My goodness, there are a ton of relief arms in camp this spring. I know, I know. This isn’t exactly unheard of as relievers, especially those not slated for late inning duty, are probably the most fungible assets in the game. They’re also the most volatile. With performances fluctuating wildly and sample sizes small, evaluating relievers is difficult in the …

How do you know if something is broken? Usually, you give something a go and don’t get the desired effect. Maybe you try again and still get an error. Other times, after a second try, everything works just fine. There always little blips on the radar of life. I mean, we all have to cycle our routers once in a …

A new year provides an opportunity for reflection. I was doing a bit of that recently, thumbing through some old episodes of The Pool Shot while being delayed at the airport again. The experience was fun and while I’d like to think we were right more than we were wrong, the episodes help harken back to a time that the …

One of my favorite debates within the baseball analytics community is how to evaluate pitching. We’ve collectively moved on from ERA since it has some obvious problems. The first is the most glaring: ERA tells most of the story of what happened, not how talented a pitcher is. We don’t really care what happened, we care mostly about how good …

Happy Memorial Day, folks, and enjoy the weekend. Here at Inside the ‘Zona, we’re getting an early start. The idea was to post some graphics in lieu of a post, and maybe add to that as the mood strikes later today, and over the weekend — I wouldn’t have written any kind of explanation here at all, but I need …

It’s a magical time of year, the time in which mountains are made of molehills, common sense proves evasive and The People generally freak out. The Diamondbacks have sunk below .500 for the first time in 2016 as of this writing (hopefully they’ve “surged” to even in the standing by the time of this reading) and we’re all basically doomed. …

Not long ago, we worked through some research that betrayed a general principle: the more horizontal the movement on a pitch, the more susceptible to large platoon splits it was likely to be. The converse — that when the movement of a pitch was more or mostly horizontal, the bigger the platoon splits — clashed with the D-backs’ sinker …

On Tuesday I previewed arsenal scores, a metric created by Eno Sarris at RotoGraphs. The idea is simple: evaluate each pitcher’s pitches based on swinging strikes (good) and ground balls (also good). Sarris was kind enough to share his data with Inside the ‘Zona I’ve used it already to showcase D-backs starting pitchers. Now it’s time to highlight the …

Earlier this week, we had some fun looking at the best and worst pitches from Diamondbacks starting pitchers in 2015. There were some really good pitches on disply there, even considering the struggles that the staff had last year. This time around we’ll position the microscope on the relievers, but there’s something notable to include here: relief pitchers have …

Last week in setting a benchmark for wins needed from the rotation, I used a placeholder for wins we could expect from the bullpen: about 2.5 above replacement. It was intended to be conservative, but if this season is any guide, the bullpen could be quite a lot better than catch-all statistics like Wins Above Replacement would indicate. As …

The D-backs are pitching differently this year. The trend showed up early: the staff was re-designed to become much more ground ball oriented, it seemed. Several pitchers are throwing more sinkers than they have in the past, and the grounders have continued. But more than anything else, as Jeff examined yesterday, the team is pitching down in the

A funny thing happened at the start of the season: even though the rotation was to be manned by three fly ball pitchers, by the end of April the D-backs staff was fourth in the majors in ground ball percentage at 49.1%. It wasn’t all Brad Ziegler. Archie Bradley was a big part of the sharp change in the …

It’s one week until the Diamondbacks take the field for Opening Day. Of course, that will be their second game of the season for them since they play on Opening Night against the Giants, but baseball’s right around the corner. Finally. And, with this being the final week without real baseball, everyone’s releasing their final predictions. The trend for …

When the Diamondbacks opened camp, they had a handful of lefties competing for spots in the bullpen to open the season. Oliver Perez was the only one with a firmly entrenched spot on the active roster. Robbie Ray, Vidal Nuno and Andrew Chafin were brought in to work as starters, but all have been considered for bullpen slots. Recent …

After the Wade Miley trade was completed, GM Dave Stewart indicated that Josh Collmenter, Jeremy Hellickson, Rubby De La Rosa and Allen Webster were penciled into the rotation. Let’s put problems with that aside and accept, for the moment, that that’s true — what can we expect for the fifth slot?

The leading contenders for that spot are …

While the Aces were largely an older ball club, they weren’t devoid of talent. Nick Ahmed, Andrew Chafin and the newly-acquired Zach Borenstein joined a group of veterans to lead Reno to the PCL Championship Series where they eventually lost to Omaha in five games. It was a fantastic season for Reno, one in which they scored a ton …
