Its not that often that I feel like the scales have fallen from my baseball eyes, but it just happened, and I’m excited to share why. It’s not that this one thing Explains All Baseball, but the effect seems to be enormous: whether or not a pitch has a platoon split has much to do with how vertical the movement

We know that the Diamondbacks’ rotation will be better in 2016. Part of that is because it would have been hard to be worse, but there have also been some notable additions. You may have heard about this. I’m guessing you did. For a team with big aspirations, a boost to the rotation was at the top of the holiday …

They say you have to have at least two pitches to make the majors. Three if you want to start. Having any number of “average” major league pitches is impressive, really, but they’re certainly not all created equal. Some guys have one “plus” pitch they can lean on to get the job done most of the time – a pitch …

Pretty often here on the internet we talk about non-elite pitchers as being more or less crap shoots. It’s true, pitchers tend to be more volatile than hitters, mostly because they get hurt more often. Luck can swing an ERA pretty wildly and trying to make bets on run-of-the-mill pitchers is just hard to do in confidence. What will Chase

The D-backs have a great young team of position players, and the makings of a pitching staff that could be at least solid. With the team on the upswing and organizational memory of .500 seasons in both 2013 and 2014, it’s easy to focus on how high the team can go. That’s important, and maybe the most important thing. Still …

Let’s just skip the introductory paragraph. I’m not a fan of beating a dead horse and that’s what all of these starting pitching posts seem like after a while. The starters were 27th in WAR, 21st in ERA, 24th in FIP, 26th in HR/9, 22nd in BB/9 and 18th in K/9. That’s bad and …

In the first year of collecting exit velocities, we’€™ve uncovered a few truths. The first and most important, although also the most obvious, is that the old adage of “€œhit the ball hard and good things will happen” is consistent with the data that’€™s been recorded. When the ball is blasted to virtually any field, the odds of a good …

When the Wheels Fell Off of 2015

On September 17, 2015 By

Once upon a time, the Diamondbacks were a relevant baseball team. If it seems like that was a long time ago, it’s because it kind of was. If it seems like that wasn’t a long time ago, it’s because it kind of wasn’t. I don’t really know what that means – it was a middle amount of time ago? The …

The D-backs staff’s ground ball percentage has tailed off a bit from where it was earlier this season, but it’s still up there — 46.1%, ranked 12th — and that’s still some kind of small shock, considering it entered the season with a staff of fly ball pitchers. A huge part of that is the relentlessness with which they’ve pitched

Coming into this season, Rubby De La Rosa was heavily reliant on his four-seam fastball, adding a few sinkers in 2014 but really only using a slider and a change to break up the fastball monotony. Both of those secondary pitches tend to be the kind that you can only get away with throwing about 20% of the time, …

D-backs position players rank 3rd in the NL this season in FanGraphs’ version of Wins Above Replacement. Sure, they could be better — two teams actually are — but for a team that finished last in baseball just last year, that’s a pretty enormous accomplishment. Hitting is a big part of it. The D-backs currently have a 96 wRC+, and …

The Diamondbacks are not a particularly good team when it comes to pitching. By ERA, they rank 26th in the majors. Since we know that Chase Field punishes pitchers more than almost any other park, that’s probably not the best way to look at them. If we choose a defense-independent, park-adjusted metric, they’re basically the same, ranking 24th

If you look at ERA, Rubby De La Rosa has been pretty bad. That’s usually what we think anyways when we see an ERA hovering around five. And if that’s of concern to you, perhaps you’ve also asked yourself why he’s even still in the rotation. Survivorship is a big part of it – he hasn’t missed a start – …

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 …

And things were going so well. After a sweep at the hands of the Pirates, the D-backs stand with an 8-10 record a little over a tenth into the season, more or less on the 70-something pace for wins that we might have expected coming into this season. If there’s any consolation, the pitching has been not just better than …

On Tuesday, Rubby De La Rosa started for the Diamondbacks. It was Arizona’s second game of the season. That made De La Rosa the D-backs’ number two starter, kind of. At least that’s how people thought of it, and when they did, a lot of them said, “hey, Rubby De La Rosa is our number two?” to which others responded, …
