One of the most clicked-on posts in this blog's history was this 2012 entry listing former Twins (and some former stars of note) working in farm systems around baseball.
Baseball America recently published another page of minor league managers and coaches, and I went over it with a highlighter marking former Twins.
There's been quite a bit of turnover in two years, as one might expect. At least two of those in the 2012 post moved all the way up to the majors — Mike Redmond is, of course, the manager of the Miami Marlins, and Matthew LeCroy is now the bullpen coach in Washington. Some have shifted organizations and levels. Others are out of baseball completely.
Here's the current list:
Former Twins managing Twins farm teams: Doug Mientkiewicz, High A (Fort Myers); Ray Smith, Rookie (Elizabethton).
Former Twins coaching for Twins farm teams: Chad Allen, Double A (New Britain); Jim Dwyer, High A (Fort Myers); Tommy Watkins, Low A (Cedar Rapids)
Former Twins managing in other systems: Phil Nevin (Triple A, Arizona); Matt Merullo (Short-season A, Baltimore); Brian Buchanan (Low A, Kansas City); Denny Hocking (High A, Angels); Wally Backman (Triple A, Mets); Tom Prince (High A, Pittsburgh)
Former Twins coaching positions in other systems: John Moses (High A, Atlanta); Brian Harper (Triple A, Cubs); Gary Ward (High A, White Sox); Andre David (Double A, Kansas City); Nelson Liriano (Rookie, Kansas City); Butch Wynegar (Triple A, Yankees); Mike Pagliarulo (Triple A, Pittsburgh); Orlando Merced (Short-season A, Pittsburgh); Jacque Jones (Triple A, San Diego)
Former Twins coaching pitchers in other systems: Paul Abbott (Low A, Boston); Steve Luebber (High A, Kansas City); Scott Aldred (Triple A, Yankees); Aaron Fultz (Short-season A, Philadelphia)
Former Twin listed but not actually working: Frank Viola was supposed to be the pitching coach for the Mets' Triple A affiliate in Las Vegas, working with former teammate Wally Backman, but he had open heart surgery earlier this month and won't be working this season.
Former Twins pitching coach working in the minors: Dick Such, who was Tom Kelly's pitching coach for TK's entire managerial career, is the pitching coach for the Red Sox's Gulf Coast League affiliate (Rookie level) in Fort Myers.
