The Phillies weren’t the only playoff contender to drop off the face of the earth in September. The land of the chimichanga fared no better in late-season play than the cheesesteak republic, leaving a foul aftertaste to what had been a solid season.

The Setup

Arizona went a new direction after 2016, replacing the general-managerial meanderings of Dave Stewart with the more modern approach of Mike Hazen, formerly under Dave Dombrowski and Ben Cherington with the Red Sox.

Hazen worked quickly, acquiring Ketel Marte and Taijuan Walker from the Seattle Mariners for Mitch Haniger, Jean Segura, and prospect Zac Curtis. But the 2017 season was largely based around the previous core, with Arizona signing several role players — but no big difference-makers — in free agency.

The inherited rotation combined for a 3.61 ERA and 18.8 WAR, that total ranking second in baseball behind only the Indians. Hazen did make one gigantic contribution in the form of J.D. Martinez, acquired from the Tigers in July.

As in-season trades go, the Martinez swap went just about as well as anyone could have expected. The primary starter in left field, Yasmany Tomas, had gone on the disabled list in June with a groin injurym and in truth, the team was already on the verge of giving up on him as a starter. The team’s lack of outfield depth was already glaring, with A.J. Pollock out and Arizona resorting to a Gregor Blanco/Rey Fuentes timeshare in center.

So correctly identifying the team’s biggest problem, Hazen closed a deal on the solution and Martinez paid off, hitting .302/.366/.741 for the team, with a ludicrous 29 home runs in 232 at-bats. The fact that the team’s OPS only improved by seven points in the second half of the season even with Martinez should be a fairly good indication as to the straits in which the offense would have found itself without the pickup. That Hazen managed to bring in Martinez without eviscerating the already suffering farm system was a coup.

The winter of 2017-18 presented the team with a significant problem in the form of contracts. With 16 players in their salary-arbitration years and five in arbitration for the first time, the roster was set to become more expensive without actually improving all that much.

In the end, the 2018 team would cost $40 million more than the 2017 version, and that’s with under $20 million of total spending in free agency, primarily in the form of Alex Avila and Jarrod Dyson.

Going into 2018, the primary questions about the team were whether the offense could survive J.D. Martinez’s departure with only Steven Souza added to the roster and how much 2017’s rotation would regress the following season.

The Projection

ZiPS didn’t see Arizona matching their 93 wins from 2017 but still saw them as the biggest threat to the Dodgers, with a projected 86-76 record and 13% chance of winning the division. The projections were generally optimistic about the rotation staying one of the top groups in baseball, but was much less sanguine about the offense, seeing it as a below-average unit despite Paul Goldschmidt’s best efforts.

The Results

In an abstract sense, Arizona had four seasons in 2018 rather than one, each with a different character and a grossly different set of results.

The Sprint (24-11)
The team started out absolutely blazing, not losing consecutive games until the back end of a four-game split with the Dodgers in May. The pitching went 20-8 with a 2.96 ERA and 280 strikeouts in 255.1 innings, almost looking like a Randy Johnson Cy Young campaign (though, technically, with fewer strikeouts).

There was one giant hiccup, though, in that the pitching was basically propping up the offense. The team won 24 of 35 because of that staff, but were hitting only .228/.311/.407 for the season, ranking 19th in OPS and 17th in runs scored. Those rankings were despite Goldschmidt’s .900 OPS and A.J. Pollock’s 1.021 OPS through the end of April.

What would happen to the offense without Goldschmidt and Pollock, even if they could maintain Cy Young-level pitching for an entire year? As you no doubt realize, I’m asking this question for a very specific reason.

The Wile E. Coyote (2-15)
One of the frequent gags in Wile E. Coyote cartoons features that same coyote — having just endured some mishap with an Acme-brand product — walking off a cliff into thin air and remaining aloft momentarily before realizing his predicament and plummeting to earth.

Pollock broke his thumb on the 15th, leaving the Diamondbacks again to scramble for a center-field replacement in-season. Fortunately, unlike past Diamondbacks teams, this one had prepared for such an event with the signing of Dyson the previous offseason.

It didn’t do the team any good in the end. Dyson didn’t hit at all, leaving a problem in center that wasn’t really resolved until Pollock’s return. But the larger problem was that nobody else hit, either. During these 17 games, the team slashed .182/.248/.291, and even Goldschmidt wasn’t much help.

