"Mike's been playing first base down there, he's going to play some first base up here, along with mix him in at DH too," manager Eric Wedge said. "Trayvon will be more of an extra outfielder for us, he can play all three."
Carp is coming off his second stint on the DL for his right shoulder, which he initially hurt during the season opener in Japan diving for a ball in left field. Carp is hitting .157 with four home runs and 12 RBIs in 32 games with the Mariners this season, but he never fully recovered from the separated shoulder he suffered in Japan.
Wedge has said he will use Carp as a first baseman and designated hitter upon his return, limiting the stress on his shoulder by keeping him out of left field.
"I was basically trying to get the shoulders healthy and strong again because it was really affecting my swing," Carp said of his rehab assignment. "Trying to break my bad habits I created when I tried to come back a little too early.
"Still have in my mind [a] little, I wouldn't say anxiety, but trying to get over that still. But I've been in there every day, been playing, been getting a lot of at-bats, playing a lot of first base, haven't had any setbacks this time. Things are good, so I can only expect to go forward from here and get stronger and hopefully get back to exactly where I was last year, maybe better."
This is Robinson's second stint, and first of the season, with the Mariners since the team acquired him via trade last season. The 24-year-old was hitting .265 with nine home runs, 41 RBIs and 50 runs scored in 83 games for the Rainiers this season. Robinson has made starts in each outfield position this year.
"I thought I played pretty good baseball," said Robinson of his time in Tacoma. "I'm just looking at the average, the average wasn't there. It is what it is. As far as playing the game, I felt like I did a better job helping the team win, getting in scoring position, stealing bases, giving the opportunity for somebody to drive me in."
"He's working on different areas of his game he needs to work on, whether it be offensively, defensively, on the basepaths," Wedge said. "[He's] done a nice job on the basepaths, [is] getting better in the outfield. [I'm] looking forward to seeing him at some point in time."
