Twins manager Paul Molitor suggested after Sunday's game that Plouffe has been playing at less than 100 percent recently, ESPN reports.
In all likelihood Plouffe is still bothered a bit by the intercostal strain that landed him on the DL for the last couple of weeks in April, but Molitor didn't go into specifics on what exactly is ailing the third baseman. Minnesota doesn't get another break in their schedule until May 26, so after sitting out Sunday's game, don't be surprised if Plouffe receives a couple more days off in the meantime.
