Heading into the 2012 season, Baseball America wrote of DJ LeMahieu, “Most scouts see him as a singles hitter who doesn’t provide enough beyond his batting average.” BA added that “his fringy speed and quickness don’t fit at second base.”

The latter turned out to be patently false. The 27-year-old won a Gold Glove at second base with the Rockies in 2014, and he remains a solid defender. He doesn’t look like a middle infielder — LeMahieu is 6-foot-4 — but his plus-2 DRS over the last two years puts him solidly in the gets-the-job-done category.

From an offensive standpoint, the singles-hitter label has a grain of truth to it. Despite calling Coors Field home, LeMahieu doesn’t leave the yard very often. Extra-base hits aren’t his forte (last night’s home run and pair of doubles notwithstanding). And while he’ll accept a free pass — his walk rate is a respectable 8.3% — no one is about to compare him to Eddie Yost.

Not too long ago, FanGraphs editor Carson Cistulli was watching a broadcast of a baseball game during which the announcer remarked offhandedly that the pitcher’s batting average of .231 was equivalent roughly to a .400 mark for a position player. His interest piqued, Cistulli asked his FanGraphs colleagues: if not .231 precisely, then what is the equivalent of a .400 batting average for a pitcher? After nobody else expressed any interest in doing the same, I endeavored to answer the mostly frivolous question.

The easiest way to go about solving the problem is probably to look at percentile ranks — that is, at seasons from position players, broken into percentiles by batting average, compared to the same percentiles for pitchers. That’s where I started, at least. I looked at all qualified position players from 1986 to 2015, finding nearly 5,000 player-seasons. Then I turned to pitchers. Because no pitchers qualified for the batting title during that time range, I chose a threshold (a somewhat random figure of 50 plate appearances in a season), yielding nearly 1,500 pitcher player-seasons.

I created percentiles for both groups and set them at 10%, 33%, 50%, 67%, and 90% to yield averages. The table below shows the results:

How do you know when a knuckleball pitcher is good? It’s not an easy question to answer. We know it’s not just a matter of having a knuckleball — there have been bad knuckleball pitchers. But the pitches themselves aren’t easy to scout, and the whole idea behind an effective knuckleball is sort of the lack of consistency. There’s not a large sample of these pitchers to examine, which further complicates things. A knuckleballer is the most unusual player type in the game, someone who can be almost impossible to trust, but someone who also throws a pitch that seems almost impossible to hit.

There’s a line somewhere. There has to be. There’s a line beyond which a knuckleball pitcher is legitimately good, and maybe that’s when he throws 60 good knuckleballs out of 100, or maybe it’s when he throws 90 good knuckleballs out of 100. We’ve seen R.A. Dickey be an ineffective knuckleballer, and we’ve seen him be an effective one. The pitch gave his career a second chance, which is one of its magical aspects. At some point, I suppose, you just have to look at the numbers. The numbers will tell you when a knuckleballer is working. I don’t know of any other approach, and what the numbers are indicating is that Steven Wright has mastered the weirdest pitch in the sport.

Heading into the season, there was probably no more polarizing team in baseball than the Diamondbacks. Despite adding Zack Greinke, Shelby Miller, and Tyler Clippard over the winter, our preseason forecasts pegged Arizona as a 78 win team, a win worse than they finished a year ago. The organization themselves saw a wildly different picture, and so many articles were written about the divide that I had to write a piece in March trying to dispel the notion that we had some kind of bias against the franchise.

You know what’s happened since then. First, the team suffered a devastating loss when A.J. Pollock’s lingering elbow issues turned into a season-ending injury right before Opening Day. Then Zack Greinke gave up seven runs in his first regular season start with the team, and struggled through a slow start to the season. Then Shelby Miller imploded, pitching worse than any other starter in baseball this year. And now it’s the end of May and the team is 23-30, already nine games behind the Giants in the NL West race.

But this isn’t a post gloating that we were right all along. In reality, some of the D’Backs optimism surrounding their team has actually been more correct than our pessimism about the team’s chances, if you look beyond the overall record, anyway. Our projections didn’t like the Diamondbacks because it had a negative view of their role players, thinking that this was basically a stars-and-scrubs team that relied too heavily on a few elite players. But so far, those role players have been carrying the team, keeping it afloat while the big names struggle.

