White Sox Closer Watch

The usually-contrarian White Sox went traditional by securing David Robertson to anchor the bullpen last season, and it paid off by giving the club at least one thing to rely upon: Robbie's 34 saves and 0.93 WHIP were as-advertised. He'll return, of course, backed up by the iffy-nasty mix of Jake Petricka, Zach Duke, Zach Putnam, and a mess of so-so options on the farm.

Indians Closer Watch

The underrated tandem of Cody Allen and Bryan Shaw has been one of the most reliable in baseball, but should that change unexpectedly, the Cleveland Indians have plenty more in store, with Zach McAllister, Jeff Manship and Dan Otero all looking closer-ish from time to time.

Tigers Closer Watch

The Tigers either bought-high on Francisco Rodriguez in the off-season, or downright stole him from the rest of the league. After some down years, K-Rod posted his best season of the last five in 2015, striking out 61 batters in 55 innings of work. If he's really back to form like that, he's a bargain. If not, the Tigers also have capable arms like Justin Wilson and Mark Lowe available, with the maybe-still-kinda-closer-of-the-future Bruce Rondon still on retainer.

Royals Closer Watch

The defending champs return the group that dominated baseball last season, with Wade Davis anchoring the bullpen that held the whole league at bay in 2015. Kelvin Herrera, Luke Hochevar and returned prodigal son Joakim Soria provide the nastiest depth (or is that the deepest nasty?) in all of baseball.

Twins Closer Watch

The under-appreciated Glenn Perkins will return to close in Minty Soda, with the ever-mercurial Kevin Jepsen behind him. Casey Fien, JR Graham and Trevor May look like the best bets after that. The Twins surprised many by competing into September last year, and while it's hard to think of them as repeating that challenge, they're clearly a better team than many believe, too. That makes any in-season moves hard to predict, though any any trade, whether made for now or for later, would likely involve a reshuffling of that bullpen depth.

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.
