Miami is "holding off" on attempting to add a reliever until after Carter Capps meets with Dr. James Andrews on Monday, according to Barry Jackson of The Miami Herald.
Capps, who entering Spring Training was expected to compete for the closing job, underwent an MRI on his right elbow earlier this week, The Herald reported.
When news of Capps' potential injury surfaced Tuesday, the Marlins were reportedly considering trading for a reliever. However, it appears the club is complacent waiting until after Capps' visit with Dr. Andrews to discuss whether or not to make a move.
Capps has been plagued by elbow injuries in the past and since he has the ability to be a successful major league closer, the Marlins are rightfully being cautious. Nonetheless, opening the season with Capps on the disabled list would be a big blow to a bullpen that finished the 2015 season 14th in bullpen ERA.
If Capps is expected to be out for an extended period, the Marlins will be forced to turn to their depth and numerous non-roster invitees.
Bryan Morris and Mike Dunn are both likely to open the year in the Marlins' bullpen but might be the only locks.
Kyle Barraclough, who the Marlins acquired in the Steve Cishek deal, is projected to be a back of the bullpen arm and could be used in a setup role in 2016. He had success in a short stint with the Marlins last season, pitching to a 2.59 ERA over 24.1 innings.
Prospect Brian Ellington also pitched to a 2.88 ERA over 25.0 innings with the Marlins in 2015 and could earn a bullpen spot with a solid spring.
If Edwin Jackson does not win a rotation spot, he will likely be pitching in relief. David Phelps is expected to serve as the club's long reliever and has proven to be valuable in that role.
Among the non-roster invitees, Craig Breslow could be the favorite to win a bullpen spot. He struggled with the Red Sox last season, pitching to a 4.15 ERA over 65.0 innings but is viewed as a bounce back candidate.
Miami does not have a notable amount of depth, so it follows the club is not in a hurry to make a trade. However, if Capps is not healthy and they run out of options, the Marlins might have to.
