Below is an analysis of the prospects in the Arizona Diamondbacks farm system. Scouting reports are compiled with information provided by industry sources as well as from my own observations. The KATOH statistical projections, probable-outcome graphs, and (further down) Mahalanobis comps have been provided by Chris Mitchell. For more information on thes 20-80 scouting scale by which all of my prospect content is governed you can click here. For further explanation of the merits and drawbacks of Future Value, read this. -Eric Longenhagen

The KATOH projection system uses minor-league data and Baseball America prospect rankings to forecast future performance in the major leagues. For each player, KATOH produces a WAR forecast for his first six years in the major leagues. There are drawbacks to scouting the stat line, so take these projections with a grain of salt. Due to their purely objective nature, the projections here can be useful in identifying prospects who might be overlooked or overrated. Due to sample-size concerns, only players with at least 200 minor-league plate appearances or batters faced last season have received projections. -Chris Mitchell

Scouting Report
The Diamondbacks drafted Banda out of high school in 2011. He didn’t sign, though, and then matriculated to JUCO powerhouse San Jacinto in Houston. The Brewers drafted and signed him the next year and Banda spent two years struggling in Rookie-level ball before the Diamondbacks acquired him in the Gerardo Parra deal (along with Mitch Haniger) in July of 2014. Banda took off after that, went to the Futures Game this year and had success at Triple-A in the hitter-friendly environs of Reno.

Yesterday, the Diamondbacks introduced Mike Hazen as their new general manager and head of baseball operations, who is taking over for Dave Stewart after a two-year failed experiment in their front office. Hazen was most recently the GM in Boston, serving as Dave Dombrowski’s second-in-command, and has been an integral part of a Red Sox front office that built one of the best young cores in baseball. The Diamondbacks are hoping Hazen will lead them in that direction now, and allow them to build a sustainable winner in Arizona.

But before he can do that, Hazen and his staff will have to determine their course of action this winter, and whether the team is going to try and retool a roster that just lost 93 games or if he’s going to pivot away from the team’s attempt to contend in the short-term in favor of acquiring assets for the long-term. When asked about this at the press conference, Hazen demurred.

“I don’t have a defined view just yet,” Hazen said. “It would be irresponsible for me at this point to sort of say exactly how we’re going to attack the roster.

“We want to bring a championship to this city and state, but we also know that there’s going to be decisions that need to be made. We’ll have more concrete answers on that as we move through the offseason. We’ll see what the landscape is in the marketplace.”

That’s a nifty non-answer, but in reality, it’s also likely the correct one. It doesn’t really make sense to be committing to a certain path on your first day on the job, for one, but also, despite the dumpster fire that was the Diamondbacks 2016 season, it isn’t actually clear what the Diamondbacks should do this winter, and they probably do need to explore both paths.

Eric Longenhagen is publishing brief, informal notes from his looks at the prospects of the Arizona Fall League and, for the moment, the Fall Instructional League. Find all editions here.

As Fall Instructional League winds down here in Arizona, teams have begun playing their games earlier in the day, allowing scouts to double and triple up should they so choose, catching instrux at 9 or 10 am before moving on to the afternoon and night Fall League games. For me yesterday, that meant seeing the Brewers’ and Diamondbacks’ instructional-league teams in the early morning. Of note from that game, the Brewers lined up second-round pick Lucas Erceg at shortstop and shifted Gilbert Lara over to third. Lara’s destiny likely lies at a position other than his usual shortstop — and so, too, does Erceg’s (despite a 70-grade arm) — and this was probably more of a fun experiment or opportunity to let Lara move around than it is earnest developmental news for Erceg, who has looked great throughout instrux but can’t play shortstop.

Luis Alejandro Basabe homered the opposite way during the game. He has more power than his incredibly small frame would otherwise indicate. His double-play partner, Jasrado (Jazz) Chisholm, showed off his precocious defensive ability at shortstop, ranging to his left behind the bag, corralling an odd hop while he simultaneously made contact with second base and then making a strong, mostly accurate throw to first base from an awkward platform. It wasn’t especially pretty but an impressive play nonetheless.

