We have a number of great ERA estimators on this site. FIP, xFIP, SIERA: choose your favorite, because they all have a place in attempting to better describe outcomes closer to a pitcher’s true talent over a given timeframe. Maybe you’re lazy, or maybe you’re different, but it can also be nice to have a dead simple one — which is where K-BB% comes in. If a pitcher is striking guys out and limiting walks, that’s a fundamentally positive thing, and it turns out K-BB% is actually the best in-season predictor of future performance out of all the ERA estimators on the site (though it’s still not a great predictor, to be honest). Unless a pitcher possesses a signature batted-ball profile, K-BB% represents a nice, handy way of feeling a little better about a guy if his ERA hasn’t been quite up to expectations. Or, you know, feeling worse about a guy whose ERA has been lower than what his peripherals seem to say it should be.

Which brings us to the current K-BB% leaderboard. A casual perusal yields these top-five worst K-BB% rates among qualified starters in the major leagues:

Negative? Negative! These guys all have pretty middling strikeout rates, and the top few have some serious control problems. Just in case you were wondering, no one ran a negative K-BB% among qualified starters last season. It makes sense, given that it’s a hard thing to do while still being allowed to pitch a lot of meaningful innings in majo- league baseball games. But Ventura is currently doing it, and his ERA is “just” 4.62! And yet this next table, of Ventura’s current FIP and xFIP ranks among qualified starters, seems relevant, given his current standing with strikeouts and walks: Read the rest of this entry »

Due to a fractured thumb, the Royals will be without Mike Moustakas for at least the next few weeks. No doubt, Kansas City will miss their three-plus win, All-Star third baseman. But as is often the case in baseball, one man’s misfortune is another’s opportunity. In this instance, the beneficiary is Cheslor Cuthbert, whom the Royals recalled from the minors to replace Moustakas.

Unless you’re a Royals fan or a prospect connoisseur, you might have no idea who Cheslor Cuthbert is, but my nerdily-sorted spreadsheets really like the Nicaraguan infielder. Last year, he hit .277/.339/.429 as a 22-year-old in Triple-A. He also struck out in an encouragingly low 14% of his trips to the plate. He already looks like a Royal.

That performance, along with the fact that he plays primarily third base — a somewhat premium defensive position — landed Cuthbert at 74th on KATOH’s preseason top-100 list, placing him tops among Royals farmhands. That was before he opened this season by slashing .333/.402/.624 in 24 games. He was one of the very best hitters at Triple-A over the season’s first month, and was quite possibly the best prospect-age hitter in Triple-A.

I gave Royals’ right-hander Chris Young a bit of an incredulous look — “You’re throwing the slider a ton this year!” He shrugged. Sure. “It’s okay, you can throw it inside and out, and it’s been good. But it moves a little differently depending on where you throw it.”

Young then mimicked the release point when trying to throw a slider inside to a right-handed hitter, and then he showed where the release point might be when throwing it outside to a right-handed hitter. One was straight to the plate, and the other had more side-to-side finish to it.

If you’ve pitched competitively — or, at least, possess more experience than my own, which is limited to throwing a whiffle ball to my kid while he imitates Julio Franco — this may be old hat to you. But to me, it was surprising and also totally logical at the same time. I immediately wanted to know what this looked like.

Lorenzo Cain has had a rough go of it so far. That much we can say with absolute certainty. Cain’s coming off a seven-win season in which he finished second runner-up — behind Josh Donaldson and Mike Trout — for the American League MVP, and there was also that whole world championship thing. The Royals weren’t — and aren’t — a team built around stars, but if there was a star of last year’s champs, Cain was the guy. It was also something like his breakout season, and while Cain isn’t young at 30 years of age, he’s certainly not old enough that we entered the offseason wondering whether he could sustain most or all of that breakout. Cain was the de facto star, and there was little reason to believe he wouldn’t continue being the de facto star.

