Two weeks ago, Eno Sarris wrote about how Alex Cobb’s split-change has gone missing. The Tampa Bay Rays righty had a very good one before undergoing Tommy John surgery in May of 2015, but the arduous road back extracted a heavy toll. The changeup is a feel pitch, and — cue up some Righteous Brothers blue-eyed soul — Cobb lost that loving feeling.

Fortunately for the 29-year-old hurler, it’s not gone, gone, gone. As a matter of fact, his relationship with his signature offering is already being rekindled. Cobb threw his split-change just 10 times in the game about which Eno wrote. In ensuing outings that number has climbed to 13, and most recently to 23.

I haven’t spoken to Cobb since he last pitched, but I did talk to him after he faced Boston on April 16. That was the game where he threw 13 split-changes, along with 36 curveballs and 44 fastballs. He wasn’t particularly pleased with his performance, but he was thinking positive thoughts. Rather than feeling forlorn, he was looking forward to an inevitable reunion with a pitch he holds dear to his heart.

———

Cobb on why his changeup went missing: “If I had that answer, it would be here. But I do have ideas. Going into Tommy John surgery, you hear that the overall feel of pitches comes back slowly, and the changeup is usually the last one to come back.

“It has nothing to do with [flexor-group muscles, as Eno theorized]. I feel completely normal. When people say ‘feel on a pitch’ — especially a changeup — it’s usually a mechanical thing. Feel isn’t what the ball feels like. It’s not a literal term. It’s the way your body feels, in rhythm, over the rubber. We’re talking about inches, even fractions of inches, of changes that impact the flight of the ball.

If you’re in the Washington D.C. metro area and aren’t otherwise occupied on Monday night, join me and a bunch of local scribes at the Howard Theatre for Pitch Talks DC.

We’ll spend a few hours talking Nationals baseball and baseball in general, and it should be a good time. You can purchase tickets for just $20, or $15 if you use the promo code “NATS”. Going to be tough to find a better deal in town.

Additionally, Kevin has five pairs of tickets he’s going to give away to FanGraphs readers, so if you’d like to attend but don’t have $15 to spare, you can fill out this form and hope to land a pair of complimentary tickets to the show.

I’m excited to see you all there, and look forward to hanging out on Monday night.

Below is an analysis of the prospects in the Oakland Athletics 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 the 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
Barreto was signed by Toronto for $1.45 million back in 2012 and then traded to Oakland — along with Kendall Graveman, Brett Lawrie, and Sean Nolin — in exchange for Josh Donaldson. Bay Area sports talk radio still discusses the deal with frequency and bile, and largely considers Barreto the last hope for salvaging it, though Graveman and his sinker appear to be breaking out this year.

Seemingly ever since humans gained sentience, we’ve been obsessed with the concept of flight. How powerful birds must have seemed to ancient man, able to free themselves from the constraints of the ground. Joyous was the starling, dancing and warbling through the air. Terrifying was the hawk, diving for a kill. To fly is to move in ways unimaginable for those trapped on the surface. We stared at the sky, the last frontier to be conquered, and dreamed. We told stories of magical heroes and gods who could fly. We sought any way possible to experience it, from the Dark Ages to Da Vinci and on.

By the time we came up with hot-air balloons and gliders and airplanes and helicopters so that we could join the birds in the sky, perhaps we lost a little bit of that wonder. Generations have now grown up with intercontinental flight as a simple fact of life. We still dream of joining the birds in the skies, of flying like Superman. But we no longer wonder if it’s possible. We know that we can fly with mechanical aid. But we’ll never truly join the birds. At least not for more than a few seconds.

It’s a small stroke of genius that the gods put Chris Coghlan on a team named after a bird. And indeed, last night’s Blue Jays came in St. Louis against the Cardinals, who are also named for birds. Teams named for birds play each other all the time, of course. The Jays play in the same division as the Orioles. Almost none of those games, if none at all, have featured a moment like this.

We can’t earnestly call what Coghlan accomplishes here flight. If anything, it’s falling with style. It’s a leap and a near-perfect handspring. It’s something out of a gymnastics exhibition, except Coghlan is wearing cleats and a helmet instead of a unitard. It’s the closest anyone’s come to real, honest-to-goodness flight on a baseball field since Ben Revere achieved liftoff in 2013.

Coghlan didn’t plan on springing over the head of Yadier Molina. Like the most satisfying superhero origin stories, he didn’t know he had the power inside of him. He jumped because instinct told him to, because years upon years of baseball conditioning told him to score that run. Humans are capable of great physical feats when fueled by adrenaline and instinct. They can lift cars, run faster than they ever have before. For a few precious seconds, they can fly. If they’re lucky, they can even stick the landing, like Coghlan did.