Normally, there needs to be a lot of suck to go around when losing 15 of 17, but the pitching was absolutely fine. Not at April levels, but pretty good. The 2-15 record and 3.87 ERA they produced has a similar look to Jacob deGrom’s full-season line.

The Surprisingly Normal Period (48-35)
After a carnival-ride first two months came a decidedly normal stretch of the season. The rotation ranked 10th in ERA during this period, a little below where ZiPS pegged them, but amply compensated by the 3.44 ERA from the bullpen.

Even the offense showed a pulse. While Pollock struggled after his return from his thumb injury, hitting .234/.276/.318 through the end of August, the team had six players with at least 100 plate appearances and an .800 OPS in this mini-season: Goldschmidt (1.087), David Peralta (.978), Ketel Marte (.858), Steven Souza (.819), Daniel Descalso (.818), and Eduardo Escobar (.813). This was enough to rank Arizona eighth in runs scored, behind only the Dodgers, the Coors-inflated Rockies, and the Cardinals among NL teams.

The September Collapse (8-19)
On the morning of September 1st, Arizona was still leading the NL West by a single game. This was their last lead of the season, however — and, by the time they went to bed on the 2nd, they were in third place. On only one occasion did Arizona win consecutive games in September, helping the Rockies catch up to the Dodgers in the last week, but long past the point at which they could help themselves in any meaningful way.

Arizona hit .214/.287/.374 in September, Ketel Marte representing the team’s only bright spot at .301/.373/.562. The bullpen collapsed, allowing a .795 OPS en route to a 5.52 September ERA. As before, the starting rotation largely held up its end of the bargain — with the exception, at least, of Zack Godley, admittedly the rotation’s weak point most of the season.

What Comes Next?

The biggest problem the team faces is that the fundamental problems still remain. They still need to improve the offense while navigating significant payroll constraints. The farm system will take years to repair, so they can’t look for many quick fixes from that source.

Arizona already starts with a roster that’s somewhere around $140 million after the re-signing of Eduardo Escobar. This will come down somewhat with Shelby Miller almost certain to be non-tendered and Brad Boxberger a probability to follow Miller to free agency.

Even if we call it a $120 million payroll for the same team as last year but without Patrick Corbin and A.J. Pollock, that’s a dreadful place to begin an offseason.

The general feeling around baseball, one Arizona has done little to rebut, is that the team is headed for a rebuild. Goldschmidt is unsigned past 2019, and aging first basemen have a tendency to result in terrible contracts for the signing teams. Greinke’s survived the loss of velocity on his fastball, but he’s also a very expensive 35-year-old on a team without much payroll flexibility.

A lot of people are unhappy about the prospect of Arizona and Seattle entering rebuilding phases right now after their competitive 2018 campaigns, but they both share a similar set of problems: payrolls near their maximum willingness to spend combined with minor-league systems that can’t bridge the short-term gaps. Arizona can’t afford even to re-assemble the exact 2018 roster that finished barely above .500.

I don’t expect a full rebuild for the team to be as painful as these sometimes go. The club does have players that can be part of the future around which they build, including Marte, Walker, Robbie Ray, etc. Rebuilds like Houston’s are especially difficult because they weren’t started until after everything of value was gone.

Whether Arizona chooses to go the “let’s call a contractor” or the “cool, check out this WWI-era flamethrower we found!” path, the team is likely to finish 2019 with fewer wins than 2018.

Way-Too-Early Projection – Paul Goldschmidt

It’s not 2019 that’s possibly scary for Arizona and Goldschmidt; the short-term is not the question. What is scary, if Arizona did extend Goldy rather than trade him, is what his decline phase looks like. Age hasn’t been brutal to Joey Votto, but it’s taken a lot of star first basemen very quickly — and not just average guys, but legitimate mega-stars like Albert Pujols and Miguel Cabrera.

The projection highlights the quandary Arizona’s in. Goldschmidt has been — with the exception of a brief appearance from J.D. Martinez — the centerpiece of the D-backs offense. Losing him would be really tough. On the other hand, if Arizona’s internal projections are anything like ZiPS, they probably can’t sign him either — unless he’ll agree to a Carlos Santana-type deal rather than an Eric Hosmer one. So the idea of Goldschmidt starting 2019 wearing new threads is not far-fetched.

Scott Radinsky came into coaching with an old-school approach. That was to be expected. His playing career spanned the 1986-2001 seasons, and he honed his craft under the likes of Moe Drabowsky, who came of age in the Eisenhower era. Analytics were in their infancy. Radinsky was hired by the Indians in 2005 — initially to tutor pitchers in the minors — on the strength of his nuts-and-bolts knowledge and his communication skills.