Through 20 games of Kansas City’s victory lap, he’s been anything but. The only number you really need to know for now is 64, which is Cain’s wRC+ in 83 plate appearances. It’s a bad number. We know that. The bigger questions are ones like, “Why is the bad bad?” and, “Is there any good in the bad?” and, “Am I being the best version of myself?” We probably won’t get to all of that, but we’re going to try.

Let’s start with a good thing!

A good thing: Lorenzo Cain is walking a bunch! That’s a good thing. Because walks are good, and he’s doing them a lot. It’s not like Cain has just totally lost control of the strike zone and is suddenly going all Josh Hamilton on everything. When Josh Hamilton started going all Josh Hamilton on everything, it was almost like a flip switched and his career was put on hold until further notice. There’s beating yourself, and there’s getting beat. Beat yourself and the opponent doesn’t even have to do any of the work. Cain, at the very least, seems like he’s making pitchers work. This has been one good thing.

Pretty obviously, it’s too early to learn much from our 2016 regular-season sample sizes. In most cases, we just need to be patient until the sample sizes grow, over the course of weeks or months. We go through this every single year, and it’s just part of re-transitioning into the baseball routine. But what if we could work backwards? Take Kelvin Herrera. What if we could increase his sample size by including last year’s playoffs? It sounds weird, but I’ll tell you why it’s possible: Just in time for the playoffs, Herrera started doing something. He’s continued that something into 2016, and it’s made him unfair.

I’m not even deterred by the fact that I wrote about this last October. I generally don’t like repetition, but it’s a new year, now, and Herrera’s keeping it up. So I won’t stop until more people understand that Kelvin Herrera now possesses a reliable breaking ball, and that goes with his blazing heater and high-80s changeup. The breaker comes in around 81 – 84, and based on what we can see, this is turning Herrera into a monster.

On Sunday, with two outs in the bottom of the seventh, Boston reliever Noe Ramirez fielded a comebacker off the bat of Toronto center fielder Kevin Pillar. He flipped it to Hanley Ramirez for the putout. It wasn’t a particularly momentous occasion, but it got me thinking — was this the first ever Ramirez to Ramirez putout in major-league history? I probably would have let it go right there (I’m pretty lazy, after all) but Jim Reedy pointed out that there have only been 29 Ramirezes in major-league history, and that didn’t seem like to daunting of a number. So I dove in.

Let’s start with the video. And then the words. Because you might not spot everything in the video the first time through. It sorta looks like an everyday foul ball, maybe with some sort of inside joke at the end. Trust me, though, this moment is fairly epic.

Paul Konerko‘s reaction provides our first clue that something was a bit different about this swing. He’s animated, talking to the third base coach about something. Zack Greinke’s doing a bit of stomping around after he watches it go.

“There are guys that take so quickly that it almost forces you to throw strikes,” Greinke told me at Spring Training earlier this month. “Paul Konerko, he would change his stances all the time, but there was this one time where he had this new stance where it looked like he wasn’t even getting ready and then all of a sudden you go and he’d swing.”

I laughed out loud. He was quick-pitching you! “Yeah,” Greinke agreed. “Before release, I think, oh, he’s taking, and you’d get overconfident. He only did that for a month or so.”

Go back and look at the video. It’s not quite a bat on the shoulder, but there is something about Konerko’s setup that seems lackadaisical. Given the 1-0 count, it looks like he’s waiting for Greinke to get himself in a deeper hole. “A guy like that, you think most pitchers would be coming with the fastball, but he’s liable to give you another slider out of the zone,” agreed Konerko when contacted by phone about the at-bat. “And then sometimes, he’d even take something off when he was supposed to come at you.”

So maybe Konerko was just taking, and that’s why it took him so long to get ready? Not quite. It did take him a long time to get ready back then. On purpose. “I used to be too tense too early before the pitch came,” Konerko remembered, “so sometimes I would wait to see how long I could wait. I was so ready to hit that it didn’t help me.” So, in the footage here, Konerko actually is attempting to chill out as long as possible, but not so much to mislead Greinke as to prepare himself optimally.

