Buxton was optioned to Triple-A Rochester on Sunday, Phil Miller of the Minneapolis Star Tribune reports.
Buxton has struggled mightily in the second half, going just 6-for-46 at the plate. The move opens up a roster spot for Trevor Plouffe's (ribs) activation from the disabled list Monday. It's likely not the last we'll see of Buxton, who will head back to the minors and try to get things sorted out at the dish.