The 50-year-old went on to serve as Cleveland’s bullpen coach in 2010-2011, and then as their pitching coach in 2012. From there he moved on to the Dodgers organization, and he spent the last two years as the bullpen coach in Anaheim. Along the way, he’s learned to embrace analytics.

“The information wasn’t as eye-opening to me when I was first getting exposed to it,” admitted Radinsky, who now monitors TrackMan data throughout the season. “I wasn’t resistant; it just didn’t make complete sense to me. But over the years, because of how much better it’s being explained — and a lot of it seems more quantifiable — it makes perfect sense. I’ve completely bought in, which makes it easier for me to sell something to a player.”

Radinsky gave examples of that salesmanship — we’ll share specifics in the coming week — including convincing Blake Parker to up his breaking ball usage, and getting Justin Anderson to better utilize his fastball. In each case, the data provided by Anaheim’s analytics department was delivered to Radinsky in “an awesome” manner. Just as importantly, it didn’t arrive heavy-handed. Read the rest of this entry »

Zack Greinke’s final start of the 2018 season was a tour de force, one that knocked his former team, the Dodgers, out of first place in the NL West heading into the season’s final weekend. The going-on-35-year-old righty survived a rocky beginning and pitched well, drove in the go-ahead run, tormented longtime nemesis Yasiel Puig as baserunner and a pitcher, and even made a nifty fielding play, albeit one that ultimately didn’t count. It was a fitting capper to a very good season in which Greinke made his fifth All-Star team and delivered solid — but not exceptional — value given his massive contract. He couldn’t singlehandedly pitch the Diamondbacks into the playoffs, and he isn’t likely to receive any Cy Young votes, but by staying healthy and pitching at a high level, he gave his chances at Cooperstown a considerable boost.

It’s that last topic that brings me to this post, because multiple readers have asked for it in some context. I’ve touched upon the cases of several of Greinke’s peers this season, such as Felix Hernandez (here), CC Sabathia (here) and Justin Verlander (here). As we’re about to spend the next five weeks absorbed in postseason baseball, it seems like a good time to check in.

But first, let’s appreciate the resiliency and athleticism Greinke displayed on Wednesday night. Peppered for seven hits from among the first 12 batters he faced, he managed to limit the damage to two runs thanks in part to a double play off the bat of Joc Pederson that ended the second inning and a diving stab by shortstop Nick Ahmed that snared Puig’s bases-loaded, 99.9 mph line drive to end the third. That out was part of a stretch in which Greinke retired 10 of the final 12 batters he faced, with a Chase Utley walk and a Cody Bellinger infield single the only blemishes. Ballinger’s single followed a grounder up the first base line that Greinke — a four-time Gold Glove winner who has seven Defensive Runs Saved to his credit this year — gloved and then flipped to first baseman Paul Goldschmidt in time for what would have been an out had the ball not been ruled foul:

On the other side of the ball, in the bottom of the second inning, as starter Ross Stripling coughed up the Dodgers’ early 2-0 lead, Greinke stroked an RBI single up the middle to plate Nick Ahmed with Arizona’s third run. He took second on a Ketel Marte single, and then tagged and went to third on an Eduardo Escobar liner to Puig:

On Sunday, the Rockies shut out the Diamondbacks 2-0, thus completing a three-game sweep in Arizona that put the home team out of its misery as far as the 2018 season is concerned. The Diamondbacks spent 125 days with at least a share of first place in the NL West this year, more than any other team, and when they weren’t in first they were at least in Wild Card contention. And then the calendar flipped to September, and they made like Wile E. Coyote:

From August 31 to September 23, the Diamondbacks lost 17 out of 22 games — that’s a half-game worse than the Orioles, who have already lost 111 games overall — producing a playoff odds graph that, as I suggested last week, looks more like the sharp spires of Utah’s Bryce Canyon than the signature expanses of Arizona’s Grand Canyon. (As a Utah native who has never hiked the latter, I may be biased here.)

