MLB Closer Watch 2015 NEW

Every MLB and Minor League Bullpen Situation

Who's closing, who's next in line, and who's a future sleeper? Our new expanded Closer Watch shows the up-to-date state of every bullpen in MLB and how it's been performing lately, all in a single glance.

Cubs Closer Watch

The new brains behind the new-look Cubs have announced that Hector Rondon will remain the team's nominal closer entering 2015, but his hold on the job can't be too firm. While Rondon's certainly adequate, there are four or five other pitchers here who could all do the job, making this one of the bigger question marks in baseball.

Reds Closer Watch

Aroldis Chapman, bionic face and all, remains the scariest figure in the Reds bullpen, at least when healthy. Sean Marshall and Manny Parra return behind him, too though the big fastball of Sam LeCure and the big pants of Jumbo Diaz may have supplanted them in the pecking order for now. This remains a great bullpen that deserves a lot of praise for what they've done so well for many years now.

Brewers Closer Watch

Late-2014 add-on Jon Broxton stepped in when the Brewers needed an arm the most, but the late-signing K-Rod should get the closing job here until and unless he stumbles. Lefty Will Smith and righty Brandon Kintzler are penciled in to work behind the big two, and either could take over in a real pinch. Of course, Jim Henderson and Jeremy Jeffress also have closing savvy and stuff to burn, themselves, if not the cleanest track records.

Pirates Closer Watch

Mark Melancon bumped Jason Grilli from the closing job in Pittsburgh last season, and hasn't really looked back since. He seems likely to remain dependable, if not quite elite, in 2015, as well. The mix of arms behind him is solid, with both youth and experience on offer, and should keep the Pirates in a playoff chase deep into the year.

Cardinals Closer Watch

Trevor Rosenthal seems to have settled into closing for St Louis, which is probably a very good thing. The team added ex-Angel/Brave Jordan Walden as a setup/insurance reliever, and brings back most of the young stable that's kept the team contending year after year. Carlos Martinez will get another chance to stick in the rotation this year, but has to be kept in mind as always available for relief work, as well.

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.