There were 13 pitchers who appeared in a Monday afternoon spring-training contest between the White Sox and the Royals. The game took place in one of the few ST venues equipped with PITCHf/x, and to no one’s surprise, the fastest average fastball on the day was thrown by Yordano Ventura. Showing up in second place was one Brandon Brennan, and then in third place, you find Chien-Ming Wang. Just in case you’re wondering, no, there is not a second Chien-Ming Wang. This is not, like, the son of the original Chien-Ming Wang. This is the original Chien-Ming Wang, throwing harder than Daniel Webb. He threw harder than Joakim Soria. He threw harder than Carson Fulmer.

It’s one appearance, and it’s March. Wang worked out of the bullpen, as opposed to being a starter. It’s not like we get to just turn the clock back 10 years, but here’s something Wang said after the game:

Chien-Ming Wang said his velo was 88-89 last year. Now 94-95 thanks to pitching guru Ron Wolforth. #Royals

— Jeffrey Flanagan (@FlannyMLB) March 15, 2016

If we wanted to turn the clock back 10 years, we’d insist on Wang re-discovering old velocity levels. Now he has. Now we have proof. Chien-Ming Wang was once a hell of a Yankee, and though you might’ve forgotten about him, he never forgot about his success.

Retirement announcements are seldom surprising, because even from the outside it’s pretty simple to tell when a player has outlived his utility. Willie Bloomquist is 38, now, and after spending the offseason making up his mind, he tweeted the following last Friday:

Make your last swing your BEST swing. Farewell @MLB. Thank you for 14 amazing seasons. It’s been an incredible ride. pic.twitter.com/VuImzqOrSl

— Willie Bloomquist (@williebloom) March 11, 2016

Bloomquist is hanging them up, which means Bloomquist articles on analytical websites must also hang them up. In a way it’s amazing Bloomquist achieved such Internet fame in the first place, being a career reserve, but his name meant a little something over the years, and here, for one last time, I want to talk about what Willie Bloomquist was.

The one conversation we continue to have about the Royals to this day is whether there’s just something about them that the numbers aren’t seeing. I think we’ve all agreed the Royals have deserved to be pretty good of late, but to be as good as they’ve been — let’s face it, the pro-Royals side has plenty of ammunition. They’ve played like something greater than the sum of the roster’s parts, and that’s where there could be a disconnect. One idea is that a team is the sum of its parts, plus or minus however much randomness. A counter-idea is we’re missing some kind of human element, in our haste to try to see the future. This would be where the Royals have perfected a magic formula.

If there’s one player who might adequately represent the Royals in a nutshell, it’s Salvador Perez. You could always try to go with Alcides Escobar, on account of #EskyMagic, and that’s fine, but I think Perez is a little more fitting. Perez is still young, and he’s obviously talented. Looking at his numbers, there are things for us to like, and there are things for us to not like. Objectively, Perez appears to be a good but flawed player, yet if you listen to the Royals themselves, they think of him as the heart and soul. They see him as the most important player on the roster, and over the last three years, the Royals have won 57% of the time when Perez has started, and they’ve won 49% of the time when Perez has been on the bench. Just as there might be something about the Royals, there might be something about Salvador Perez. It’s just another conversation for all of us to have.

One conversation we never needed to have: whether Perez’s old multi-year contract was team-friendly. It was stupid team-friendly. More than maybe any other deal, depending on your own Perez evaluation. Teams don’t often willingly amend such lopsided agreements, but the Royals wanted to keep Perez happy. So now that old contract has been torn up, and Perez has been more adequately rewarded for everything that he’s meant.

Call it a smart and atypical move, on the Royals’ part. Call it a necessary move, on the Royals’ part. There are plenty of team-friendly contracts out there, but not many to such an extent, so we don’t have a lot of situational comps. All that’s really important here is that Perez is being treated fairly. Maybe this is something the Rays would’ve been willing to do, and maybe it’s not. Perez just cares that the Royals did it.