Anyway, ouch. The collapse has to rate as one of the more gruesome in recent history, though it isn’t as though the team frittered away a seemingly insurmountable lead or was a powerhouse to begin with. The Diamondbacks’ largest lead in the NL West was six games, and that was as of May 1, when they had just beaten the Dodgers for the second straight night to open a four-game series and climbed to an NL-best 21-8. They have the NL’s fifth-worst record since then, despite outscoring the opposition:

That May 1 win was just one of eight the Diamondbacks notched that month en route to an 8-19 record. They rebounded to go 19-9 in June, but spent the next two months meandering around .500, going 13-13 in July and 14-12 in August. Even so, they were in either first or second place in the NL West for all but one day of that two-month span of mediocrity.

This year’s National League Cy Young race invites multiple interesting questions about how best to evaluate pitching performance. Jacob deGrom, for example, is the league’s leader in ERA by a healthy amount; however, he’s also recorded only as many wins as reliever Jeremy Jeffress. Max Scherzer is having another great season, but his .255 BABIP compels one to consider whether his 2.31 ERA is the product of luck or defense (although the Nationals have recorded below-average defensive numbers both by UZR and DRS). Aaron Nola, meanwhile, has recorded a similarly low BABIP even as Philadelphia has produced NL-worst figures both by UZR and DRS. Finally, while the race has been viewed as a three-person contest for some time, it’s also possible Patrick Corbin has inserted himself into the conversation with a fantastic second half.

Sorting through the candidates is difficult. Ultimately, one’s choice for Cy Young will depend on how one weighs what a pitcher can and cannot control — and how best to quantify those effects. To start, here are some general metrics that should be familiar to FanGraphs readers.

Based on these numbers, Jacob deGrom is the pretty clear favorite for Cy honors, with Max Scherzer an equally clear runner-up. What’s less clear, however, is that the results of a vote would produce a similar outcome, as both pitcher wins and other versions of WAR are likely to influence writers — and arrive at different conclusions than the figures here. Below, I’ve included some different versions of WAR, each of which paint the field in a different light.

Here we see a version of reality that suggests greater parity in the race. Averaging the numbers above, we’d still put deGrom first, Scherzer second, and Nola third, but Scherzer actually places ahead of deGrom in two of the four metrics, while Nola and Scherzer are more closely situated. Examining how each of WAR metrics arrives at its destination can help inform how to use them. Last week, Eno Sarris took a look at some of these same issues in a discussion of how large a role luck ought to play in Cy Young voting. There is also the question of what defines “luck” in the context of pitching, what sort of control a pitcher exerts over certain outcomes, and what role a a pitcher’s park ought to play in our evaluations of him.

The metrics above all feature different inputs which, naturally, lead to different results. In the version of WAR used at FanGraphs, those inputs are innings, strikeouts, infield flies, walks, and home runs — along with factors for league and park. DeGrom leads by this particular measure because his strikeout, walk, and homer numbers are all great. Scherzer has good walk and strikeout numbers but a closer-to-average home-run rate. Nola features slightly inferior (although still excellent) strikeout and walk numbers — plus a good home-run rate — but he falls behind Corbin, who has good numbers in all three.

The next metric, RA9, is another version of WAR carried at FanGraphs — one which, in this case, simply considers the number of runs a pitcher allows while also factoring for league and park. That’s how Nola, with the very good ERA, jumps up near Scherzer, though still short of deGrom. RA9 includes runs that were scored or not scored due to defense and sequencing, but does not try to make any adjustments for those factors.

Baseball-Reference begins with something like FanGraphs’ RA9 calculation but makes further adjustments for opponent and team defense, which is a significant factor in this year’s race. Nola tops the Baseball-Reference WAR leaderboard because of how well he’s prevented runs despite Philadelphia’s poor defense. Generally the effects of these defensive adjustments are muted, but because Nola appears to be headed for one of the 10 best bWAR seasons of the last 50 years, this case invites some scrutiny. Patrick Corbin suffers from the opposite scenario: Arizona has recorded strong defensive numbers, meaning he receives a “penalty” of sorts for his contribution to run-prevention.

Here are the overall team defense numbers by DRS, which Baseball-Reference uses, and UZR, which is included in WAR for position players but not pitchers here at FanGraphs.

There is obviously a much larger spread with the DRS figures, as defensive adjustments alone mean a difference of 24 runs between Nola and Corbin, which is about four times as much as the difference by UZR.

Over at Baseball Prospectus, their Deserved Run Average (DRA) metric accounts for as many aspects of a pitcher’s game as possible and attempts to factor for everything including park, opponent, catcher, umpire, and pitch effectiveness to determine how many runs a pitcher should have allowed with all those variables rendered neutral. By their methods, Scherzer leads over deGrom, with Nola and Corbin a ways behind.

