Culpepper has been extremely good for a 23-year-old at Triple-A and the Twins' shortstop situation has been a season-long weakness.
Lewis played first base and second base in his first two games back in the Twins' lineup, and their crowded infield may soon be adding a top-100 prospect.
Lee moving off shortstop has domino effects on the Twins' infield involving Royce Lewis, Kaelen Culpepper, and Luke Keaschall.
Jeffers was off to a great start offensively and defensively, and the impending free agent will be nearly impossible for the Twins to replace.
Less than a week after demoting the .167-hitting Matt Wallner to Triple-A St. Paul, the Twins made the same decision with the .163-hitting Lewis.
Wallner losing starts to Austin Martin versus right-handers was a sign the Twins were running out of patience with the struggling slugger.
It wasn't a pretty first 41 games for the Twins, but they've had plenty of standout individual performances worth appreciating.
