Marte (thumb) was placed on the 15-day DL on Sunday, Bob Dutton of the Tacoma News Tribune reports.
Marte suffered the thumb sprain Saturday, and although he was initially expected to miss a few games, a DL stint had not necessarily been in consideration. Now, the Mariners will make it official, calling up shortstop Chris Taylor to take his roster spot. While Taylor travels, the Mariners will award Shawn O'Malley the starting nod at shortstop Sunday.
