The Twins activated Trevor Plouffe from the 15-day disabled list today, 24 days after Plouffe was described as "day-to-day" with a bruised right thumb. (To be fair, this represents one of the Twins' medical staff's greatest successes of the past decade, so bravo to them.)
To make room on the roster, the star-crossed Tsuyoshi Nishioka was returned to Rochester, where hopefully the pop-ups are not so high and the ground balls aren't so sharp.
Plouffe has batted .259 with 19 home runs in 2012, a breakout season for him at the plate. Since June 1, Plouffe has been verging on "slugger" territory, bashing 14 homers in 42 games and putting up a .317/.373/.634 batting line. Continuing those numbers would cement him at third base in the Twins' plans.
On the flip side, Nishioka was 0-12 with a walk in his stint, and made three errors, and is in the running with Clete Thomas for "worst major-league stint by a Twin in 2012." In general he appears to be a member of the public who won a contest to play in the major leagues, so he's still got some things to work on at Rochester.
