Pretty often, we get accused of overvaluing young players and prospects. The line of thinking is that we don’t properly appreciate the chances of a player flaming out and failing to accomplish anything of consequence. Yet, I don’t think we’ve ever been accused of overvaluing Kris Bryant. Around Bryant, there’s developed a consensus. Kiley ranked him first among Cubs prospects, obviously. Keith Law ranked him first in baseball. ZiPS is in love with Bryant, projecting a .364 wOBA. And Steamer, too, projects a .364 wOBA, exceeding its projections for Adrian Beltre and Robinson Cano. The No. 1 ZiPS comp is Evan Longoria. Bryant has yet to play in the major leagues, but already he’s considered a huge reason why the 2015 Cubs ought to contend for a playoff spot. He probably won’t be on the team out of camp, but he should be locked in before Memorial Day.

What I don’t intend to do is try to convince you that Bryant is going to bust. I don’t think Bryant is going to bust. He is uncommonly good, and uncommonly powerful, with power to all fields that comes out of a shorter swing than you’d expect. Yet there is one thing about Bryant worth considering as hype continues to build. He’s not a perfect prospect; there’s no such thing as a perfect prospect. Every prospect has a flaw, and Bryant’s is enough to raise the eyebrows. Think of it this way: if Bryant were to disappoint, why might that be? It seems we could already have a sign.

Remember when you thought baseball statistics were easy? Now, analytically, a statistic is hardly worth anything if it’s left unadjusted. You know all the adjustments that go into numbers. Adjustments for ballpark environment. Adjustments for era. Sometimes adjustments for league. As far as WAR is concerned, there are adjustments for position. There’s one adjustment we still don’t make, though: that’s adjustment for quality of opposition. In theory, if there were a pitcher who only ever faced the best teams, and a pitcher who only ever faced the worst teams, that wouldn’t be accounted for. That’s something you’d have to figure out yourself.

Related to this, James Shields has obvious selling points: first and foremost, he’s been good. He’s been durable, and he’s experienced, and he’s pitched in the playoffs, and everything. Then there’s one other thing I don’t think has gotten much attention: Shields has, relative to the average, faced a fairly tough slate of opponents. In the past, I’ve manually calculated average opponent wRC+. Baseball Prospectus has its own version, oppRPA+, and the big advantage of oppRPA+ is it’s already been calculated for me. The average, as usual, is 100. Last year, Shields’ opponents came in at 105. The year before that, 105. The year before that, 105.

Seems like this should be a good thing for Shields’ market; seems like, if you adjust for this, Shields’ numbers would get a boost. But how much does this matter, really? Coming up soon, a first attempt at an answer.

Now that football’s officially over for a while, countless sports fans are going to look ahead to the baseball season, with 2015 promising to be The Year Of Mookie Betts. This comes on the heels of 2014, which at one time promised to be The Year Of Billy Hamilton. And, to be fair, it was in a sense The Half-Year Of Billy Hamilton, but then Hamilton fell on harder times, losing a Rookie-of-the-Year race he once had all but locked up. Hamilton is now presumably older and presumably wiser, and he remains a player of unusual intrigue, along with being an important player for a Reds team that steadfastly refuses to tear down and start over.

Hamilton, naturally, has things to improve on. Every player in baseball has things to improve on — Clayton Kershaw has things to improve on — but Hamilton’s things are bigger than Kershaw’s things. Kershaw, for example, might want to polish his changeup a little more. Or maybe not. It’ll cross his mind. Hamilton, meanwhile, wants to not suck at hitting. His own manager has some ideas.

This is all the excuse I need:

#Rockies sign SS Omar Quintanilla, a utility INF for 2005-09 teams, and re-sign veteran RH reliever Rafael Betancourt

— Matt Eddy (@MattEddyBA) January 30, 2015

I’ve developed a very minor obsession with Rafael Betancourt. If you’ve paid close attention over the years, you might’ve noticed, but I wouldn’t blame you for not paying close attention whenever I write about Rafael Betancourt. But here I am doing it again, because I don’t think I’ve talked about this for more than two years, and each time I do it, I have a little more data. Do you like fun facts? Betancourt comes with a couple awesome fun facts. They’re almost totally irrelevant, in the grand scheme of things, but then, what isn’t?

Last week, people talked a lot about shifts. People talked about shifts because baseball’s new commissioner talked about shifts, and baseball’s new commissioner talked about shifts because shifts are up and runs are down. Now, it’s been mostly demonstrated that shifts are far from the main reason why run scoring is on the decline, but we all can at least agree that shift usage has skyrocketed. Last year there were almost six times as many shifts employed as there were in 2011. That’s a huge increase in not very much time. Seeing arrangements like this is becoming more common, and these days it’s a surprise when a pull-hitting slugger doesn’t face an adjusted infield.

With shifts on the rise as a defensive strategy, we’ve tried to figure out ways to counter the strategy with a different one at the plate. Ben Lindbergh wrote an excellent recurring column at Baseball Prospectus, detailing bunts against the shift. That’s the obvious bit — it seems almost too easy to get a free single when the third baseman is hugging second. Somewhat famously, bunts against the shift remain unusual. But there’s also the matter of hitting the other way. If a batter starts to spray the ball more, it could effectively undo the shift, and some players have talked about emphasizing an all-fields approach. So, out of curiosity, have we seen any progress? Have hitters demonstrated a better ability to go the other way?

