ANAHEIM -- Mariners first baseman Mike Carp was named the American League Rookie of the Month for August after an excellent month that pushed him to the forefront of the club's future plans.

Carp, who bounced between Triple-A Tacoma and the Mariners for the previous two seasons, grabbed hold of his first full-time opportunity with Seattle by hitting .313 with 25 RBIs, eight doubles and six home runs in 27 games in August.

"It's a great accomplishment," Carp said. "Just to play a month was great, and to have the success I had was a lot of fun. We've got one more month now and I'd like to have another good one."

The 25-year-old posted a .545 slugging percentage and a .353 on-base percentage in August and tied a Mariners rookie record with 25 RBIs in a single month, set by Danny Tartabull in July 1986.

Carp filled in for injured first baseman Justin Smoak for most of August at first base. He's now playing left field and designated hitter, two spots that likely will be his future with the Mariners, according to manager Eric Wedge.

Carp had a 20-game hitting streak snapped on Aug. 21 after batting .363 during that surge.

"It's been a crazy year, up and down, up and down," Carp said. "To finally have a good 'up' means a lot. We went through some struggles as a team, but the rookies have had a lot of success and it means a lot just to be able to play that much."

Carp is the fourth Mariners player to receive AL Rookie of the Month honors and the first position player since Ichiro Suzuki did it four times in 2001. Pitcher Michael Pineda earned the honor this April.

Liddi becomes first Italian-raised big leaguer

ANAHEIM -- Third baseman Alex Liddi was at Angel Stadium a year ago to play in the Futures Game, but the future finally arrived in force Tuesday as the Italian native was promoted to the Mariners from Triple-A Tacoma.

Liddi, 23, will become the first graduate of the Major League Baseball European Academy to play in the Majors, as well as the first Italian-born-and-raised player to make it, as soon as he gets in a game for Seattle.

Six Italian-born athletes have previously played in the Majors -- the last being Reno Bertoia in 1962 -- but all of those players moved to the United States as youngsters.

"It's an honor and something special to think I represent all my friends and all the people in Italy that didn't have this chance that I've had," Liddi said before Tuesday's game against the Angels. "For me and my family and all the people in Italy who love this game, it's something special."

Liddi just finished an outstanding season at Triple-A, leading the Pacific Coast League with 121 runs scored, ranking third in home runs (30) and fourth in RBIs (104). He was just the second Tacoma player ever to total 100 runs and 100 RBIs in the same season.

Liddi was born and raised in Sanremo, Italy, and came to the United States in 2006 to play for the Peoria Mariners after signing with Seattle as an international free agent.

"My dad played baseball and my mom played softball. Not a lot of people do that in Italy," Liddi said. "It was always my passion. I grew up on a baseball field and it was always part of my life.

"Baseball is getting better there. They have a semi-pro league with a lot of ex-big leaguers. Of course, it's not close to here, but hopefully it'll keep getting better and we'll have more players in Italy doing what I'm doing."

Manager Eric Wedge said he wants to continue seeing rookie Kyle Seager at third base, but that Liddi will "get some playing time" when possible.

"I wouldn't say a lot, but he'll get some time," Wedge said. "Let him get up here today and work out, be a part of it. I'll try to get him in there as much as I can, but I want to continue playing Seager, too."

Gutierrez put on 60-day DL; year officially over

ANAHEIM -- Mariners center fielder Franklin Gutierrez's season officially came to an end Tuesday, as the club placed him on the 60-day disabled list to create room on the 40-man roster for the addition of pitcher Steve Delabar.

Gutierrez suffered a strained oblique muscle in his left side while swinging at a pitch Sunday in Oakland. The Gold Glove outfielder began the season on the disabled list with a stomach issue, missing the first 41 games of the year.

He wound up hitting .224 with one home run and 19 RBIs in 92 games while lengthening his consecutive fielding chances without an error to 786, an American League record in center field.

Despite Gutierrez's shortened season, manager Eric Wedge said he doesn't think it would be a good idea for Gutierrez to play Winter Ball once his oblique heals.

"For me, I probably would not advise it," Wedge said. "He needs to get healthy and get strong and have a good offseason, feel good physically and get to a good place mentally. I think it's hard to do all that and play Winter Ball, too."

Gutierrez batted .282 over his last 33 games, but he never fully regained the power that saw him hit 18 home runs in 2009 before stomach problems began affecting him in the second half of last season.

"The time he lost when he was sick and going through everything early in the year, it probably defeated everything," Wedge said. "But he worked hard and did some specific things to get himself where he needed to be with his lower half and mindset and approach, and it paid off for him.

"And I think if he'd kept hitting, eventually a little more power would have come, too. You have to hit first, and he'd done that for a month or so."

Worth noting

• Outfielder Casper Wells continues to be bothered by a sore elbow after being hit by a pitch Sunday. Wedge said he'd have to see how Wells performed in batting practice Tuesday before determining his availability.

Michael Saunders started in center field on Tuesday with Trayvon Robinson moving back to left, but Wedge said Wells would continue getting much of the playing time when he gets healthy, while Saunders will fill in where possible at all three outfield spots.

• The Mariners' game against the Rangers on Sept. 17 at Safeco Field will be played at 4:10 p.m. PT, the club announced. The starting time had been listed as TBA.

• The Mariners' five errors in Monday's 7-3 loss to the Angels were their most miscues in a game since the club committed five on July 13, 1995, against Toronto. The club record for errors in a game is nine, set on June 25, 1978, vs. the Brewers.

• The addition of Delabar and Liddi on Tuesday raised the Mariners' rookie total to 14 on their 31-man Major League roster. The team has played 16 rookies this season, the most in the Majors, with 10 of those players making their debuts in 2011.
