As Aroldis Chapman inches closer to free agency, decision makers in Cincinnati must be getting uncomfortable. Chapman is signed through 2016. Should he remain healthy over the next two seasons, he will sign a record breaking contract for a reliever. Since they’re unlikely to re-sign him, there will be increasing pressure to trade him while his value is highest.

The scariest part is the state of the Reds bullpen – they have no obvious alternative to Chapman. Cincinnati is lucky. We live in an era where at least 75 pitchers meet the basic requirements of a closer (and that excludes non-major league talent). Replacing Chapman is next to impossible, but finding a viable closer is easy.

I’d like to talk to you about Dellin Betances.

Wait! Wait. No. No, I wouldn’t. I’d like to talk about Mike Podhorzer first. Mike has published a lot of great work covering the fundamentals of the xK% (and xBB%) metric for pitchers (and hitters), so if you are unfamiliar with or falling behind on his work, I recommend you first click here, here or here. But if you’re lazy, the short of it is: xK%, or expected strikeout rate, is an equation birthed from a linear regression that measures how a pitcher’s looking, swinging and foul-ball strike rates as well as overall strike percentage correlates with his strikeout rate. It doesn’t predict future strikeout rates as much as it retrospectively adjusts past strikeout rates; thus, it is a good tool for identifying pitchers who potentially benefited (or suffered) from good (bad) luck in a previous season – say, 2014.

Like many other metrics completely unrelated to xK%, however, there is evidence that certain players consistently out-perform (or under-perform) what their xK% rates predict their actual K% rates should be. (Mike alludes to this trend in his quip about Jeremy Hellickson, a xK% underachiever, in one of the articles linked above.) Similarly to how a power hitter will post consistently higher ratios of home runs to fly balls (HR/FB) than a non-power hitter, or how Mike Trout will probably post some of the highest batting averages on balls in play (babip) in the league for years to come, it appears there is some skill, or perhaps a particular characteristic, inherent to pitchers who consistently best, or fall short of, their xK% rates.

The Cubs entered the 2014 season without a bonafide closer, but they did a great job piecing together the puzzle. Hector Rondon received his first shot in the ninth inning on April 11 and began regularly saving games starting in May. Surprisingly, Chicago was able to develop a number of relievers to the point where they could be viable firemen. The bullpen should be a strength for the club as they try to turn the corner.

The Atlanta Braves can say they have one dominant bullpen arm in Craig Kimbrel. Beyond that, and this year’s squad is a bit more iffy. Last season the Braves pen was middle of the road with a combined 3.8 WAR, but when accounting for their second lowest in baseball mark of just 440.2 innings pitched, the ratio shows how well the staff pitched. Looking to this season, the fantasy options are more limited with the departures of David Carpenter, Jordan Walden and Anthony Varvaro, last year’s top three holds leaders in Atlanta. After Kimbrel the value drops off considerably, but there are other mildly interesting options to be had.

It’s hard to overstate just how good Craig Kimbrel has been for his career. His ups-and-downs have consisted of a seasonal worst 2.48 FIP in his rookie season where he threw all of 20.2 innings. Sure, Kimbrel was a bit fortunate with a .235 BABIP and 0.29 HR/9 rate last year, just know that his 1.61 ERA and 1.94 SIERA were no flukes compared to his other seasons. If Kimbrel is your first pitcher — not just reliever — drafted and it happens in the fourth round, you can do just fine. Read the rest of this entry »

On Friday I wrote the following on Kyle Gibson in my Quick Looks piece:

He increased his Zone% a bit from 2013 t0 2014 (41.9% to 43.6%) and saw his K% increase (12.2% to 14.1%) and BB% drop (8.4% to 7.5%).

While, it may seem intuitive that throwing strikes leads to better strikeout and walk rates, I have never seen it tested. I will remedy this issue right now.

As of this mid-February day, the Indians possess a coherent bullpen. They feature all the things you want from a relief corps – an elite fireman, lefty specialists, ground ball guys, and a long man with upside. There’s only one reason to worry. What happens if their best hurlers hit the disabled list?

The Marlins bullpen finished sixth in WAR among all big league teams last year, thanks to one of the most underrated closers in fantasy and a collection of effective setup men. Heading into 2015, owners looking to pick up both saves and holds should find reasonably priced options in Miami.

The Rays bullpen is confusing. It’s not that they don’t have good arms there—they have plenty of them;it’s just not clear whether management will deploy these arms in any predictable way to start the 2015 season. Things are further complicated by the fact that incumbent closer Jake McGee had arthroscopic elbow surgery to remove “loose bodies” in mid-December and projects to miss most of April. (Though he might return sooner than originally expected.)

The Brewers lost half of what was a decent bullpen to free agency (Francisco Rodriguez, Zach Duke, and Tom Gorzelanny) and trades (Marco Estrada) this offseason and would enter the 2015 season pretty thin as currently constituted. That makes Milwaukee a relief corps in flux for fantasy. K-Rod recorded 44 of the team’s 45 saves last season, and Duke earned 1.3 WAR in a dominant campaign that featured 11.4 strikeouts per nine, which placed him in the top 25 of relievers with at least 50 innings pitched last season. Duke is now a White Sox and cannot return, but K-Rod remains unsigned. His return would mute much of the intrigue that centers on a likely new old closer.

Along with the xK% formula I devised and updated last year, I also developed an xBB% equation. Unfortunately, it isn’t as good as the expected strikeout rate formula, as our community has really struggled to determine how the various underlying skill metrics should interact to result in an expected walk rate. That said, my version is still the best I’ve seen, so it’s better than nothing. But there are seemingly consistent underperformers and overperformers, so don’t take a pitcher’s xBB% as gospel.
