The Chicago Cubs made several changes to their major-league coaching staff Thursday, including the addition or subtraction of four ex-Midwest Leaguers.

The Cubs dismissed pitching coach Chris Bosio, hitting coach John Mallee, and third-base coach Gary Jones. Bosio and Jones played in the Midwest League, and Jones also is a former MWL manager. (Bosio reportedly is close to joining the Detroit Tigers as new manager Ron Gardenhire‘s pitching coach.)

Meanwhile, the Cubs added Jim Hickey as pitching coach, Chili Davis as hitting coach, and Brian Butterfield as third-base coach. Hickey was manager Joe Maddon’s pitching coach with the Tampa Bay Rays. Davis and Butterfield most recently were on the Red Sox coaching staff of John Farrell, who was fired by Boston earlier this month.

Hickey and Davis played in the Midwest League. As a White Sox farmhand, Hickey pitched for the 1984 Appleton Foxes, going 13-5 with a 1.81 ERA, 20 saves, 96 strikeouts and 32 walks in 99.1 innings (49 games). Davis was a catcher and outfielder for the 1978 Cedar Rapids Giants before advancing to a 19-year career in the major leagues. He batted .281 with 16 HR, 73 RBI and 15 SB in 124 MWL games.

Bosio’s Midwest League career consisted of 44 starts for the Beloit Brewers (17 in 1983, 26 in 1984, and one in 1990). His overall MWL record was 20-16 with a 3.80 ERA, 14 complete games, 229 strikeouts and 98 walks in 291.2 innings. He spent 11 seasons in the major leagues, pitching for the Milwaukee Brewers and the Seattle Mariners.

Jones played eight seasons in the minor leagues, including one in the Midwest League. A second baseman, he batted .308 with 6 HR, 34 RBI and 58 SB in 133 games with the 1983 Quad City Cubs. His double-play partner was future major-leaguer Shawon Dunston, who batted .310 with 4 HR, 62 RBI and 58 SB in 117 games with QC.

Jones returned to the Midwest League as a manager three times, for the Madison Muskies in 1991 and 1993, and the Fort Wayne Wizards in 2003. He was named the MWL Manager of the Year in 1991, when he led the Muskies to the championship series. (They were swept in three games by the Clinton Giants.) His Wizards team also made the playoffs, but were knocked out in the first round by the Battle Creek Yankees.
