Triunfel, a 22-year-old middle infielder, and Jimenez, a 30-year-old first baseman and designated hitter, will be making their first stints in the Major Leagues.
Jimenez, who hit .310 with 20 home runs and 81 RBIs for Tacoma, had to be added to the 40-man roster. To make room, the Mariners designated Johermyn Chavez for assignment, which means they now have 10 days to trade, release or outright the young outfielder.
The 6-foot-3, 280-pound Jimenez has been with seven Minor League organizations since 1999 -- the A's, Orioles, Dodgers, Twins, Red Sox, Nationals and Mariners -- and also spent 2009 playing in Japan. He emerged this year as the Rainiers' Offensive Player of the Year and was a Pacific Coast League All-Star.
"I've been waiting for 13 years," said Jimenez. "Getting a chance now to play with these guys is very cool. I'm so proud of myself because I never gave up."
Jimenez's mother has been visiting him in Tacoma for the past month and immediately got on the phone to his father back in Barquisimeto, Venezuela, where Jimenez's wife and two children also live.
"She started crying," Jimenez said, "and she told my dad, "Antonio, Luis got called up!" And all I could hear was 'Take it easy, breathe, breathe, drink some water.' They were pretty excited."
Triunfel is eight years younger than Jimenez, but has been in the Mariners organization much longer. He made his pro debut at 17 in the Class A Midwest League and has been a well-regarded prospect ever since, though his climb was slowed by a broken leg that wiped out almost his entire 2009 season.
"I'm very excited because I've waited for this moment for many years," the Dominican native said through interpreter Fernando Alcala. "I'm very grateful to be here."
Triunfel will become the youngest position player on the Mariners' roster, though he's two months older than Ramirez. He hit .260 with 10 home runs and 62 RBIs in 131 games in his first full season in Triple-A while playing shortstop and second base.
Carp had been on a rehab assignment after straining a groin muscle on Aug. 14, so he was activated from the 15-day disabled list. He hit .379 (11-for-29) with a home run and five RBIs during his seven-game rehab stint.
"I just want to stay healthy this last month," said Carp, who has had three stints on the DL. "I've been hitting it, swinging it, feeling really well at the dish. So I'm excited to get back. I didn't miss a beat hitting-wise. I feel great and just want to help out any way I can."
Wells was sent down to Tacoma on Aug. 27 when the Mariners activated Franklin Gutierrez. He hit .273 (6-for-22) with a home run, a triple, five walks and seven runs scored in six games. He was inserted immediately into Tuesday's lineup in right field against Red Sox left-hander Jon Lester, who he made his Major League debut against in 2010 with the Tigers.
Kelley was also sent down in mid-August and didn't allow a run in 5 1/3 innings in five relief appearances, giving up just two hits with no walks and six strikeouts and recording two saves. But he was hit in the elbow by a line drive on Aug. 29 and didn't pitch again until throwing to one batter -- and getting a strikeout -- in Monday's finale in Fresno.
"It was a screamer," Kelley said. "It came back faster than I threw it. Hit me right on the bone. But I threw to a hitter yesterday and everything was good."
Liddi, who opened the season with the Mariners, hit .270 with 11 home runs and 30 RBIs in 76 games with Tacoma.
Noesi also spent the second half of the year in Triple-A after struggling as a Mariners starter with a 2-11 record and a 5.77 ERA. He finished 2-6 with a 5.74 ERA in 11 starts for Tacoma.
Manager Eric Wedge said Noesi and Ramirez would work out of the bullpen for now and he doesn't foresee going to a six-man rotation at any point in the final month. Getting playing time for all his newcomers will be a challenge.
"We're here to win ballgames and we're going to put the best lineup for us to win," he said. "Along with that, we'll try to give guys any opportunity we can within those guidelines. But obviously we've got a lot of position players here and you can only do so much with it. We'll do the best we can."