Hello! Yesterday I posted this. In that post, I briefly discussed five outrageously hot offensive starts — specifically, those achieved by Eric Thames, Bryce Harper, Eugenio Suarez, Mitch Haniger, and Aaron Judge. I solicited feedback in the form of a rest-of-season wRC+ projection for each bat. Although I didn’t include every hitter off to a scorching start, I touched on five of significant interest, and your overall participation level has been great. Thank you for that — without participants, these polls would be super embarrassing.

Comments and tweets were left suggesting I run a similar post, focusing on guys who’ve been bad hitters. This has happened because humans love symmetry, and also because it’s just simply the obvious thing to do. So now, same thing, with different players owning very different numbers. Again, the post below doesn’t cover everyone who’s mired in a slump — sorry for those of you who want to read about, say, Carlos Gonzalez or Keon Broxton or Jonathan Lucroy. I’ve chosen five players and stuck with five players, and I’d love it if you’d participate once more. There’s no such thing as a participation trophy, but if there were, you could get one! All for placing an internet vote. (Actually up to five internet votes.)

The Cincinnati Reds are young and rebuilding, so it’s not too much of a surprise that, this year, they’ve had more players make their major-league debuts than any other team. Yesterday, a pitcher named Ariel Hernandez showed up for the first time. He was tasked with some early innings in relief of an unsuccessful starter. Although it’s never easy to make one’s first-ever big-league pitches, some of the pressure is off when your team’s already losing 10-4.

Hernandez entered in the bottom of the fourth. In this post, I’d like to try something. He entered with one out. It took him six pitches to get out of the inning. Hernandez completed two more innings afterward, but I want to look at those six pitches alone. And here’s the idea: I want to estimate Hernandez’s projected ERA at each instant. That is, I want to take a stab at his rest-of-season ERA given only the information provided to me. I knew nothing about Hernandez before, and the same presumably goes for many of you. He’s working now to fill up a blank slate.

Here goes nothing! Six Ariel Hernandez pitches. His first six meaningful pitches, against major-league hitters.

To start, we might as well revisit the difference between command and control, or at least the accepted version of that difference: control is the ability to throw the ball into the strike zone, while command is the ability to throw the ball to a particular location. While we can easily measure the first by looking at strike-zone percentage, it’s also immediately apparent that the second skill is more interesting. A pitcher often wants to throw the ball outside of the zone, after all.

We’ve tried to put a number on command many different ways. I’m not sure we’ve succeeded, despite significant and interesting advances.

You could consider strikeout minus walk rate (K-BB%) an attempt, but it also captures way too much “stuff” to be a reliable command metric — a dominant pitch, thrown into the strike zone with no command, could still earn a lot of strikeouts and limit walks.

COMMANDf/x represented a valiant attempt towards solving this problem by tracking how far the catcher’s glove moved from the original target to the actual location at which it acquired the ball. But there were problems with that method of analysis. For one, the stat was never made public. Even if it were, however, catchers don’t all show the target the same way. Chris Iannetta, for example, told me once that his relaxation moment, between showing a target and then trying to frame the ball, was something he had to monitor to become a better framer. Watch him receive this low pitch: does it seem like we could reliably affix the word “target” to one of these moments, and then judge the pitch by how far the glove traveled after that moment?

How about all those times when the catcher is basically just indicating inside vs. outside, and it’s up to the pitcher to determine degree? What happens when the catcher pats the ground to tell him to throw it low, or exaggerates his high target? There are more than a few questions about an approach affixed to a piece of equipment, sometimes haphazardly used.

There’s something odd about the Cubs’ starting rotation, and I wrote about it last week. All five pitchers have been working with reduced velocity, relative to where they were last season. When it happens to one guy, it’s a potential problem. When it happens to five guys…I suppose it’s a potential *huge* problem, but it’s also a potentially deliberate pattern. I speculated as much, offering that the Cubs might be trying to back off their main arms since they’re coming off an extended season, and preparing for another.

Jake Arrieta has been okay, reduced velocity or not. The same goes for Jon Lester, who looks like the same pitcher. However, it’s a different story when it comes to Kyle Hendricks. Like the other starters, Hendricks isn’t throwing as hard as he used to. But then, Hendricks is sitting on a 6+ ERA. He specialized in command and soft contact. Now he has worse command, and he’s allowing hard contact. As far as Hendricks is concerned, something seems awry, although it looks to me to be mechanical.
