With rain in the forecast for Tacoma, the Mariners opted to send Gutierrez to a spot where the weather is expected to be much nicer.
Gutierrez has been recovering from stomach problems and the Mariners want to see him play some games in the Minors before he returns to Seattle's lineup.
"For me, it's the energy level and the strength," Mariners manager Eric Wedge said. "He doesn't have to be back to where he was weight-wise. And then the baseball reps. ... timing, seeing the ball off the bat. We need to make sure he can get through a full game and can play at least every other day at first. Those are some of the parameters that I have in mind."
