Credible baseball analysis, such as the sort which populates this website, is recognizable insofar as it begins with evidence and then works from that evidence towards a conclusion. The present document differs in this way from credible baseball analysis. For the purposes of this post, what the author has done is actually not to begin with evidence, but rather to start with the conclusion itself — and then worked to find evidence that might support that conclusion.

Here’s the conclusion, now and forever: Oakland minor-leaguer Max Schrock is a more promising baseball prospect than so-called “experts” would have everyone believe. Why it’s essential to reach this conclusion, that’s not entirely clear. The return on investment of this eventuality isn’t immediately evident. However, ever since the present author wagered his professional reputation on the suggestion that Schrock would someday become an MVP, any data which supports that unlikely hypothesis has held some interest for him. And so what one finds here is a post that supports that unlikely hypothesis.

This particular dispatch from the Max Schrock Propaganda Machine regards Schrock’s performance at the Arizona Fall League. As of today, the AFL has only a single game remaining on its schedule — namely, the championship contest between Surprise and Schrock’s Mesa squad on Saturday. In other words, the bulk of the data for this year’s edition of the Fall League has been recorded. And what that data suggests, if one can believe it, is that Max Schrock is a more promising baseball prospect than so-called “experts” would have everyone believe.

Let’s begin with a recent observation:

I can't see so good without my glasses, can someone tell me which batter has lowest strikeout rate in Fall League? pic.twitter.com/ooUo9FFkor

What one finds here is a leaderboard of the AFL’s top qualified batters by strikeout rate, current as of a few days ago. What one also finds is Oakland minor-leaguer Max Schrock at the top of that leaderboard.

On Friday, news broke that the Blue Jays signed Kendrys Morales for three years and $33 million. Morales is clearly a quality hitter, but he can’t really do anything else, so Dave thought it was a bit of an overpay. Okay! Keep that in mind.

On Saturday, the Mariners traded for Danny Valencia. Kendrys Morales is 33. Danny Valencia is 32. Valencia is projected for a salary of $5.3 million in his last year of arbitration. This past year, Valencia was a better hitter than Morales was. Over the past two years, Valencia has been the better hitter. Over the past three years, Valencia has been the better hitter. Over the past four years, Valencia has been the better hitter. The evidence would suggest that Valencia is at least as good as Morales at the plate, and Valencia isn’t limited to being a DH. He’s also a slightly better runner. It would seem to make him the better player, even though he’s going to cost so much less.

From the Blue Jays’ perspective, there’s some value in having Morales locked in for a while. They have a DH for the foreseeable future. And there’s another aspect to this — Valencia, in the past, has been somewhat polarizing. It’s not that all of his teammates have hated him, but some of his teammates have hated him, and Morales is an easier fit into a clubhouse. It’s not a coincidence that Valencia is so well-traveled. But the Mariners are betting on production, figuring that any other issues can be dealt with later, and as a part of betting on production, they’re betting on Valencia’s recent transformation. It used to be, Valencia was a platoon guy, who brutalized southpaws. A couple years ago, it looks like he figured things out.

Valencia has looked like an everyday player, and he’s going to be treated like an everyday player. Over the past two seasons, he’s been as good a hitter as Buster Posey, Kyle Seager, and Christian Yelich. The drawbacks are that Valencia won’t be a defensive plus at first base or in the corner outfield, but he certainly fits a hole on the roster, and his 2017 will be affordable.

It hasn’t been hard to see that the A’s were going to move Valencia somewhere. Because of his surplus value, he wasn’t acquired for free. For giving up Valencia, the A’s are receiving Paul Blackburn, a 22-year-old righty who’s not regarded as a top prospect. What Blackburn doesn’t do is miss a ton of bats. What he does do is keep the ball on the ground, and he’s kept his walk rates low. He feels a lot like another Kendall Graveman, a guy who could become an established major leaguer in a hurry. Graveman made just 11 combined starts between Double-A and Triple-A. Blackburn just spent a whole season in Double-A, but he gave up just eight homers. He could be depth as soon as next season, and the A’s are no strangers to needing extra starting pitching. Blackburn could help them in the future more than Valencia ever would.

So it’s a neat little exchange. Depending on how you interpret Valencia’s clubhouse concerns, he might be a genuinely underrated player. Blackburn, also, might be differently underrated, but the Mariners don’t have a lot of shiny prospects to sell. The Blue Jays, I’m sure, are happy to have Morales. Maybe they very much didn’t want Valencia back. It’s enough to make you wonder, though.

Over the coming weeks, Eric Longenhagen will publish brief, informal notes from his looks at the prospects of the Arizona Fall League and, until mid-October, Fall Instructional League.

Athletics OF Lazaro “Lazarito” Armenteros continues to take better at-bats than I anticipated and has an advanced feel for his strike zone. The power is as advertised, too, though he’s extremely vulnerable against breaking balls and is often so far out on his front foot against them that he can’t do anything but foul them off and live to see another pitch. He has a 40 arm, is a 50 runner and a left fielder for me going forward.

