MIAMI -- The Marlins set their 25-man roster on Sunday morning. Among the notable surprises is lefty reliever Mike Dunn will open the season on the disabled list with a left forearm strain.
Before the noon ET deadline to set their Opening Day roster, the Marlins announced they have selected the contracts of relievers Craig Breslow, Dustin McGowan and Chris Narveson. The club also designated left-hander Brad Hand and outfielder Cole Gillespie for assignment.
Carter Capps, the hard-throwing right-handed reliever, had Tommy John surgery on March 8, and he will miss the entire season. Capps has been placed on the 60-day disabled list. Reliever Raudel Lazo will begin the season on the 15-day DL with a left shoulder strain.
Dunn and Lazo are on the disabled list, retroactive to March 25. The earliest either one can be reinstated is Saturday, when the Marlins are at the Washington Nationals.
Lazo is expected to open the season at Triple-A New Orleans.
Dunn threw 4 2/3 innings during Grapefruit League games. The 30-year-old has been one of the most dependable and durable relievers in franchise history, appearing in 354 games -- second most of any Marlins pitcher. Braden Looper holds the franchise mark of 368 games. He made 72 appearances in 2015.

Dunn, who has never been on the disabled list in his career, is not expected to miss substantial time. The lefty and the club are being cautious.
"He pitched in an 'A' game on the 24th," president of baseball operations Michael Hill said. "No issues. He was pitching on the back field and felt some tightness in his forearm. He had been throwing changeups -- and so we didn't think much of it. We didn't think much of it at the time.
"As we got into this last week, the tightness wasn't resolved. We got a MRI. The MRI was clean. No issues at all with the MRI. But when we got here to Marlins Park, the first day we were here for the intrasquad [game], the tightness hadn't really resolved [itself]. And with the season and the fact he hadn't pitched in an 'A' game before the 25th, we had the retro days, so we opted just to DL him and make sure we get it all out of there and he's fine for the long haul."
Breslow and Narveson are now the lefty setup options. The club opted for the two over Hand, who has been on the roster since 2011. Hand, who was out of options, has a 9-25 career record with a 4.71 ERA in 90 games, including 43 starts.

The decision to designate Gillespie was a tough call, because he plays all three outfield spots and showed in 2015 he can be valuable off the bench. But the team decided to go with Derek Dietrich, who also is out of options.
Miami, which opens on Tuesday against the Tigers at Marlins Park, is carrying 13 position players and 12 pitchers.
The regulars are J.T. Realmuto (catcher), Justin Bour (first base), Dee Gordon (second base), Adeiny Hechavarria (shortstop), Martin Prado (third base), Christian Yelich (left field), Marcell Ozuna (center field) and Giancarlo Stanton (right field).
The backups are Jeff Mathis (catcher), Chris Johnson (infielder), Miguel Rojas (infielder), Dietrich (infield/left field) and Ichiro Suzuki (outfield).
The rotation is: Wei-Yin Chen, Jose Fernandez, Adam Conley, Tom Koehler and Jarred Cosart.
Miami is carrying seven relievers: A.J. Ramos (closer), Bryan Morris, McGowan, Breslow, Narveson, David Phelps and Edwin Jackson.
