No, we aren’t just going to do a leaderboard sort for best movement in each direction and call it a day. It’s a little bit more complicated to figure out the best changeups by shape and speed, mostly because it’s all relative. The changeup, as the name implies, functions off of the fastball, as a change of pace and movement. So we need to define anything the changeup does relative to the pitcher’s fastball.

Then we can do a sort and call it a day.

In order to define fastball movement, let’s just group together all of the fastballs thrown by a pitcher. It’s probably more nuanced than that; the concept of tunneling or sequencing shows that pitchers can pair their changeup with one fastball or the other for different results. But some of this comes out in the wash: by averaging movement across fastballs, their selection of different fastballs will weight the movement in the direction of the pitcher’s usage.

So then our x and y movement, and velocity, are defined against this average fastball for each pitcher. Using a minimum of 50 changeups thrown, and z-scores to sum up the values, we can get a list of best changeups quickly.

First, the relievers.

The worst called ball of the season was literally a fastball in the middle of the strike zone. That makes it genuinely the worst called ball imaginable, with the consolation being that it at least didn’t matter very much. When I’ve written these posts in the past, I’ve noted that the bad called balls look worse than the bad called strikes. There is no called-strike equivalent of a ball on a pitch down the middle. You’ll never see a called strike on a pitch at the eyes. You’ll never see a called strike on a pitch in the dirt. I think the default is to call a ball, unless the pitch does enough convincing, and there are limits to that. Still, one post has to be followed by the other. Writing about the worst called ball means I have to write about the worst called strike. That’s below, and I’m sorry it isn’t more visually hilarious, but this is still the worst of something, over seven months of baseball, and the devil is in the details. The devil loves details.

The second-worst called strike of the season? I’ve already written that up, because it was the worst called strike of the season’s first half. It was a lefty strike, thrown by Max Scherzer to Odubel Herrera to open a ballgame. The pitch measured 11 inches away from the nearest part of the strike zone.

Unsurprisingly, the worst called strike of the whole season is similar, in that it’s a lefty strike away off the plate. Over time, we’ve grown kind of used to the lefty strikes getting called, but the thing about this is lefty strikes are balls. The zone shouldn’t extend off the plate in either direction, for anyone, but it has and it does, and hitters have to live with that. The second-worst called strike was 11 inches away from the zone. The worst called strike was 12 inches away from the zone. That’s 9% worse. Pretty big gap when you’re at an extreme.

The good news is nobody cared.

On Monday night, the Biloxi Shuckers, the Brewers Double-A affiliate, fell to Chattanooga in the Southern League championship. Following the loss, the Brewers rewarded several members of the Biloxi squad with promotions to the big leagues. Among Tuesday’s call-ups were: outfielder Michael Reed, infielder Yadiel Rivera, and right-handed pitchers Yhonathan Barrios, Adrian Houser, Jorge Lopez and Tyler Wagner. Let’s have a look at what the data have to say about these prospects. (Note: WAR figures represent projected WAR totals through age-28 season, according to KATOH system.)

Michael Reed, 4.5 WAR

Michael Reed opened the year with Double-A Biloxi, and was promoted to Triple-A on August 1st. He was later reassigned to Double-A for the playoffs to get a few more reps. All told, the 22-year-old hit a respectable .270/.377/.408 on the year with an impressive 27 stolen bases.

Two seasons ago, I ranked the job security of each general manager and listed GM prospects. I think I did a pretty good job with both lists given what we knew at the time, and may do it again as Opening Day 2016 closes in. We’ve had less executive movement in the last few off-seasons than usual and it looks like the regression is happening this year, with four GM jobs currently open and a likely fifth coming soon. This seemed like a good time to cover each of the situations in flux and target some possible changes in the near future, along with some names to keep in mind as candidates to fill these openings.

The Open GM Spots
We have two teams without a top baseball decision-making executive, in Seattle and Milwaukee:

Mariners
The Mariners moved on from (now former) GM Jack Zduriencik recently, a long-rumored move that club president Kevin Mather admitted he waited too long to execute. Mather has said they’re looking for a replacement sooner than later (likely eliminating execs from playoff teams), with GM experience (eliminating most of the GM prospects you’ll see below), and that the team doesn’t require a rebuild (meaning a shorter leash and higher expectations from day one). This should prove to narrow the pool of candidates a good bit, but this is still seen as the best of the currently open jobs.

Every year, a number of starting pitchers seemingly come out of nowhere to become significant contributors at the major-league level. Sometimes, as in the case of, say, Jacob deGrom, the sudden evolution at the major-league level is real and sustainable. In the case of the majority of these short-term success stories, the league adjusts, the pitcher is unable to, and either disappears from the major-league scene or settles into a lesser role.

Coming into the 2015 season, Brewers right-hander Taylor Jungmann appeared to be little more than a failed first-round pick, with prospects of perhaps a big-league cup of coffee in his future. Instead, he has turned out to be a bright spot in a lost season for the Brew Crew since being summoned to Milwaukee in early June. Has the big righty turned a corner, settling in for a long run in the big club’s rotation? Or is this a short-term mirage, a dream that the big righty might wake up from any moment now?

When faced with batters on base, Milwaukee Brewers righty Taylor Jungmann goes to his sinker more and throws lower in the zone. He hasn’t given up a home run on the sinker, and the pitch produces ground balls nearly three-quarters of the time. So why doesn’t Jungmann go to the sinker more often?

