This past Sunday’s notes column led with Scott Radinsky’s evolution as a pitching coach. Admittedly old-school when he first started out, the former big-league left-hander has since incorporated a heavy dose of new-age into his approach. TrackMan and the Angels’ analytics team were his allies as he served as Anaheim’s bullpen coach each of the past three seasons.

Today we’ll hear from Radinsky on several of the team’s relievers going forward. He won’t be with them — along with a few other Angels coaches, he won’t be returning — but he certainly knows each of them well. Having been hands-on with their development — particularly the youngsters of the bunch — he sees plenty of blue skies ahead for the club’s bullpen.

Radinsky on Hansel Robles: “Sometimes it takes awhile for a guy to buy in to what we’re sharing with them, but once he does, he can make real strides. It’s not the Bible, but it is well-thought-out information. This isn’t like back in the day when a pitching coach was on his own island and relying on the naked eye. It’s valuable data that is given to us as coaches, and it’s our job to translate it and pass it along to the players. We can use it to make them better.

“We had guys come [to the Angels] and buy in. They would realize, ‘Damn, man.’ Hansel Robles, from the Mets. This guy was headstrong about using his fastball. His fastball is a great pitch — he can really backspin it at the top of the zone — but our encouragement was, ‘When the catcher puts down slider, you don’t always have to shake. Utilize the thing.’ And do you know what? The more he used it, the better it got. Not only that, the more respect his fastball got. The next thing you know, he became more of a complete pitcher, and we were able to use him in higher-leverage situations.

One of the worst called balls of the season was thrown, and called, in the seventh inning of a White Sox game on September 10. I always just measure these things by the distance from the center of the strike zone. Lucas Giolito threw a two-strike pitch close to the center of the strike zone. It was taken, and called a ball. I’m only bringing this to your attention because of the subsequent call on the Royals TV broadcast:

Steve Physioc: Right down the middle for ball three.
Rex Hudler: [laughing] Wowwwwww. Woo! We got away with one there.

Physioc and Hudler were *on it.* They talked through a slow-motion replay and everything. And, I mean, the call was clearly absurd. It merited some attention. But we’re talking about a mid-September game between the White Sox and the Royals. At the end of the day, who cares, right? Still, the announcers were sufficiently locked in. Just four days later, we saw the true worst called ball of the season. It happened in the seventh inning of a game between the playoff-hopeful Dodgers and the playoff-hopeful Cardinals. As usual, a pitch sailed right down the middle, and it wasn’t called as a strike. It obviously should’ve been a strike. But no one said a word about it. Not on either side, not on TV or radio. It was as if the call didn’t happen at all. The worst such call of an entire baseball season.

That makes it sound ridiculous. Ridiculously negligent, on the part of everyone involved. In reality, there was a good reason. There’s usually a good reason. What happened is that Dakota Hudson threw a slider, right down the middle, and it was called a first-pitch ball. It was also maybe the least interesting part of the entire sequence.

One would think that setting a 15-year record for wins would feel more satisfying than it ultimately did for the 2018 edition of the Mariners. Alas, the world is as cruel as the Wheel of Fortune suggests: consonants are free but you have to pay for vowels. The A’s finished ahead of the M’s, giving the former club a place in the Wild Card Game.

The Setup

One of the defining features of the Seattle Mariners during the Jerry Dipoto regime is that the payroll has increased — from among the bottom 10 in 2012-13 to the back of the top 10 in 2018 — even though the club hasn’t been particularly active in free agency or signing young talent to long-term extensions.

Nearly eight months ago, I asked you to predict the future. Here are the words I used to introduce that piece:

In 2017, the fastball rate fell again. It’s been falling for some time now, but in 2017 it fell again, from 56.7% in 2016 to 55.6% last year. There’s some reason to think that the drop in the fastball rate is linked to the increase in baseball’s increasing swinging-strike rate, which in turn is linked to the rise in strikeouts and hit batsmen, and on and on and on. Baseball is a complex system of action and reaction, and small changes can grow large quickly.

So this year, I want to know: what do you think will happen to some of baseball’s key stats, league-wide, in 2018? Maybe you think home-run rates will go up and strikeouts will fall. Maybe you think if home-run rates go up then strikeout rates have to fall. Maybe you think it’s the other way around. I don’t know. But I want to hear from you, and most of all I want to hear why you think certain changes are linked, and others aren’t.

Below are a series of tables featuring 10 years’ worth of data for a few key metrics. I’ve also included percentage changes year over year. Below each table is a poll which asks you to indicate whether you think a given statistic will increase or decrease — and, if so, by how much. Answer each poll, if you wish, and then also indicate in the comments why you voted the way you did on one statistic and not others. In a year or so, I’ll come back to this and we’ll talk about it as a group. Maybe it’ll be interesting. Maybe it won’t! We’ll see.

A lot has happened since I wrote those words: I’ve gotten married, my wife and I moved from Boston to Seattle, and I became a telecommuter (in my day job; this one has always been virtual-only). Oh, and the 2018 season came and went. The future I asked you to predict is now a part of the history books. Let’s see how good you were at reading ahead.

Note: a reader of the March post suggested he/she was unsure if answers should be submitted in percent or percentage point. It’s possible, as a result, that a few ballots could distort the overall results. Because I presented all the original deltas in the form of a percent, however, that is how I have once again presented them here. Fortunately, none of this matters at all!

Usually these posts follow some kind of narrative structure. You wouldn’t necessarily say you come to FanGraphs for the storytelling, but any decent article is supposed to tell a story, even if it’s mostly statistical. I’m not going to bother this time. I’m not going to lead in with some manner of gripping anecdote. I just want to show you all a bunch of postseason numbers. I want to show them to you, because some of them are interesting, and postseason numbers aren’t always the easiest things to track down. Certainly not if you want to compare them to the same year’s regular-season numbers. That’s why I’m here today.

I’ve shown some of these plots in the past. What’s different now is that I have a few more plots, and also that the 2018 postseason is officially complete. Below, eight images, and limited commentary. How has playoff baseball compared to regular-season baseball over the years? I’ve gathered a whole host of statistical indicators, mostly with the help of Baseball Reference. Join me, if you will, on a quick analytical journey. We always guess at how the playoffs might play out, or which trends we might observe. We don’t have to guess about what’s already in the books.

Ben Lindbergh and Jeff Sullivan banter about Boston’s outfield rotation during the World Series, the significance of declining World Series ratings, the Orioles and the difficulty of classifying “tanking” teams, Manny Machado’s public persona and whether his reputation will hurt his free-agent appeal, and the Mets’ hiring of agent Brodie Van Wagenen as their new GM. They also answer two listener emails about the Astros and do a Stat Blast about the differences between postseason and regular-season baseball.
