There aren’t a lot of ways to predict closer change. Don’t go looking at ERA, projected or past, it’s not useful. Nor are three-Year Fielding Independent Pitching stats, even if those give you a bigger sample. Experience closing? Nah. Shutdown percentage? Nope. It’s not even important whether the pitcher was the favorite or a bullpen committee member. Depth of arsenals — and platoon splits on pitches — seem important, but aren’t really.

These things don’t seem to matter much when it comes to closer changes.

The list of things that might matter is super short, and the effects not so large that you’d want to stake your life on them. Reliever strikeout rate and velocity is important — new closers have higher rates and more velocity than the closers they replace, at least. Closers have slightly more experience in general (they are older). And lefty closers are about half as likely as you’d expect given the population of lefties in the game. Closers usually come from the end of the bullpen, so role is important.

We could use these facts to create a list of relievers that might close this year, really. If you then somehow controlled for the excellence of the closer in front of them, you could even sort this list for likelihood of change. Then we’d have the Non Closers Most Likely to Close This Year. Seems possible.

Valuing injured pitchers who plan on returning at a later date can be tough to do correctly. Yu Darvish an example of such a pitcher. After having Tommy John surgery in mid-March this past season, Darvish should return some point after mid-May (14-month rehab is the norm now). An owner can expect above replacement level from Darvish, but for a couple months, a lesser pitcher will be used. I will step through the process of valuing Darvish by combining his value with a replacement level pitcher.

It’s best of and worst of week at RotoGraphs. I’m here with 2015’s worst starting pitchers.

There’s a lot of ways to approach this. A lot of pitchers’ values are conditional upon their circumstances, so I’ve tried to keep this in mind when creating this list. When it comes down to it, though, this is all just one man’s opinion.

Fantasy Pros calculated the aggregate average draft position (ADP) using several premier fantasy baseball websites, so that’s the value upon which I’ve based my decisions.

But first, let us acknowledge 2015’s All-Injury Sigh Young Squad:

• He allowed a two-run homer to Lucas Duda, but Ken Giles otherwise held on for his 14th save of the year. Giles was a top tier non-save relief option last year and he’s kept it up this season while accumulating saves. His K% dropped to 29.6% from a ridiculous 38.6% last year but a 30% strikeout rate is still elite and although he’ll continue to close on the Phillies, Giles should be a prime target in 2016.

• Although Matt Williams let Jonathan Papelbon stay in the game after his throat grab on Bryce Harper, he’s now been suspended by the Washington Nationals for four games. Other people have been discussing the fight all day so I’ll only talk as it relates to the bullpen. I wouldn’t necessarily expect Papelbon to be welcomed with open arms after his suspension is over so his days of closing might be done this season and possibly even next year as well. I’ve removed him from the grid, putting Casey Janssen in his place. Matt Thornton threw a scoreless ninth today in a four-run game and could also be used in the ninth in Papelbon’s absence.

It’s September, so innings limits, pitch limits, etc. tend to be a topic of discussion. Some teams are going the way of a six man rotation a la the Mets (well, until Matt Harvey gets shut down for the regular season) or moving starters to the bullpen such as the Nationals and Joe Ross. Regardless of the route teams decide to opt for, here are a few relievers who I suspect will get at least one or two starts in the final weeks.

Tyler Lyons, Cardinals — This is the first name that jumps to my mind when I think of RP/SP guys. He’s already made seven big league starts, and while the Cards aren’t set on a hard limit for Carlos Martinez, both he and Jaime Garcia would probably benefit from an occasional extra day or two of rest, or even a skipped start. Lyons is largely unowned, and is available in over 98 percent of CBS, ESPN and Yahoo! leagues. For someone who owns a 8.07 K/9 (20.2 percent) and a 4.39 FIP/3.91 xFIP in 100 1/3 innings career as a starter, he has uses in deep leagues where you’re looking for a win.

A couple of weeks ago, I investigated Justin Verlander’s resurgence. I found reasons to validate his hot streak but turned up additional question marks along the way.

One of them was his zone contact rate (Z-Contact%). At 79.7 percent, it would have been the second-lowest of his career by several percentage points (despite not performing “at peak”). However, I realize now, unfortunately, that I must have encountered a glitch in the leaderboards — his Z-Contact% as of August 21 (because the post, despite running the same day as his Aug. 26 start, was published prior to it) was 85.7 percent.

Regardless, it got me thinking what affects a pitcher’s zone contact rate because it correlates very strongly with strikeout rate (R-squared = .594). User DoubleJ speculated about the metric via comment on one of last week’s posts:

• Rough night for the Nationals pen against the Mets. With a six run lead in the seventh, Blake Treinen, Felipe Rivero and Drew Storen walked six batters, allowing six earned runs to blow the lead. In the next inning Jonathan Papelbon gave up the go-ahead homer to Kirk Nieuwenhuis. Jeurys Familia wasn’t perfect allowing a few baserunners but held on for his 38th save of the season. The Mets have done a nice job with their in-season additions this year and it’s no different with the bullpen where Addison Reed (two strikeouts in a scoreless seventh) and Tyler Clippard (two strikeouts in a perfect eighth) have helped strengthen the bridge to Jeurys.

A quick rundown of the early games as we head into September.

• With Brad Ziegler in need of rest after a rough outing on Monday, the Diamondbacks went to Dan Hudson for the save against the Rockies. After two hits, two strikeouts and an earned run, Hudson netted his third save of the year. Ziegler’s worm killing ways (73% GB%) are still first in line but Hudson has cemented his role in the pecking order if anything were to happen to Ziegler.

• After a throw back performance by Bartolo Colon (8 shutout innings, nine strikeouts, and five baserunners) Jeurys Familia was called on for the save. Familia wasn’t sharp, allowing three baserunners and an earned run but otherwise escaped with a 3-1 lead and his 36th save. Familia’s ERA has jumped since the first half but he’s actually pitching better of late with a higher K% and lower B% than he had earlier this season. On the year he has a 1.78/2.83/2.64 ERA/FIP/xFIP line and should continue to rack up effective saves over the last few weeks of the season.
