Diamondbacks Closer Watch

Veteran Brad Ziegler rose to semi-glory as the Arizona closer last season, turning a churning situation into a pretty stable one by the end of the year. Still, the Diamondback signing of veteran closer Tyler Clippard must keep Zig on the edge of his seat, huh? Daniel Hudson and Randall Delgado are probably just hiding in the corner, waiting for the two dragons to eat each other.

Rockies Closer Watch

In a normal world, Adam Ottavino, Chad Qualls and Jason Motte would all be competing for the closer's job in Colorado right now. But this is not a normal world. It is a world in which the basement-dwelling Rockies made a winter move to add superlefty Jake McGee, whose value to the team must be... as a midseason trade chip? In which case, coming this summer: Jairo Diaz is a sane man on a crazy, crazy planet.

Dodgers Closer Watch

Kenley Jansen, one of baseball's very best, is a lock to close for Los Angeles again in 2016. Behind him, Chris Hatcher and Yimi Garcia are big VORPs as setup arms, with loose cannon Pedro Baez and stinkballing lefty JP Howell also available, and any of those four capable of filling in, should Jansen somehow fall. On the farm, the Dodgers have their traditional bevy of 100mph options, highlighted by Frankie Montas, a kid who looks ready to close ballgames tomorrow.

Padres Closer Watch

Hand to our hearts and arrows to the sky, we couldn't be happier here at Scouting Book to see Fernando Rodney return to closing MLB ball games, and we'd like to thank the Padres for making it a possibility again. The very colorful Rodney should have the first shot at this wide-open job, but should he exhibit his more… exciting… style of pitching again, Nick Vincent or Drew Pomeranz look like long-term closers from here, while Kevin Quackenbush looks to return from a lost year, and a number of intriguing options ripen on the farm longer than they really need to.

Giants Closer Watch

The Giants bullpen underperformed in 2015, but returns largely unchanged this season. That might speak to a paucity of quality arms in the trade market, or maybe just to management's faith in Santiago Casilla and Sergio Romo. That tandem, at their best, can be one of the nastiest in baseball, but they need to click at the same time for that to happen. Behind them are the hard-throwing Hunter Strickland, lefty-threat Josh Osich, and a handful of reclamation projects and rising prospects that could liven up this bullpen by midseason.

Scouting Book Home Page

Closer Watch key and words of caution: Bolded names are best-bets to be closing for the immediate future; other pitchers are sorted from backup options right now (usually setup or short-relievers) to less-likely or future candidates. The order is hand-chosen and updated only every week or two based on who we would bet on, ourselves, for the future. Data is much more current than commentary, and readers may draw their own different conclusions based on the data displayed here or elsewhere. Game by game graphs show up to ten most recent outings for each pitcher, scored from poor (one red dot) to excellent (four green dots), based on counting stats, with special bonus points for saves and holds. Closers with more than a couple of red dots probably won't be closing much longer. Rate stats are shown for up to ten of a pitcher's most recent outings. Players whose most recent outing was in the minor leagues are labeled with the level of that most recent appearance. A gray star indicates a prospect who is also tracked as a prospect at Disabled List status is courtesy published MLB information and may lag behind conventional wisdom by a day or two. Pitchers who have thrown two, three or more days in a row, including yesterday, are flagged as 'Tired'. Data auto-publishes several times per day from Scouting Book's own data feeds, but can lag behind reality, and sometimes gets further delayed by gremlins, especially when feeding after midnight.
