Jeff, I think there is an imposter Matt in this chat.

There are too many Matts

Marcell Ozuna breakout year. It's happening
Jeff Sullivan

I mean, it probably isn't, but I appreciate your enthusiasm

David Robertson had issues with walks last year. How large of a sample do I need to know that he's overcome that issue? (no BB in 3 IP, but I suspect the answer is more than 3.)
Jeff Sullivan
10:23
Three months
10:24
Of some note: in a very small sample, Robertson has thrown 51% curveballs. He used to throw about 30% curveballs. Something to watch!

In the wOBA constants, why is a HBP worth more than a BB. I’d think they’d be essentially the same, but if anything, HBP would be worth less since it is a dead ball, negating a possible steal of 3rd or WP.
Jeff Sullivan
10:25
Walks are more likely to happen in situations where walks are less damaging. Like, there's an open base. HBPs are more random, and don't occur so often when there's an open base

Puig is at 52% GB. So... not really in the fly ball revolution?
Jeff Sullivan
10:26
Puig's average launch angle has dropped from 2015 to 2016 to 2017
10:27
But of course, this year's sample is tiny, and the intention is still there. We know what Puig is *trying* to do. That simply doesn't mean he can do it
10:28
The more important things to watch are his discipline numbers, but so far there hasn't been much. Will be better to check in after a month and a half

Do you think the Phillies call up JP Crawford at the end of the month?
Jeff Sullivan
10:28
So far he's 3-for-28 with 10 strikeouts
He's not earning anything

at what point does z-swing% stabilize to career norms? I'm looking at Longoria's numbers and he's over 10% below career average right now. at what point should I be hitting the panic button? I know it's still early but...
Jeff Sullivan
10:31
Right now, the difference between Longoria's Z-Contact% and his career Z-Contact% is about five or six whiffs
It's even less dramatic by the PITCHf/x numbers
10:32
Don't worry so soon

I live in Surakarta, Indonesia (now visiting my folks in Chicago), in between two of the largest volcanos in the world. I figure it's providence that I stumbled on one of your articles and became a regular reader while there.
Jeff Sullivan
10:32
Indonesian volcanoes are fantastic, provided you don't live within like five miles of them
Then they're a lot less fantastic
for you

This is the first time, in a long time, I haven't seen Mitch Haniger among players most searched on the site.
Jeff Sullivan
10:33
Everyone already takes him for granted as the best hitter in the game

When you say AJ Pollock is underrated do you mean you would take the over on his steamer/zips projections? What do you mean by he is underrated?
Jeff Sullivan
10:33
What does anyone mean by underrated?
There's no actual measure for it. It's a gut feeling. Like, does the average baseball fan get how good AJ Pollock is? I think no

Are you worried about Kershaw's slider?
Jeff Sullivan
10:35
In general, there is no pitcher I would worry about less
10:36
I mean, I don't know if Kershaw has something going on, but there's zero reason to believe he's throwing his pitches differently
And it just so happens we have new tracking technology this season, spitting out new information
It would take a *lot* for me to feel genuine Kershaw concern

Which poopy team turns out to be not-so-poopy?

Are you a better hitter than Byron Buxton?