Even if you didn’t predict great things for the Diamondbacks this year, it’s hard not to be disappointed by their 2016 season. You can set aside their various front-office nonsense and still come to that conclusion. Zack Greinke hasn’t been great, A.J. Pollock missed significant time, and Shelby Miller’s year has gone about as poorly as you could imagine. The club is set to lose nearly 100 games and finish last in the NL West.

You’d think that Jake Lamb offensive exploits would be among the club’s few points of pride this season. In 2015, Lamb recorded a 91 wRC+; he’s raised that figure to 115 this year. But it’s more likely that the club is worried about their young third baseman going into the season’s final games. After a scorching hot start, Lamb hasn’t just cooled off in the second half, he’s cratered.

We’ve all seen those swings so terrible that a batter can’t help but smile. Swings like this one from Brandon Phillips last year.

Phillips, of course, isn’t the only victim of this sort of thing. He’s been a league-average major-league hitter for a decade, which is a substantial accomplishment. But even accomplished hitters can look bad, can get it very wrong.

Were Phillips batting not for a last-place club but one contending for the postseason, we might gnash our teeth. Couldn’t he see that was a slider? What was he thinking? What was he looking at?

The answer to that last question, turns out, is way more complicated than it seems. Phillips clearly should have laid off a breaking ball that failed to reach the plate. He clearly has done that — otherwise, he wouldn’t have had a major-league career. So what happened? What did he see? Or not see? Ask hitters and experts that question, and the answers are vague, conflicting, and sometimes just strange.

I hadn’t planned on talking to Zack Greinke about the game he’d started the night before, but then, for the second time in his career and the first time since his rookie year, he went six innings and recorded only one strikeout. It was a win for the team, but maybe not his finest game, that one against the Giants on Tuesday night. So I had to say something. “They make a lot of contact,” he grumbled, “but it wasn’t ideal.”

When I asked him if anything was different, he shrugged. “Against guys like Denard Span, Ben Revere, Buster Posey, I’m not going to spend a lot of pitches going for the strikeout. They make too much contact.”

We’ve heard this sort of thing before, of course. Pitching to contact is even espoused as a general philosophy by some organizations. But it’s a little surprising to hear from this pitcher, who regularly strikes out 200 batters a year, even if he’s told us before that pitching to FIP — pitching to limit the walks and increase the strikeouts — just led to hard contact in the zone.

He also gave us a name! Denard Span, he of the 3.7% career swinging strike rate, good for 11th-best overall since he’s been in the league. Span, because of his contact-oriented skill st, has forced Greinke to approach him differently.

So let’s look at Greinke’s plan against Span this past Tuesday and see what he was trying to do.

Robbie Ray has a 7-11 win-loss record and a 4.31 ERA. Neither is impressive. Some of his other numbers are. The Arizona Diamondbacks left-hander has a 3.53 FIP and his walks and strikeouts per nine innings are 3.2 and 11.2, respectively. His velocity is also notable. Ray’s heater is averaging 93.9 mph and topping out at 97. Six weeks short of his 25th birthday, he’s never thrown harder.

There have been a few situational issues. Third time through the order has been the biggest problem — resulting in a .331/.373/.598 slash line — and he’s had trouble closing out innings. With two outs, opposing batters are hitting .286/.347/.432 against him. As August Fagerstrom wrote earlier in the month, despite his plus stuff, Ray is “something of an enigma.”

In his last start he was masterful. On Sunday, in San Diego, Ray allowed one hit — a home run by Patrick Kivlehan — and fanned 13 over seven innings of work. A week earlier, he sat down to discuss his repertoire and the reasons behind his not-without-flaws breakout.

———

Ray on his mechanics and velocity gain: “The velo on my fastball is up this year. I think a lot of that is just me understanding my body better and fine-tuning my mechanics to get maximum efficiency out of my body. It hasn’t been anything big. I did make a minor change with my initial step. I step back now, kind of at a 45-degree angle, whereas before I stepped a little horizontally.

