Aardsma was designated for assignment by the Braves on Monday.

Aardsma has struggled through 33 outings this season with the Braves, giving up six home runs, accruing an ERA of 4.70, and blowing three saves in a matter of 30.2 innings. His demotion renders him useless in leagues that require players to maintain their status on the 40-man roster, and all in all he's a 33-year-old pitcher who could be seeing his career wind down.

Aardsma was blown up for five runs on five hits and two walks in Saturday's loss to the Phillies.

Aardsma was viewed as an outside candidate to assume closing duties following the season-ending injury to Jason Grilli and the trade of Jim Johnson earlier this week, but it no longer appears that will materialize. Even before getting torched by the Phillies, Aardsma was called upon to enter the game midway through the fifth inning, an indication manager Fredi Gonzalez isn't earmarking him for a late-inning role. Instead, Arodys Vizcaino looks like the odds-on favorite to step in as the Braves' closer.

Aardsma will be called up from Triple-A Gwinnett on Tuesday, Mark Bowman of MLB.com reports.

The 33-year-old Aardsma, who has 306.1 innings of big-league experience, recently opted out of a minor-league contract with the Dodgers. Although he hasn't put together a strong season in the majors since 2009, he has pitched well at the Triple-A level this year, posting a 2.29 ERA and 25:7 K:BB ratio over 19.2 innings. Aardsma will likely serve as a middle reliever, and he could pick up a few holds along the way.

Aardsma signed a minor-league contract with the Braves on Saturday, MLB.com's Mark Bowman reports.

Aardsma, 33, had posted a 2.41 ERA and .176 BAA over his 18.2 innings with Triple-A Oklahoma City in the Dodgers organization before he chose to opt out of his contract last week. The Braves would appear to have a more pressing need for bullpen help at the MLB level than the Dodgers, so while Aardsma will initially be deployed at Triple-A Gwinnett, it may not be long before he's added to the active roster.

Aardsma decided to opt out of his minor-league contract with the Dodgers on Thursday and will become a free agent, MLB Trade Rumors reports.

Aardsma had a 72-hour window around the June 1 opt-out clause in his contract, and elected to exercise it when the Dodgers failed to add him to their 25-man roster. The 33-year-old shouldn't have trouble latching on with another organization after posting a 2.41 ERA and 11.1 K/9 rate over 18.2 innings while serving as the closer for Triple-A Albuquerque.

Aardsma signed a minor league contract with the Dodgers on Sunday, Eric Stephens of True Blue LA reports.

Aardsma spent the majority of his 2014 playing time at Triple-A, and didn't fail to impress. Over 35 innings last season, he posted a 1.29 ERA and 1.06 WHIP while striking out 36. His biggest knock last season was his control, as the 33-year-old walked 17 over the frames. Aardsma will enter camp in 2015 with a chance to earn a spot in the bullpen with a strong spring training.

Aardsma will throw for interested in teams in Arizona next week with the hope of landing a new contract, Fox Sports' Ken Rosenthal reports.

Considering how well he was pitching at Triple-A last season, there will likely be a few teams interested in his services on a low-risk deal. Now 33, Aardsma's most recent productive big league season came back in 2010 with Seattle (49:25 K:BB in 49.2 IP, 3.44 ERA, 1.17 WHIP).

Aardsma, who has been out for the last two months following surgery to repair a torn adductor muscle, is expected to begin a rehab assignment by the end of the week, Derrick Goold of the St. Louis Post-Dispatch reports.

Prior to succumbing to the groin injury, Aardsma was making a strong case for a promotion to the big leagues, accruing a 0.91 ERA over 28 games with Triple-A Memphis. The veteran reliever has made significant strides in recent days, throwing two live batting practice sessions. It may not take much longer for him to slot back into the Memphis bullpen, and if he reclaims his earlier form quickly, look for him to be added to the St. Louis roster as a September call-up.

Steve Adams of MLBTradeRumors.com reports that David Aardsma has a May 15 opt-out date on his minor league contract with the Cardinals.

Considering his 1.98 ERA with 12 strikeouts over 13 2/3 frames at Triple-A Memphis, Aardsma seems likely to exercise the opt-out if he's not called up. Eric Fornataro and Seth Maness would be vulnerable to lose their bullpen spot if the Cards decided to promote Aardsma.

Cardinals signed RHP David Aardsma to a minor league contract.

Aardsma was just given his release by the Indians last Friday, so it didn't take him long to find a new opportunity. The 32-year-old posted a 4.31 ERA and 1.46 WHIP over 43 relief appearances for the Mets last year. He'll serve as bullpen depth in the minors.

Indians released RHP David Aardsma.

Aardsma requested and was granted his walking papers after he was evidently told he wasn't going to make the Opening Day roster. The 32-year-old should be able to find another job relatively quickly, though he might have to go to the minors.

Indians signed RHP David Aardsma to a minor league contract with an invitation to spring training.

Aardsma has an uphill battle on his hands to win a roster spot, barring injury, as he'll have to beat out Bryan Shaw or Vinnie Pestano for a bullpen job. Aardsma posted a 4.31 ERA and 1.46 WHIP over 43 appearances for the Mets last year. He hasn't been effective since he was a 28-year-old pitching for the Mariners in 2010.

Mets manager Terry Collins said during a radio interview on WFAN Tuesday that he will use a closer by committee while Bobby Parnell (neck) is out.

David Aardsma could be first in line, as he received a save chance last week with Parnell out (though he blew it). LaTroy Hawkins will also be in the mix, as will southpaw Scott Rice. It's not clear how long Parnell will be out.

David Aardsma blew a save chance Friday against the Royals.

Aardsma was called on for the save with Bobby Parnell sidelined due to neck stiffness, but after inheriting a one-run lead in the top of the ninth inning, he proceeded to load the bases before giving up a game-tying sacrifice fly to Lorenzo Cain. The Mets eventually won the game in the 11th inning. Aardsma has been very solid since coming up from the minors, but he looked a little amped up for the chance at his first save since 2010. With Parnell potentially out for the entire weekend, he might get another opportunity soon.

Mets manager Terry Collins said Friday that David Aardsma will close while Bobby Parnell (neck) is sidelined.

Some speculated on LaTroy Hawkins as a potential fill-in option, but Collins would prefer to keep him in the eighth inning. Parnell could miss the entire weekend, so Aardsma makes for a good short-term option in most fantasy formats.

Aardsma had been in negotiations with the Hanshin Tigers of Japan's Central League but ultimately decided to remain in the United States. The 31-year-old right-hander will try to work his way up to New York. He has made one appearance in the major leagues since the start of the 2010 season due to Tommy John reconstructive elbow surgery.

The Japanese website Sanspo.com reports that the Hanshin Tigers of Japan's Central League are trying to sign David Aardsma.

Aardsma requested and was granted his released from the Marlins earlier this week, and it was evidently so that he could sign overseas. The right-hander has appeared in just one game at the big league level over the last two seasons due to Tommy John surgery.