There’s certainly an argument to be made for considering the strength of a defense behind a pitcher, and reason dictates that a defense can help or hurt a pitcher’s run-prevention numbers. Defense alone, however, isn’t going to fully explain the difference between a pitcher’s FIP and ERA. Luck is involved, as well. We can use Statcast information to determine just how much defense and luck might be involved, though it won’t do a good job separating those two factors. For starters, here are the xwOBA and wOBA figures for each of the pitchers above.

In terms of what a pitcher has deserved to concede based on quality of contact, strikeouts, and walks, Scherzer has gotten just about what we might expect, while deGrom and Nola aren’t far off expectations. Corbin is the outlier here, and there is a case to be made that Arizona’s defense is partially responsible for his good fortune. What’s interesting, though, is that Corbin’s ERA is actually much higher than his FIP. This could mean that Corbin has been rather fortunate this year on home runs or that the contact he’s conceded on balls in play has been of higher quality than the sort conceded by other pitchers.

We can remove the most skill-based aspects from above by taking out strikeouts and walks and looking at xwOBA on just batted balls.

Here we see almost no effect on Scherzer’s outcomes, with a slight benefit for deGrom and Nola, and then a big help for Corbin. You’ll note that the league-wide numbers are off by 15 points from each other, likely due to a potentially dead baseball, as the estimates on launch angle and exit velocity are based on previous seasons, when the ball was perhaps a bit more lively. As we are looking at numbers between pitchers in this season alone, the comparisons still provide value. What happens when we remove home runs and look solely at batted balls? See below.

In theory, these numbers factor in both defense and luck on batted balls this season. As we can see, it appears that, whatever poor defense has victimized Nola has likely been evened out by good fortune. The same is true for deGrom. Scherzer, meanwhile, appears to have received a slight benefit, with Corbin being the recipient of some good defense in Arizona. This probably doesn’t leave the reader with any definite conclusions. We have a better idea about the quality of contact and how defense might have affected run totals — which is to say not much — but the extent to which a pitcher exerts control over that contact is also a matter of debate.

If you believe that a pitcher controls very little of opponent contact — or, alternatively, are unsure of the level of control — the version of WAR hosted here at FanGraphs is your main resource. If you believe that a pitcher is wholly responsible for the quality of contact he concedes and also that defensive quality doesn’t move the needle much in one direction or another, RA9/WAR makes some sense for you. If you believe further adjustment needs to be made for defense, bWAR can provide some help. If you want a more granular look at individual pitches, DRA provides guidance. If you just want something based entirely on xwOBA, a crude attempt is made below.

While the question of value is somewhat objective, there is some subjectivity involved, but if making a decision on the Cy Young, it’s important to have as much information as possible to determine why one pitcher might be better than the other. It isn’t enough to simply prefer one stat over another and blindly rely on it because you generally agree with the methodology. Look at how the results are reached to make the best possible decision.

As promised in the final paragraph above, here’s a rough approximation of WAR based on xwOBA:

Notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Note from Eric: Hey you, this is the last one of these for the year, as the minor-league regular season comes to a close. Thanks for reading. I’ll be taking some time off next week, charging the batteries for the offseason duties that lie ahead for Kiley and me.

D.J. Peters, CF, Los Angeles Dodgers
Level: Double-A   Age: 22   Org Rank: 7   FV: 45+
Line: 4-for-7, 2 HR, 2B (double header)

Notes
A comparison of DJ Peters‘ 2017 season in the Cal League and his 2018 season at Double-A gives us a good idea of what happens to on-paper production when a hitter is facing better pitching and defenses in a more stable offensive environment.

Reports of Peters’ physical abilities haven’t changed, nor is his batted-ball profile different in such a way that one would expect a downtick in production. The 2018 line is, I think, a more accurate distillation of Peters’ abilities. He belongs in a talent bucket with swing-and-miss outfielders like Franchy Cordero, Randal Grichuk, Michael A. Taylor, Bradley Zimmer, etc. These are slugging center fielders whose contact skills aren’t particularly great. Players like this are historically volatile from one season to the next but dominant if/when things click. They’re often ~1.5 WAR players who have some years in the three-win range. Sometimes they also turn into George Springer.

