Year in Review:
Nunez was traded to the Marlins before the 2009 season and took over closing duties when Matt Lindstrom went on the DL in June. Nunez maintained that role for the remainder of the season, even after Lindstrom returned. He got 26 saves and blew seven saves, but did so with an ERA of 4.06 and an xFIP of 4.41. That is an underwhelming ERA for a closer; it ranked 21st among the 23 pitchers with 25 or more saves in 2009. Nunez gave up more walks (3.5 per nine innings) and homers (1.7 per nine) than the average pitcher – which includes starting pitchers – while only striking out slightly more than average (7.8 per nine).
The Year Ahead:
Nunez will start the season as the Marlins’ closer, and with Lindstrom traded to the Astros, his position is that much more secure. Still, he is probably one of the worst of the 30 probable closers starting the season. He should post an ERA around 4.15, a WHIP of 1.28, and get about 50 strikeouts in 60 innings. That is not bad performance, but compared to the projections for other closers it puts him near the bottom of the list. On the other hand, most of his value will come from saves, and he could easily get 25 to 30 as the Marlins’ closer. But because he is not a great reliever it is very possible he has a rough patch, loses the role, and does not get that many saves. (Dave Allen)
Nunez has had an interesting career, having been traded straight up for both Benito Santiago and Mike Jacobs. He has been the Marlins' closer for two years, and he was much better in 2010, with improvements across the board in his strikeout, walk, and home-run rates, even though he lost the closer role to Clay Hensley after an awful August. If anything, his FIP suggests that he may have gotten unlucky last year, victimized by a high BABIP, though that may be offset if his fly-ball and homer rates return to their previous levels. Obviously, his fantasy value is almost entirely tied to his save total, and while the Marlins appear willing to give him back the job, manager Edwin Rodriguez clearly has no problem giving the ball to someone else. Nunez may have suffered from fatigue last year, so the team may be more restrictive with his innings this year. If he can keep his strikeouts high and keep his BB/9 under 3.0, he'll likely remain effective. He isn’t exactly Robb Nen, but he’s good enough. (Alex Remington)
The Quick Opinion:
Nunez made improvements across the board in his strikeout, walk, and home-run rates, even though he lost the closer role to Clay Hensley after an awful August. He isn’t exactly Robb Nen, but he’s good enough.
Leo “Juan Carlos Oviedo” Nunez had three good seasons with the Marlins, but the honeymoon has come to an abrupt end. In the three seasons with the Marlins, he averaged 31 saves with a sub-four ERA. He did this by putting up a strikeout rate around eight and walk rate around three. Not ideal for an reliever, but his 92 saves with the Marlins was good enough for the eighth-highest total in the majors over the three-year period. Going into 2012, we don't know when J.C./Leo will be pitching, but we do know he'll be setting up Heath Bell in Florida when he gets here. His core stats are just not good enough to take a chance on without the saves though. (Jeff Zimmerman)
The Quick Opinion:
J.C. Oviedo/Leo Nunez has limited value until he returns to the country, which may take a while.
What was once a rose by another name has taken his time coming back from arm surgery and may soon be forgotten. But the artist formerly known as Leo Nunez should still have 94 mph gas and a strong change-up, and could at least be useful for holds in that Tampa bullpen. Too bad Grant Balfour and Heath Bell are probably ahead of him on the depth chart, even if he gets healthy. (
Juan Carlos Oviedo has had a balky elbow ever since his Tommy John surgery at the end of 2012 and actually spent more than a calendar year on the shelf with the Tampa Rays before he ever threw a pitch for them. He came out of the 2014 gate slowly, but put together a pretty solid May and June, compiling a 1.88 ERA over 24 innings pitched, mostly fueled by a .161 average on balls in play. He had one horrific relief appearance in August and was summarily kicked to the curb and never caught on with another team. He's now in the Dominican Winter League trying to hit the restart button. His velocity was off significantly last year, which is probably to be expected, but if it doesn't return and he can't muster better command than the unseemly 11.4% walk rate last year, he might just be staying in the Dominican. Needless to say, he's highly unlikely to positively contribute to your fantasy squad. (
The Quick Opinion:
Rebranded as Juan Carlos Oviedo, the former Marlins closer Leo Nunez isn't likely to help your fantasy squad much, and it's possible he doesn't find a major league gig at all in 2015.
After serving as the Marlins closer from 2009-2011 under the name Leo Nunez, Oviedo lost two full years to injuries before contributing 31.2 innings in the Rays bullpen in 2014. Following an invitation to spring training from the Rangers in 2015, he was granted his release after failing to make the team. He's a long shot to pitch again in the major leagues. (Owen Watson)
The Quick Opinion:
Currently unsigned after not throwing a minor league or major league pitch during 2015, Oviedo -- approaching his age-34 season -- appears as if he might have reached the end of his playing career. He holds no fantasy value in 2016.
