The Mariners are hoping injured pitchers Hisashi Iwakuma and Taijuan Walker will return in late April, CBSSports.com baseball insider Jon Heyman reports.

The team is unofficially targeting the third week of April for the return of each, meaning the pitchers would miss just three or four starts. Iwakuma may have the splint removed from his injured finger by the end of this week. Walker is "said to be doing very well" as he recovers from a shoulder issue. The team will have to piece together the back end of the rotation until both pitchers are healthy enough to make their regular-season debuts.
