Liddi, Delabar, Saunders join Mariners

ANAHEIM -- Third baseman Alex Liddi and right-handed reliever Steve Delabar were promoted from Triple-A Tacoma along with outfielder Michael Saunders on Monday night and all three will join the Mariners on Tuesday in Anaheim.

Liddi and Delabar will be making their Major League debuts and will become the 17th and 18th rookies to play for the Mariners this season once they make their first appearances. Along with Saunders, their additions give Seattle 15 rookies of the 31 players on the roster.

Delabar, 28, will have to be added to the 40-man roster. A corresponding roster move will be announced Tuesday.

Liddi, 23, will become the first player born and raised in Italy to play in the Major Leagues. He led the Pacific Coast League with 121 runs scored this season and became just the second player in Tacoma history to combine 100 runs and 100 RBIs in the same season.

In 138 games with Tacoma he hit .259 with 32 doubles and 30 home runs.

Saunders, 24, will rejoin the Mariners for the second time this season and figures to provide needed backup in center field, where the club lost Franklin Gutierrez to a severe oblique strain in his side on Sunday.

Saunders hit .288 with 51 runs, seven home runs, 38 RBIs and an .864 on-base plus slugging percentage (OPS) in 61 games. He was on the Mariners Opening Day roster and appeared in 45 games, batting .168 while serving as the primary center fielder.

Delabar is the surprising addition among the trio. The 28-year-old reliever is a former Independent League pitcher who went 3-5 with a 2.25 ERA while splitting this season between Class A High Desert, Double-A Jackson and Triple-A Tacoma.

He was 1-1 with an 0.69 ERA with 18 strikeouts in 13 innings with Tacoma. Delabar was signed as a Minor League free agent on April 20 after not pitching in 2010. He pitched two seasons in independent leagues in 2008-09 after spending five seasons in the Padres organization.

Mariners manager Eric Wedge said those would likely be the last players promoted from Tacoma, whose season ended Monday, though reliever Dan Cortes was also with the Rainiers on an injury rehab stint and is expected to be brought off the 15-day disabled list later this week.

Gutierrez likely lost for season

ANAHEIM -- Outfielders Franklin Gutierrez and Casper Wells remained with the Mariners on Monday, but neither was available for duty as the series with the Angels opened. Gutierrez is likely done for the season.

Gutierrez strained his left oblique muscle reaching to swing at an outside pitch in the eighth inning of Sunday's 8-5 loss in Oakland, immediately clutching his side in pain and having to be helped off the field.

The 28-year-old Venezuelan missed 41 games at the start of the season while recovering from a stomach issue that hampered him the last half of 2010, but was finally showing a revival at the plate, hitting .286 over his last 27 games to raise his average to .224.

"He's obviously really sore today," manager Eric Wedge said. "He'll stay with us, let it calm down a little and then go back to Seattle."

Wells, who got hit by a Trevor Cahill pitch right above his left elbow on Sunday, is day to day on his return. But from the looks of things, it could take a few days for the swelling to go out of his triceps area.

"It's blown up on him a little bit," Wedge said. "I'm just happy it's not broken, the way he got hit."

Wells, acquired in the Doug Fister trade with the Tigers on July 30, said the arm stiffened up more overnight to where he's unable to swing a bat at this point and he's not sure on a timetable for his return.

"Just playing baseball for a few years, your pain threshold goes up," he said. "They were asking me on a scale of one to 10 how much does it hurt. I don't even know that scale. It just feels tight really. The triceps is kind of weak to do stuff right now."

It's been an adventurous couple of weeks for Wells, who was hit in the nose by a Brandon Morrow fastball on Aug. 17.

"This one caught me right above the elbow, but didn't hit flush on the bone," Wells said. "I was fortunate again. I'm just dodging bullets.

"I'm just icing this to get the swelling down so the muscles can work. I'll do anything possible to try to get out there. I don't like not playing."

Carp back in Mariners outfield

ANAHEIM -- Mariners manager Eric Wedge isn't happy about losing center fielder Franklin Gutierrez to a likely season-ending oblique strain, but the injury does open up more opportunities to see other outfield combinations as the final month plays out.

Mike Carp, who had been filling in for first base Justin Smoak for the past four weeks, moved back to left field on Monday. Rookie Trayvon Robinson got his second start in center field after playing mostly left field since his acquisition on July 31.

Carp said with a laugh that going back to left field is pretty much like riding a bike.

"I haven't been out there in a month, but I've been catching fly balls in batting practice," he said.

Wedge figures that may well be where the hot-hitting rookie's future lies with Seattle anyway since Smoak is the first baseman of the future. Smoak just came off the disabled list last week after his broken nose and cheek healed.

"He's already done a good job for us in left field," Wedge said of Carp. "He hasn't been out there in a while, but that's a place he's going to have to be able to play to get playing time. I look at Smoaker being able to play first base and DH and Carp being able to play first, DH and left field. So it works for us."

Robinson, who made an error in his one previous start in center for Seattle before being replaced in the late innings by Gutierrez, is more of a natural center fielder in Wedge's estimation.

"I'm looking forward to seeing him play out there a little bit and obviously we'll have others as well," Wedge said. "That part is good. I hate the fact Gut is hurt, but it gives us a chance to see some of these other guys in center field.

"I like the way [Trayvon] goes after the baseball. He's a center fielder by trade, but he's getting more comfortable in left field and I think he'll continue to do that."

Robinson doesn't have the strongest throwing arm, but Wedge said his other attributes can overcome that shortcoming.

"I think it's strong enough, if he can be accurate," Wedge said. "I think that's the key. A guy with his speed, you want to stop people with your feet anyway just by being aggressive to the baseball.

"I like his aggressiveness. I think he'll continue to improve his angles and overall awareness and the speed of the game up here. I think he's going to be fine out there."

Wedge said veteran infielder Chone Figgins will also be available for duty at all three outfield spots if needed and catcher Chris Gimenez has Major League experience in left and right if needed. Figgins, activated off the disabled list on Sunday, played 300 games in the outfield during his eight seasons with the Angels.
