Tracking Every MLB and Minor League Bullpen

We track and display a selection of closers, setup men and possible closers-in-waiting in major and minor league ball. We hope this helps you identify everything from individual opportunities for vulture saves to the entire future of your home town franchise, all in a single glance.

Astros Closer Watch

The precocious Houston Astros, already tasting a pennant, bolstered their already-great pitching in the offseason, bringing in top-shelf Phillies closer Ken Giles to slot in front of stalwart relievers Luke Gregerson and Tony Sipp. Josh Fields and Pat Neshek are longshot closer candidates here, in the event of a major earthquake, with more intriguing long-term options still on the farm.

Angels Closer Watch

The Angels have one of the weaker farm systems in baseball, but at least they have one of the league's most stable closers in Huston Street. He won't strike out as many as other closers, but at least he's reliable. The very capable but more erratic Joe Smith will loom behind him, followed by Fernando Salas and a raft of maybe-soons. If the top three falter, making sense of this situation will be anyone's guess.

Athletics Closer Watch

It's fun watching the Oakland Athletics develop closers, then trade them to the rest of baseball for more important parts. This year the team is showing surprising continuity (at least early-season continuity), though, by retaining Sean Doolittle and Ryan Madson for the beginning of the year. John Axford and Fernando Rodriguez are here, too, though they're really just bullpen padding for the short-term. The team's minor league system is full of options for the second half, once the team has presumably purged its bigger names and cleared the way.

Mariners Closer Watch

After a season of late-game breakdowns and general disappointment, the Seattle Mariners roster underwent the equivalent of a mid-level purge in the winter, as new management worked within a limited budget to shore up the team's second-line players while leaving the core largely untouched. In the bullpen, however, they made real changes, bringing in veteran closers Steve Cishek, Ryan Cook and Joaquin Benoit to qualify for the ninth inning job (it's probably Cishek's to lose first). The team also returns veteran performers Charlie Furbush and Vidal Nuno in support. On a team full of veterans, in fact, only young Tony Zych and new Mariner Nick Vincent look like dark horse future closers.

Rangers Closer Watch

The Rangers seem content to return the closer job to 2015-sensation Shawn Tolleson, and why shouldn't they: the youngster, after a couple of invisible seasons in LA, has really blossomed in Texas. Should Tolleson fade back into some sort of west-coast mediocrity, Keone Kela is the best arm behind him, though ex-Mariner ex-bartender Tom Wilhelmson has more experience and more of that ever-elusive closer mentality. The uncharacteristically-deep Ranger farm system also offers a solid half-dozen options for the second half, which means this bullpen could be a work in progress all season long.

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.