Despite internally high hopes after some notable acquisitions over the winter, the Diamondbacks season has simply been an unmitigated disaster. As we head towards September, they have a 51-73 record, second-worst in the National League, and they’ve played every bit as poorly as their record indicates; they also have baseball’s second-worst run differential (-129) and third-worst BaseRuns expected run differential (-138). Basically every single thing that could have gone wrong did go wrong, and instead of becoming a contender, the team has fallen apart.

The lousy results might end up costing many of the high-ranking front office personnel their jobs. The team has yet to exercise their 2017 options on GM Dave Stewart or AGM De Jon Watson. Tony LaRussa’s contract also expires at the end of the year, and reports suggest that the team is considering another front office overhaul. Unsurprisingly, Stewart and LaRussa feel that they deserve more than just two years on the job and don’t think basing an evaluation of their job performance on the team’s 2016 record is fair.

“We had one good year, and if you look at what’s happened on the field this year, then one bad year,” Stewart said. “I think we deserve a tiebreaker.”

…

“I think our group has earned the benefit of the doubt,” La Russa told USA TODAY Sports, “but it’s their decision. The way I look at it, if you get an opportunity, you don’t complain about the length of the opportunity. So I don’t complain about that.

“This is a game based on results. There was good improvement in ’15, and in ’16, was the opposite of that. It’s disappointing. We’re all upset about it.

“If somebody in charge is upset enough, they’ll make a change.”

In a rare case of agreement, I’m actually with LaRussa and Stewart on the idea that they shouldn’t be fired simply because the team performed badly in 2016. The results of one season, whether positive or negative, don’t provide enough information about the quality of the decisions made, and especially not the quality of the decision makers.

But I think the Diamondbacks should clean house anyway.

A poor base-runner and fielder who strikes out a lot and also doesn’t walk much needs to have a batting average like Tony Gwynn — or otherwise hit for a ton of power — to be a worthwhile player. This is the plight of Yasmany Tomas. He doesn’t run well and plays poor defense at one of the less challenging positions. He strikes out in a quarter of his plate appearances while walking just once every 20 times up. Expecting a Tony Gwynn batting average is impossible, and, up until a few weeks ago, Tomas wasn’t bringing much power either. The entire package rendered him a replacement-level player at best.

With eight home runs in the last ten games, however — and 12 in the last 19 games — Tomas is providing a glimmer of hope that he will not be a $68.5-million bust since signing with Arizona Diamondbacks before last season.

In 2015, Tomas parlayed an elevated .354 BABIP into just a .273 average, due largely to the strikeouts. The lack of walks led to an on-base percentage of only .305 on the season. He didn’t bring much power either, recording only nine home runs and a .128 ISO. The final product: an 88 wRC+ and -1.3 (that’s negative 1.3) WAR. Tomas got off to a good early start last season by taking the ball the other way. Of course, doing so muted his best tool, which was — and remains — his raw power. Out of the 211 hitters last season who recorded at least 400 plate appearances, Tomas’ 31.7% pull rate was 192nd, just ahead of Alcides Escobar. Outside of great all-around hitters like Ryan Braun and Paul Goldschmidt, the hitters around that range consist mostly of speedy, slap-happy type hitters. Not the type of company Tomas would want to keep, in other words.

Compounding Tomas’ pull problems last season was his inability to get the ball in the air. Tomas’ 54.9% ground-ball rate was 12th highest in MLB last season, and his 23.2% fly-ball rate was 15th lowest. Again, those numbers are more common among slap hitters who lack Tomas’ raw power. His problems last season were evident in his spray chart, seen below.

Note, on the pull side, how there’s roughly one black dot (home run) for every two blue dots (fly balls in the outfield). If he could pull the ball in the air, there was a decent chance — again, with his raw power — that Tomas would be able to hit it out. But the changes were few and far between. Tomas recorded a total of 297 batted balls last season but pulled just 94 of them (31.6%). Of those, only 17 (18.1%) were fly balls. Twenty-four percent of his pulled fly balls left the park, but because he gave himself so few opportunities, his power numbers were weak.
