Gutierrez is on the 15-day disabled list with a partially torn pectoral muscle in his chest and has been working at extended Spring Training with low Minor League players at the team's complex in Peoria. But while his pectoral muscle is nearing full recovery after two months, the heel has become a problem in the past week.
"We're going to give him a couple more days off that heel," manager Eric Wedge said on Sunday. "Right now, we're targeting Tuesday for him to [resume running]. He's still taking batting practice and throwing. That's all good. The heel is the issue now."
Once he's at full strength, Gutierrez will be sent out on a Minor League rehab assignment and likely be given the full 20 days to regain his timing, since he hasn't played much since the start of Spring Training.
Left fielder Mike Carp is closer to returning to the Major League club. Carp, on the 15-day disabled list with a sprained right shoulder suffered on Opening Day in Tokyo, went 1-for-4 with a two-run double for Triple-A Tacoma on Saturday and was scheduled to play designated hitter again on Sunday.
He's hitting just .149 in 47 at-bats, but has hits in his last three games now. Carp's 20-day rehab stint runs out on Wednesday, so the Mariners will need to make some decisions by then.
"We'll revisit that in a couple days, too," Wedge said. "He's playing full games and feels pretty good."
