Taijuan Walker struggled Tuesday night in his second rehab start for Triple-A Tacoma, telling Rainiers announcer Mike Curto afterwards that his arm felt good but he couldn't locate his fastball.

Walker allowed one run on one hit over two innings, but also walked four El Paso batters. How soon can we expect the imposing right-hander to make his 2014 debut with the big-league Mariners?
