Polanco (back) isn't starting Wednesday's game against the Mariners.
Polanco continues to deal with back soreness and will be held out of the lineup for a third consecutive game. Manager Rocco Baldelli said Wednesday that Polanco underwent an MRI that didn't reveal anything too concerning, so he should be considered day-to-day for now, Betsy Helfand of the St. Paul Pioneer Press reports. Luis Arraez will shift to the keystone while Jose Miranda draws the start at first base Wednesday.
