Right-hander Tyler Chatwood signed with the Cubs today for three years and around $40 million, according to Jon Morosi. The contract is about what one might expect. Dave Cameron, for example, called for Chatwood to receive $10 million a year for three years. The Cubs have given him more annually than Cameron expected. But for one of the youngest pitchers on the market, it’s not absurd.

But there’s also another reason for optimism regarding Chatwood’s near future besides just his relative youth. Given the tools at our disposal, there appears to be evidence that Chatwood’s stuff hasn’t fully translated into results.

As much as certain aspects of pitching remain a mystery when it comes to analytics, we’ve figured out a few things about the changeup. Like, movement is good! And like, a bigger velocity gap is good if you want whiffs! Those sorts of relationships can be identified pretty easily. And since movement and velocity become stable really quickly, you can cut this sort of thing into smaller samples and still get meaningful results.

You can ask things like: whose changeup improved the most in the second half, when it comes to things like velocity and movement differential off the fastball? And then you can get answers.

When Travis Sawchick asked you which question was most important on Shohei Ohtani’s questionnaire, you answered overwhelmingly that the team capable of keeping him healthy — or of convincing Ohtani that they’d keep him healthy — would win out. Travis went on to use a metric, Roster Resource’s “Roster Effect” rating, to get a sense of which team that might be. The Brewers, Cubs, Pirates, and Tigers performed best by that measure.

Of course, that’s just one way of answering the question. Health is a tough thing to nail down. To figure out which team is capable of keeping Ohtani the healthiest, it’s worth considering the possible implications of health in baseball. Roster Effect, for example, considers the quality of the player and seems to be asking: which rosters were affected the most by poor health? That’s one way of approaching it. Let’s try a few others and see who comes out on top.

In the midst of a slow beginning to the offseason, the big slugger in Miami keeps hitting homers — at least when it comes to providing content. Even after I made the case for acquiring Giancarlo Stanton — particularly for a team like the Giants — and Craig Edwards pointed out how an opt-out lowers Stanton’s value, the NL MVP remains a source of inspiration. Because, while all of those posts regarding Stanton feature assumptions about his ability to produce years from now, none of them focus on how well or poorly he’ll age, specifically. How he ages, though, is super important to how one thinks about his contract. It’s a matter worth unpacking further, in other words.

Not every team approaches the offseason looking to get better in the same way. That much is obvious: budget alone can dictate much of a club’s activity on the free-agent market. A little bit less obvious, though, is how the present quality of a team’s roster can affect the players they pursue. Teams that reside on a certain part of the win curve, for example, need that next win more than teams on other parts. That can inform a team’s decisions in the offseason.

There’s no player more polarizing this offseason than Miami outfielder Giancarlo Stanton. The Marlins’ new ownership group has indicated that they’d like to reduce the club’s payroll by as much as $50 million before the start of the 2018 campaign. With 10 years and $295 million remaining on his contract, Stanton is the logical place to begin with any such cuts.

The prospect of a Stanton trade isn’t particularly straightforward, though. There appears to be little consensus on the relative value of his production to the costs required to employ him. Is he overpriced and injury prone — should he be treated as a salary dump? Or is he the rare available peak-aged star who should be coveted?

What follows is a series of points in support of the latter case.

He’s not necessarily injury prone.
Much has been made of Stanton’s inability to put up 600-plus plate appearances — probably too much. It’s true that he’s only crossed that threshold four times over eight years in the bigs (yes, we can count the 636 he put up over two levels in his rookie season), but that’s not as damning as it may seem. And that’s not just because one of those four injury-shortened seasons came from a broken jaw on a hit by pitch — that is, by means of a one-time event, not a chronic problem.

Congratulations to Cody Bellinger for winning the National League Rookie of the Year Award! While I’m actually writing this post before the award is announced, the case for Bellinger is pretty clear — no National League rookie had a bat like his while playing in so many games. As a bonus, Bellinger also recorded strong numbers on the basepaths and became one of 12 first basemen to add four or more games in center field since free agency began in 1974. Using a swing that the Dodgers helped him build, he hit the third-most home runs in a rookie season, ever. Bellinger had a top-20 rookie season over that time span in the National League and deserves his award for regular-season excellence.

But, as a member of the Baseball Writers Association, I had the benefit and honor of fulling out a full ballot for this award, not just one name. It’s down the ballot where things got difficult. It’s down the ballot where I began to wonder how much the future matters when believing the past. It’s down the ballot where I hemmed and hawed, considering the qualities of players as differently excellent as Luis Castillo, Paul DeJong, and Rhys Hoskins.
