Whalen (calf) was seen walking around without crutches Tuesday, Bob Dutton of The Tacoma News Tribune reports.
This is certainly a good sign moving forward, although it's unclear how much activity he's actually been able to do while off of the crutches. Unless Whalen has made significant progress in his rehab from the calf strain, he very well could open the season on the disabled list, but things should become clearer in the coming days as he ramps up his activity further.