“What makes the sinker better is that I don’t throw it as much,” Jungmann told me before a game against San Francisco. “It makes it that much more effective because they aren’t looking for it. If I threw it every single pitch, my four-seamer would be better.”

Right now, Jungmann has found the right uses for his sinker. If he used it more, he’d get less value from each additional sinker. This is what makes evaluating pitches by their peripherals so difficult, especially in small samples. Sure, Mat Latos has gotten six whiffs on 24 changeups this year — for a percentage that’s almost twice the average changeup whiff rate — but that doesn’t make the pitch good.

Milwaukee Brewers prospect David Denson made history yesterday when he revealed he is gay. With his announcement, Denson became the first active, openly gay player in the history of affiliated baseball.

Given his significance to the game, there’s unlikely to be any shortage of coverage regarding Denson in either the near- or long-term. As some of the authors of that coverage have already noted, attempting to become a major leaguer is difficult enough without having to contend with questions of personal identity and concerns about acceptance at the same time. Denson himself has stated that he’s relieved that he can divert more of his energy now to baseball itself.

What I’d like to do here is set aside for a moment the implications of David Denson, gay ballplayer, and to utilize my KATOH projection system to consider briefly Denson’s prospects for reaching the majors.

Just 19 now, Denson was drafted by the Brewers in the 15th round in 2013, and has split the 2015 season between Low-A Wisconsin and Rookie League Helena, where he currently plays. In 268 trips to the plate this year, the first baseman has hit just .229/.313/.360, due in no small part to his elevated 26% strikeout rate. Denson opened the year in Low-A, where he also spent the second half of the 2014 season. But the Brewers reassigned him to extended spring training in May when he was hitting .195/.264/.305. He’s put up a more respectable .247/.339/.390 line since joining the Brewers Rookie League affiliate in June. Based on his 2015 numbers,  forecasts Denson for just 0.2 WAR through age 28, with a meager 6% chance of cracking the big leagues.

Last week, in this space, I wrote about Dave Dombrowski’s Achilles Heel in the wake of the Tigers letting go of their long-tenured General Manager. Yesterday, another long-term General Manager was relieved of his duties, as the Brewers have moved Doug Melvin “into an advisory role”, opening up their GM position for the first time since 2002.

Like Dombrowski’s start in Detroit, Melvin’s first few years in Milwaukee were pretty rough. The team lost 94 games in both 2003 and 2004, then hung around .500 for the next three years, so it was five years of laying the groundwork for a competitive team. But in 2008, things started to come together around a strong young core that included 24-year-old sluggers Prince Fielder and Ryan Braun and 25-year-old middle infielders J.J. Hardy and Rickie Weeks. To supplement the team’s homegrown core of All-Star hitters, Melvin made a big mid-season trade for CC Sabathia, whose dominant performance helped carry them to the team’s first postseason berth since 1982.

While Sabathia was just a half-season rental — and predictably signed for big money in New York that winter — the Brewers retained the young core that looked like it should form the foundation of a perennial contender. However, since the start of the 2009 season until Melvin’s resignation, the team went just 540-545 and only made the postseason in one out of those seven years. While Dombrowski is leaving Detroit on the back of a long run of success that may just now be coming to an end, Melvin’s track record is more of a long string of unfulfilled potential.

So why weren’t the Brewers able to turn one of the best young groups of home-grown hitters into a consistent winner? Unlike with Dombrowski, Melvin didn’t have one glaring flaw that came back to haunt him on an annual basis. Instead, the Brewers lack of success can be chalked up to three significant organizational failures over the last seven years.

This breakdown starts with the Scott Kazmir deal on July 23, but there weren’t any trades from the 16th to the 23rd, so this covers the whole second half of the month, trade-wise, up until now. I count 25 total trades with prospects involved in that span that add together to have 58 prospects on the move. Check out the preseason Top 200 List for more details, but I’ve added the range that each Future Value (FV) group fell in last year’s Top 200 to give you an idea of where they will fall in this winter’s list. Also see the preseason team-specific lists to see where the lower-rated prospects may fall within their new organization.

40 FV is the lowest grade that shows up on these numbered team lists, with 35+ and 35 FV prospects mentioned in the “Others of Note” section, so I’ll give blurbs for the 40 FV or better prospects here. I’ve also linked to the post-trade prospect breakdown for the trades I was able to analyze individually, so click there for more information. Alternately, click on the player’s name to see his player page with all his prior articles listed if I didn’t write up his trade.

I opted to not numerically rank these players now, but I will once I’ve made the dozens and dozens of calls necessary this fall and winter to have that level of precision with this many players. Look for the individual team lists to start rolling out in the next month, with the 2016 Top 200 list coming in early 2016. Lastly, the players are not ranked within their tiers, so these aren’t clues for where they will fall on the Top 200.

Days after acquiring Scott Kazmir, the Astros went out and bought more players last night. This time around, they acquired Carlos Gomez and Mike Fiers in exchange for four prospects: Brett Phillips, Domingo Santana, Adrian Houser and Josh Hader. Let’s take a look at how this quartet of minor leaguers projects. (Note: WAR figures denote WAR through age-28 season.)

Brett Phillips, 3.7 WAR

Brett Phillips, 21, has split the 2015 season between High-A and Double-A where he’s hit .320/.377/.548 in 97 games. Phillips hit for gobs of power (.268 ISO) at the former location, but it’s yet to show up (.142 ISO) at the latter. Still, his ability to get on base has enabled him to post a 133 wRC+ since his promotion. Phillips also has above-average speed, which shows up in his stolen-base numbers.
