SEATTLE -- Injured outfielder Franklin Gutierrez is still dealing with the effects of a concussion he suffered almost a month ago, and the Mariners are uncertain when the former Gold Glover will return.
"We're not exactly sure what Gutierrez's time is right now. He's still being evaluated," manager Eric Wedge said prior to Tuesday's game. "He had tests yesterday and had more tests today. ... They're just checking him some more, making sure that nothing else is going on. We should know more probably after Wednesday."
Gutierrez was placed on the disabled list after suffering a concussion when he was hit in the head by a pickoff attempt on June 28. He was working back slowly, but his physical activity was shut down on Saturday.
This is the second stint on the disabled list this year for Gutierrez, who started the season with a torn pectoral and plantar fasciitis and didn't play a game with the Mariners until June 14. This is the second consecutive season Gutierrez has missed significant time.
Mariners call up Robinson along with Carp
SEATTLE -- In a rare time with two open big league spots, the Mariners had two moves to make on Tuesday to fill out their 25-man roster. One move came as anticipated, and the other was more of a surprise.
As expected, the Mariners recalled Mike Carp from his rehab assignment in Triple-A Tacoma and activated him from the 15-day disabled list. They also recalled outfielder Trayvon Robinson from Tacoma in a more surprising move.
The Mariners had two open spots at the big league level after trading Ichiro Suzuki for a pair of prospects and the announcement that first baseman Justin Smoak was being sent to Tacoma following Monday's game.
"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."
Carp to stick to first base, DH duties
SEATTLE -- With the departure of Justin Smoak to Triple-A Tacoma following Monday's game against the Yankees, recently recalled Mike Carp will assume the role of the everyday first baseman, said Mariners manager Eric Wedge.
Carp mostly played left field before two stints on the disabled list, but worked solely at first base while rehabbing his most recent shoulder injury while in Tacoma. On days that Carp is the designated hitter or out of the starting lineup, Wedge said he will also use second baseman Dustin Ackley at first.
Meanwhile, catchers John Jaso and Jesus Montero continue to take ground balls at first during practice. Jaso has played one career game at first, while Montero has only played behind the plate. Wedge said he is uncertain if he'll put Montero in at first during a game situation this season, but likes him taking grounders at both first and third during batting practice.
"I like ... the actions and the athleticism, I think it's a good thing," Wedge said. "Whether you take balls at short or second or whatever, you get on the left side of the infield or up the middle, even if you're messing around, I think it's good for your athleticism, I think it's good for your hands."
Entering Tuesday's game against the Yankees, Mariners starters were 3-1 with a 1.80 ERA and 25 strikeouts over their last five starts.
John Jaso extended his home hitting streak to 10 games on Monday. During the streak he is hitting .464 (13-for-28) with two home runs, eight RBIs and four runs scored.