Also of note for Oakland yesterday in a Fall Instructional game against the Angels was RHP Abdiel Mendoza, who just turned 18 in September. Mendoza is extremely skinny but loose and quick-armed. His fastball sat in the upper 80s but I think there’s a good bit more coming and I like Mendoza’s athleticism. He’s purely a teenage lottery ticket but one I think who’s worth following.

For the Angels, INF Julio Garcia took the field at shortstop, which is notable because I hadn’t seen him play there for over a year. Garcia, a switch-hitter, came over from the DSL late last summer and looked tremendous at SS, but has spent this year playing a lot of 2B and 3B in deference to, in my opinion, inferior prospects — and also lost a significant amount of playing time to a facial injury. Scouts like the glove, body and bat speed but want to see a more measured approach to hitting, especially from the left side. The Angels’ middle infield is crowded at the lower levels, a group that includes 2016 draftee Nonie Williams, who posted an above-average run time for me yesterday.

Also of note for the Angels yesterday was the cage work of 2016 2nd rounder, OF Brandon Marsh. Marsh has not played in games since signing (neither in the AZL nor during instructional league) but showed above average raw power during a side session yesterday. The body should grow into even more pop. Mid-way through his session Marsh paused to take instruction from a coach behind the cage and immediately made an adjustment on his subsequent swings.

In last night’s Arizona Fall League game between Peoria and Salt River, Mariners OF Tyler O’Neill posted a plus run time for me yesterday and showed off his plus bat speed on several occasions but I thought his at-bats were a little overaggressive. Seattle LHP Luiz Gohara sat 95-97, touched 98 and flashed a plus slider in the mid-80s but struggled with command and, at age 20, is already carrying what looks like 240-plus pounds.

Padres utility prospect Josh VanMeter squared velocity several times and had three hits. Orioles LHP Tanner Scott was touching 99 but not getting as many swings and misses as you might expect from a 95-plus mph heater and his low-90s cutter/slider wasn’t all that effective, either.

My favorite part of my job is when players ask me questions. It’s difficult enough to come up with questions on a daily basis, so it’s great to get a free piece — and it’s even better when the question came from someone who plays the game every day. Once you make it to the Show, it’s all about staying in the Show, and that means making the most of your athletic talents. Strategy is often the key component to these questions.

When Athletics infielder Jed Lowrie came bounding across the Oakland clubhouse to me with his question earlier this year, he’d already decided to act on what he had perceived as an issue with his new/old home park. In the spring, he’d connected with his hitting coach, Darren Bush, in order to work on going the other way since he was leaving Houston’s friendly confines for Oakland’s cold. Because fly balls die in Oakland, and opposite-field fly balls are, by nature, less damaging than their pull counterparts, part of that new “oppo” approach was a heavier ground-ball profile. Mission accomplished.

But the reason behind Oakland’s fickle fly-ball play was still on his mind. “I think it’s Mount Davis,” he said back then. His theory was that the wall-like 10,000-seat expansion in center field — constructed in 1996 and nicknamed Mt. Davis in scorn after the Raiders’ late owner Al Davis — was responsible for suppressing fly ball distance in the Coliseum.

Answering his question turned out to be fairly difficult.

In light of Oakland right-hander Jharel Cotton’s minor-league success, his major-league success (which includes a 1.50 ERA over three starts) isn’t an entirely surprising development. More surprising, perhaps, is how he’s achieved that success — less by means of his celebrated changeup and more by means of his barely-ever-mentioned-once cut fastball.

Curious as to what might explain this development — and curious, generally, about what constitutes a successful cutter — I contacted pitch-type enthusiast and mostly tolerable colleague Eno Sarris. What follows is the product of our correspondence. The author’s questions appear in bold, Sarris’s in normally weighted typeface.

*****

Because I’m not the foremost expert on anything, Eno — except perhaps the length and breadth of my own personal weakness — I’m also not an expert on Jharel Cotton. That said, it’s probably also fair to say that I’ve followed him with some interest. He finished atop the Fringe Five leaderboard last year (tied with Matt Boyd and Sherman Johnson). He finished among the top 10 on that same arbitrarily calculated scoreboard this year, too.

We don’t talk much about Matt Holliday these days. It’s been awhile since he was one of the best players in baseball. Probably the last time you could have honestly made that claim was in 2014, when his 132 wRC+ was 28th-best in the game. However, with the news that Holliday has probably succumbed to his thumb injury for the rest of the season, I thought we would take a minute to talk about Holliday. Holliday can’t do most of the things he used to, but even after all this time can still hit.

