NEW MLB Closer Watch

Every Team's Closers and Closers-in-Waiting

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

Astros Closer Watch

Veterans Chad Qualls and Jesse Crain are the top contenders to handle closing duties for the rebuilding (building?) Astros entering 2014, but as with most of the team, the more interesting talents to watch are younger and deeper in the system for now. If the team is serious about building around a young core (and they should be) then Josh Fields is probably the one to watch here.

Angels Closer Watch

The Angels just couldn't hold out any longer. After cobbling together a half-season in which they're barely hanging onto a wild-card spot, they pulled the trigger to bring in veteran closer Huston Street, who should finally provide some stability. The selection of hot but flaky arms behind him is probably enough to ride out the season, but this bullpen isn't as deep and rich as it once was.

Flores ★ AA
0.90 WHIP, 9.8 K/9

Athletics Closer Watch

The green-and-gold closer situation remains one of the least stable in baseball, quite literally by design. There are a half-dozen viable in-house candidates already, led by 2012 breakout Ryan Cook and often unhittable Sean Doolittle, but drop-in veteran Jim Johnson got the first shot at the job. No matter what happens in the spring, of course, the odds of a midseason Moneyball-style shakeup are always very, very high in Oakland.

1.08 WHIP, 11.3 K/9
Leone
1.60 WHIP, 9.9 K/9

Mariners Closer Watch

The man with the crooked cap should bring some stability to the Mariner relief corps, but the group of young, hard-throwing and wild arms behind him remains mainly unchanged from years past in Seattle. If they all mature just a little, this could be a good bullpen, but even once Rodney's experience is factored in, it's all still a pretty green group.

Feliz

Tolleson
1.16 WHIP, 9.6 K/9
Cotts LHP Tired

Rowen ★ AAA
1.21 WHIP, 5.1 K/9

Rangers Closer Watch

With Joe Nathan and Joakim Soria out of the picture (with both now pitching in Detroit) a fully-recovered Neftali Feliz is the best bet in Texas. If he stumbles, the still-deep Ranger bullpen also features lefty Neal Cotts and young righthander Tanner Scheppers, who looked very good last season, and the sometimes-starting Alexi Ogando to turn to, should things get ugly.

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 ScoutingBook.com. 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.
