Rays manager Joe Maddon said he's not giving up hope of Juan Carlos Oviedo (visa problems) cracking Opening Day roster.

The right-hander is stuck in the Dominican Republic due to visa problems. Oviedo, formerly known as Leo Nunez, spent the 2013 season rehabbing from Tommy John surgery. He's been limited to just three rehab innings over the last two seasons. His odds of breaking camp with the big squad are growing bleaker by the day.

Juan Carlos Oviedo has not yet arrived at Rays' camp due to visa issues.

Fellow reliever Juan Sandoval is also stuck in the Dominican Republic because of visa problems. Oviedo has been limited to just three rehab innings over the last two seasons due to injury, so the Rays are surely hoping to get a look at him soon.

Rays re-signed RHP Carlos Oviedo to a one-year, $1.5 million contract.

The deal is now official. Oviedo, formerly known as Leo Nunez, spent the 2013 season rehabbing from Tommy John surgery. The deal includes another $1.4 million with incentives, so he could max out at $2.9 million if all goes well. He could be in the mix at the closer role for Tampa Bay next season, though the recently-acquired Heath Bell might be the favorite.

According to Chris Cotillo of MLB Daily Dish, Juan Carlos Oviedo is expected to receive a major league contract from the Rays.

The deal won't be announced until later in the week, and terms of the contract have yet to be disclosed, but it will presumably be for less than the $2 million option the Rays declined. With the uncertainty at the back of the Rays bullpen, it's not unthinkable that Oviedo could work his way into save opportunities at some point this season.

Marc Topkin of the Tampa Bay Times reports that the Rays are set to re-sign Juan Carlos Oviedo.

No official word yet, or contract terms have been disclosed. The artist formerly known as Leo Nunez spent the 2013 season rehabbing from Tommy John surgery. With the recent success that the Rays have had in reclamation bullpen arms, he could prove to be a very nice low-cost addition.

Rays declined RHP Juan Carlos Oviedo's $2 million option for 2014.

They'll pay him a $30,000 buyout instead. Oviedo missed all of this season while coming back from Tommy John surgery and had lat issues during his rehab. Assuming he's healthy, the man formally known as Leo Nunez could prove to be a nice under-the-radar bargain on a one-year, incentive-laden deal.

Rays activated RHP Juan Carlos Oviedo from the 60-day disabled list.

He's now on the 40-man roster again, though he could be back off it quickly if the Rays decline his $2 million option for 2014. Oviedo missed all of 2013 while coming back from Tommy John surgery and had lat issues during his rehab.

Juan Carlos Oviedo (elbow) had to be shut down from throwing for a few days recently because of lat soreness.

It doesn't appear to be a major setback, but it won't help Oviedo's chances at returning next month to fill a role in the Rays' bullpen. Tampa would probably view his return as an unexpected bonus at this point.

Juan Carlos Oviedo (elbow) has begun throwing to hitters.

Oviedo's recovery from Tommy John surgery is coming along slowly but surely. The reliever is hoping he'll feel well enough to join the Rays' bullpen sometime next month.

Juan Carlos Oviedo (elbow) threw a bullpen session on Sunday.

It's his first since last September's Tommy John surgery. It's possible Oviedo could make it back to the Rays' bullpen late in the season, but they signed him in hopes that he could contribute in 2014.

Rays purchased the contract of RHP Juan Carlos Oviedo, placed him on the 60-day disabled list with a right elbow injury.

Oviedo is working his way back from Tommy John surgery and will miss most, if not all, of the 2013 season. The Rays obviously have decided he's worth hanging onto in hopes he can contribute in 2014.

The Rays have told Juan Carlos Oviedo that he will be added to the 40-man roster.

Ovideo, formerly known as Leo Nunez, had Tommy John surgery last September and is unlikely to pitch in the majors this season. The Rays will stash him on the 60-day disabled list.

Rays signed RHP Juan Carlos Oviedo to a minor league contract.

Oviedo underwent Tommy John reconstructive elbow surgery in September 2012 and probably won't be recovered until the very end of the 2013 season. The 30-year-old right-hander was formerly known as Leo Nunez.

Juan Carlos Oviedo underwent successful Tommy John reconstructive elbow surgery on Thursday morning.

Now begins a long road of recovery for the right-hander formerly known as Leo Nunez. He may be able to return near the end of the 2013 season if he avoids a setback.

Marlins transferred RHP Juan Carlos Oviedo from the 15-day disabled list to the 60-day disabled list.

The move cleared a spot on the 40-man roster. Oviedo was diagnosed with a sprained ulnar collateral ligament in his elbow in July and is scheduled to see Dr. James Andrews this week. It's possible he could need Tommy John surgery, which could put him at risk for missing the entire 2013 season.

Juan Carlos Oviedo will have his right elbow examined by Dr. James Andrews this week.

Oviedo was diagnosed in July with a sprained ulnar collateral ligament and apparently isn't progressing as well as hoped. It's possible Andrews could recommend Tommy John surgery, which would potentially knock the reliever out for the 2013 season.

Marlins activated RHP Juan Carlos Oviedo; placed him on the 15-day disabled list with a right elbow sprain.

Oviedo was activated because his eight-week suspension for falsifying his identity came to an end. However, he suffered a sprained ulnar collateral ligament in his throwing elbow during a tuneup outing in the minors and isn't expected to pitch this season. It isn't yet known if he'll opt for Tommy John surgery.

The Marlins don't expect Juan Carlos Oviedo (elbow) to pitch this season.

"This is not looking good for him to pitch for us this year," said Marlins president Larry Beinfest. "He was definitely in the plan. We anticipated him pitching for us. But right now we have to move ahead with the thought that he is not going to." Oviedo, formerly known as Leo Nunez, was diagnosed with a sprained ulnar collateral ligament in his right elbow over the weekend. It's not yet known if he'll attempt to rehab the injury or undergo Tommy John surgery, but odds are he has already thrown his last pitch as a member of the Marlins.

Juan Carlos Oviedo was diagnosed with a sprained ulnar collateral ligament in his right elbow.

Oviedo suffered the injury while pitching in the minors as he neared the end of his eight-week suspension. It's not clear if he'll attempt to rehab the injury or opt for Tommy John surgery, but he won't be joining the Marlins' bullpen in the near future. The Marlins moved to a closer-by-committee coming out of the All-Star break, but Steve Cishek is the pitcher to own at the moment.

Juan Carlos Oviedo is headed back to Miami after leaving Saturday's rehab game with Triple-A New Orleans due to right elbow discomfort.

He was making his third minor league appearance. Oviedo had hoped to return later this month and become part of the mix at closer for the Marlins, but obviously that's up in the air now.
