 contests.