Understand that I’m not a pitching coach. I’ve never played one on TV, and if I were asked to serve as one for an actual team, I’d be wildly out of my element. Pitching is complicated, and pitchers in the major leagues are impossibly good, and pitchers in the major leagues also have reasons for doing what they do however they do it. I don’t know if what follows is good advice for Kevin Gausman and James Paxton, or garbage. It’s just, there’s at least enough here that we can have a conversation.

Thursday, I wrote about the Rays and collecting and encouraging high fastballs. I’m interested in this high-fastball thing — it’s an intuitively sensible way to attack hitters who are increasingly prepared to hit down low. The Rays have talked about this idea. The Astros have talked about this idea. Brandon McCarthy has talked about this idea, during an interview for the Hardball Times Annual. It’s a trend, seemingly, to counter a different trend. But it’s worth noting, not just any fastball should be thrown high. You need to have some command, and you need to be able to generate the right kind of spin. You want to have a fastball — a four-seamer — with a high PITCHf/x vertical-movement reading. That’s not the way pitchers themselves think about it, but that’s how we can understand it.

Starling Marte was already one of the kings of hidden value. Metrics like Wins Above Replacement (WAR) have loved him, despite his average power, and despite his ugly ratios of strikeouts to walks. One contributing factor has been that he’s played half the time in an extremely pitcher-friendly ballpark, but this goes well beyond that. Marte has done a little bit of everything.

Forcing mistakes? Last season, Marte reached base 14 times on defensive errors. No one else in baseball exceeded 12. It’s an open question as to whether forcing errors is any kind of sustainable skill, but it makes sense that Marte puts pressure on the defense with his speed. Right there, you’ve got 14 outs that turned into non-outs. That’s one example of hidden value.

And while Marte has drawn just 66 walks as a big-leaguer, he’s also reached base another 44 times on hit-by-pitches. No one wants to be hit by a pitch, and Marte has been hurt by getting drilled, but reaching base is valuable, and Marte has this additional means. Over the last two years, Marte is the league leader.

Then there’s the matter of baserunning. Marte’s been caught stealing a whole bunch of times, but he’s also been successful a whole bunch of other times, and baserunning is about more than just stealing anyhow. It’s also about awareness, about being able to take extra bases when opportunities present themselves, and overall, the last two years, Marte has been worth about 13 runs more than average with his legs. That ranks him sixth, between Elvis Andrus and Mike Trout.

Of course, there’s also the defense. Marte is a corner outfielder who’s good enough to be a center fielder. By one metric — UZR — Marte has been worth almost 20 runs more than the average left fielder. By Defensive Runs Saved, he comes in at double that. Nobody questions that Marte is an outstanding defender, covering a lot of ground in what’s a relatively expansive section of the PNC outfield.

With everything he’s done, Marte has demonstrated that he’s a quality player, and a definite building block. He’s been one of the better players in the National League, and he’s been a huge reason behind the Pirates’ return to relevance. All that’s been missing have been a few developments within the box. Except, perhaps, those developments might’ve already taken place.

A couple weeks ago, the Rays signed Everett Teaford to a minor-league contract. Even if you noticed it, you forgot it, because people tend to forget all these minor-league acquisitions, and if you remember Teaford for anything, it’s not for being good. After being not good for the Royals, Teaford spent last year in Korea, where he had a league-average ERA. I don’t know if he changed something; I don’t know if the Rays saw something. But I know I can look at Teaford’s PITCHf/x page on Brooks Baseball, and he’s flashed something of a live heater. The vertical-movement column shows a pitch’s movement relative to a pitch thrown with no spin. The league-average four-seamer comes in just shy of 9 inches. Teaford’s been a little north of 10. That’s where you start talking about rise.

And when you talk about rising fastballs, you’re talking about something of great interest to Tampa Bay. They don’t actually rise, of course — they just don’t sink as much as normal fastballs. And while Teaford might not throw a single pitch for the Rays in the regular season, his fastball, at least, looks like it could fit in. The Rays have something going on, and while they’re not the only team with the idea, they seem like the most aggressive in the implementation.

Have I mentioned lately how helpful the chats can be when it comes to finding things to write about? You guys don’t know how valuable you are. Dozens upon dozens of questions, if not hundreds upon hundreds, and out of those questions, longer posts can occasionally germinate. This is one of them! Because I’ve noticed a recurring kind of question about Drew Hutchison, and how much he might be capable of in 2015.

Pulling an example, from earlier January:

Comment From BJ Birdie
Drew Hutchison had a 26% k rate and 7% walk rate in second half of 2014 after changing his slider (slower, more vertical movement), what do you think his chances of a major break out are in 2015?

Dave Cameron: I think the research has shown that trying to use second half performance to predict future breakouts is a fool’s errand.

Dave’s right, of course. The smart thing to do is to always bet against a breakout, as foretold by an encouraging second half. But that’s also boring, and one figures encouraging second halves can sometimes mean something for the season to come. We’re all just here to analyze, right? So, let’s do some analysis. What on earth was the deal with Drew Hutchison’s slider?