No team plays a completely balanced scheduled over the course of a season. Some divisions, naturally, are better than others. Because intradivisional games account for roughly 40% of the league schedule, there is necessarily some irregularity in the strength of competition from club to club. Interleague play, which represents another 10% of games, also contributes to this imbalance. Given the sheer numbers of games in a major-league campaign, the effect of scheduling ultimately isn’t a major difference-maker. Talent and luck have much more influence over a club’s win-loss record. In any given month, however, scheduling imbalances can become much more pronounced.

Consider this: at the beginning of the season, just one team featured a projected gain or loss as large as three wins due to scheduling. The Texas Rangers were expected to lose three more games than their talent would otherwise dictate. Right now, however, there are eight teams with bigger prorated schedule swings than the one the Rangers saw at the beginning of the season — and those swings could have a big impact on the remaining pennant races.

To provide some backdrop, the chart below ranks the league’s schedules, toughest to easiest, compared to an even .500 schedule.

The Diamondbacks have a pretty rough go of it. Outside of five games against the Padres, the other “worst” team they play is the San Francisco Giants. They have one series each against the division-leading Astros, Braves, and Cubs along with a pair of series against both the Dodgers and Rockies. If Arizona were chasing these teams for the division or Wild Card, their schedule would present them with a good opportunity for making up ground. Given their current status, however, it just means a lot of tough games down the stretch.

Clay Buchholz has been rejuvenated in Arizona. Signed off the scrap heap in early May — the Royals had released him — the 34-year-old righty is 6-2 with a 2.47 ERA in 12 starts since joining the Diamondbacks. He twirled a complete-game gem on Thursday, holding the Padres to a lone run.

Health had been holding him back. Buchholz has battled numerous injury bugs over his career, particularly in recent seasons. Cast aside by the Red Sox after a tumultuous 2016 — a 4.78 ERA and a six-week banishment to the bullpen — he made just two appearances for the Phillies last year before landing on the disabled list and staying there for the duration. Frustration was clearly at the fore.

Truth be told, he’d rarely been his old self since a sparkling 2013 that saw him go 12-1 with a 1.74 ERA — and even that season was interrupted by injury. Given his travails, one couldn’t have blamed him had he thrown up his hands and walked away from the game.

That wasn’t in his DNA.

“No, this is what I do,” Buchholz told me earlier this summer. “I wasn’t ready to give it up. And while this offseason I told myself I wasn’t going to go through the whole minor league deal again, I swallowed my pride and did that for a little bit. It was for the best, because it helped me get to where I’m at now. It feels good to be able to go out there and throw without anything going on, mentally or physically.”

Buchholz made five starts in the minors before being called up, and he did so with a glass-is-half-full attitude. Read the rest of this entry »

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In the twenty-first installment of this series, we’ll hear from three pitchers — Patrick Corbin, Zach Eflin, and Sonny Gray — on how they learned and/or developed a specific pitch.

Patrick Corbin (D-backs) on His Slider

“My slider. When I was really young, I asked my father how to throw a breaking ball, and he showed me this grip. It’s something I’ve stuck with throughout the minor leagues and the big leagues. It’s been my best pitch, and it’s kind of neat that my father showed me the grip.

“I can’t remember exactly when it was, but probably around 10 years old, maybe the first couple of times I played catch with my father. He always used to say he loved throwing it at the left-handed batter’s hip and having him freeze, only to have the ball break over the plate. That’s something I’ve always remembered and taken with me.

If you’re like me, you’ve been assuming the Dodgers would end up in first in the NL West for a while. Indeed, our playoff odds are still big fans, because it’s hard to overlook the track records of the various players around the Dodgers’ roster. If I had to make a prediction right now, I’d still settle on the Dodgers to be there at the end. Maybe that makes me smart. Maybe that makes me stubborn. Could be a little of both. I don’t like to be put on the spot.

But for however much talent the Dodgers possess, on August 16 we’re looking at the first-place Diamondbacks. The club’s been playing .500 baseball for a month and a half, yet still, they’re looming above the Dodgers and Rockies. When it comes to explaining why the Diamondbacks are where they are, credit has to go to good hitters like Paul Goldschmidt, David Peralta, and apparently Daniel Descalso. Credit also has to go to good pitchers like Patrick Corbin and Zack Greinke. And then there’s the helpful matter of so-called “cluster luck” — the Dodgers have a better run differential than the Diamondbacks do. No team reaches first place because of one reason alone.

Here, however, I’d like to shine some light on the Diamondbacks’ greatest strength. To this point I’d say it’s gone underappreciated, but I’ll show you the evidence in seven plots. The Diamondbacks have had an incredible defense.