Holliday has always had a special place in my heart because he got to Coors Field at the same time as I did. I started working for the Rockies in March of 2004, about a month before Holliday would make an unexpected major-league debut. He got the call when both Preston Wilson and Larry Walker came up lame in the first couple weeks of what would become (at the time) the bleakest moment in Rockies history. Technically, the team’s winning percentage had been worse in 1993, but in 1993 no one in the Rocky Mountain region had cared, because they had a major-league team for the first time.

That 2004 season was bad not just because of the team on the field, but because it was the year the team traded Larry Walker away — twice — getting far less in return the second time. The first time, when they tried to trade him to the Texas Rangers for Ian Kinsler, Walker had vetoed the deal. He was then sent to the Cardinals, which, in retrospect, was absolutely the right move for Walker, who would finally get to play in the World Series that fall. I’m pretty sure the Rockies would have rather had Kinsler than Chris Narveson, though. In any case, trading away Walker meant that any scant hopes the team would contend had totally and completely died. The “Todd (Helton) and the Toddlers” era had begun.

The most prominent “toddler” was Holliday. He would come along slowly, but he could always hit. As fate would have it, the season he put it all together coincided with Troy Tulowitzki‘s arrival and Todd Helton’s final good season, and the three helped lead the Rockies to their first and still only World Series berth. Holliday slugged .607 that season, and if that seems like a ridiculous number, it is. Coors Field might still be a hitting haven, but no Rockies player has slugged .600 since.

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.

On Monday, the Oakland Athletics promoted a couple of hitting prospects from Triple-A: Renato Nunez and Matt Olson. Both Nunez and Olson came off the bench on Monday to make their big-league debuts. With Billy Butler out of the picture, and Danny Valencia likely soon to follow, Nunez and Olson might see a decent chunk of playing time these next two weeks.

Olson’s numbers have trended in the wrong direction since his 37-homer season in the Cal League in 2014. He slashed .249/.388/.438 in Double-A last year and only managed to hit .235/.335/.422 in the PCL this year. Throughout his minor-league career, Olson has demonstrated good power and a willingness to draw walks. He’s also a 22-year-old with a 6-foot-5 frame, which suggests he may still have some untapped upside. But his underwhelming performance, defensive limitations and 24% strikeout rate don’t bode particularly well for his future in the show.

KATOH pegs Olson for 3.7 WAR over his first six seasons by the traditional method and 2.8 WAR by KATOH+, which integrates Baseball America’s rankings. To help you visualize what his KATOH projection entails, here is a probability density function showing KATOH+’s projected distribution of outcomes for Olson’s first six seasons in the major leagues.

To put some faces to Olson’s statistical profile, let’s generate some statistical comps for the newest Brewers prospect. I calculated a weighted Mahalanobis distance between Olson’s performance this year and every Double-A season since 1991 in which a first baseman or corner outfielder recorded at least 400 plate appearances. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. A lower “Mah Dist” reading indicates a closer comp.

When Kiley McDaniel wrote about the Athletics prospects before the 2015 season, Ryon Healy was just a “name to note” with “55 raw power that plays down in games.” After Healy produced a nice year at Double-A — albeit one without much power — Dan Farnsworth didn’t add much love, saying that he didn’t think Healy had the “swing path to keep driving balls.”

They weren’t alone. Baseball America made him Oakland’s 22nd- and 23rd-best prospect those two years, respectively. He didn’t make it into either of the team write-ups on Baseball Prospectus. Keith Law didn’t include him in his Oakland write-up going into this season.

Healy is 24, yes. He’s only had 184 plate appearances, sure. But he’s already shown more power than projections and prognosticators had in mind for him, and it’s probably not a fluke. He’s made a change we’ve heard about from many other major leaguers. He’s not using the same swing path that kept him off the top-prospect lists.

Oakland right-hander Jharel Cotton made his major-league debut on Wednesday. The results were positive: over 6.1 innings, Cotton conceded just a lone run on two hits — the product, that run, of a homer by the Angels’ C.J. Cron. The process, while entirely adequate, was also slightly less positive: over those 6.1 innings and against those same 22 batters, Cotton recorded just three strikeouts.

In a sense, this start was the opposite of the sort which have defined much of Cotton’s season in the Pacific Coast League this year. Despite producing the best strikeout- and walk-rate differential (K-BB%) among all 57 Triple-A qualifiers in 2016, Cotton also recorded a 4.31 ERA — which, it turns out, is only the 35th-best ERA at Triple-A and even pretty middling among just PCL starters, too. The home runs were a problem for Cotton. Sequencing was a problem for Cotton. Controlling the strike zone wasn’t.

Apart from the runs he allowed and the runs he might have been expected to allow — whatever the discrepancy there — Cotton exhibited one quality yesterday that he’s exhibited all of this season and all of last season and maybe always since he was just a small child. An excellent changeup, is what. Lead prospect analyst Eric Longenhagen, among others, has described it as a plus-plus pitch — and it’s the presence of that pitch that has largely been credited with allowing Cotton to experience such great success as a professional despite a rather diminutive frame.