Last week, Rian Watt published a terrific piece at Vice Sports on the growing use of wearable technology by Major League Baseball teams for purposes of collecting players’ biometric data. If you haven’t read Watt’s article, go check it out, it’s fantastic. In short, though, the piece explores the ethical implications of MLB teams asking their players to wear devices — such as the Readiband sleep monitoring system recently employed by the Seattle Mariners — that collect data that can not only be used for purposes of fine-tuning players’ on-field performance, but also potentially for roster- and contract-related decisions as well.

For instance, while the sleep-tracking data provided by Readiband could certainly help players adjust their sleep patterns to maximize their chances of performing at a peak level on the playing field, this data could also give teams insight into a player’s habits undertaken in the privacy of his own home. It’s not hard to imagine a team ultimately incorporating such information, or other forms of biometric data, into their player evaluations in ways that may ultimately harm a player’s career prospects or earning potential.

In addition to the ethical considerations surrounding the use of these technologies explored in Watt’s article, the collection of biometric data by MLB franchises also has potential legal implications as well. As Watt notes in his piece, wearable technology may very well become an issue during this year’s collective-bargaining negotiations between MLB and the Major League Baseball Players Association. Indeed, Pirates’ infielder Cole Figueroa recently mentioned during an episode of the Effectively Wild podcast that a number of MLB players are growing increasingly concerned over the potentially adverse consequences of the growing use of this technology by their teams.

It was an inauspicious start to the season for Michael Feliz. It’s been an inauspicious start to the season for the entire Houston Astros ballclub. One of them’s turned it around, providing hope to the other.

Feliz’s numbers, on the whole, are impressive, and even they come with something of an asterisk. In 20 innings of relief work, the 22-year-old right-handed rookie has struck out 33 batters and walked four — only two pitchers in baseball currently have a better K-BB%, and they both wear pinstripes. You’ve probably heard of them. The asterisk is that Feliz has walked just four batters all year, and they all came in his season debut, a 107-pitch relief outing back on April 6 after starter Collin McHugh recorded just one out. Feliz was thrust into action in the first, asked to eat innings, faltered, and was promptly sent to the minors for a fresh arm. He was recalled a couple weeks later, and since then, he’s been completely unhittable.

Dating back to that April 26 recall, Feliz has struck out half of the batters he’s faced, and he’s walked none of them. He’s getting ground balls, and he’s working multiple innings. Before the year, you might’ve only known Feliz’s name by being an Astros fan or a prospect hound — while he fell just outside of preseason top-100 prospect lists, most evaluators viewed him as a top-10 piece in a deep Astros’ system. Now, he’s turning heads, with the kind of numbers that practically demand attention.

On Monday, the White Sox lost 1-0, so that makes things fairly uncomplicated — they lost because they didn’t score. It happens. Also, they ran into Matt Harvey, and the Mets had reportedly identified a problem with Harvey’s mechanics beforehand, so if Harvey’s back on track now, well, there’s no shame in losing to him. Matt Harvey is an ace, and sometimes aces shut people out.

That’s how the White Sox lost their most recent game. Now let’s talk about the previous games.

Chad Bettis throws both a cutter and a slider. Or maybe he throws cutters but not sliders? That determination largely depends on how you parse pitches. Whatever your opinion, you probably won’t get much of an argument from him. The Rockies right-hander isn’t 100% sure himself.

“Both,” was Bettis’s initial answer to my ‘Cutter or slider?’ question. That was followed by less-than-definitive elaboration.

“It’s the same grip; it’s just me manipulating it to make it shorter or bigger. With one, I’m more behind the ball and with the other I’m a little more on the side of it. When I want to make it a little sweepier, I can. When I want to make it short and tight like a cutter, I can do that too.”

Bettis had a slider at Texas Tech, although he’d already begun developing a cutter by the time Colorado selected him in the second round of the 2010 draft. Prior to last season, the cutter is all he’d thrown in pro ball.

The reintroduction of a slider — if that’s what you choose to call it — came about mostly by accident. Read the rest of this entry »

When the December three-way trade between the Chicago White Sox, Cincinnati Reds, and Los Angeles Dodgers was announced, you could sense Dodgers’ fans frustration. “Dodgers, Reds, Sox Complete Three-Way Trade Centered Around Todd Frazier,” is a great headline if you’re a Dodgers fan. Until you realize that Frazier isn’t coming to Tinseltown. Surely this was a mistake. After all, Justin Turner was having knee surgery, and how good is he, really? “We need Frazier!” the people of Los Angeles almost certainly said.

Well, it didn’t work out that way for the boys in blue. And, as it turns out, that’s just fine, as Trayce Thompson has been a revelation this season.

Before we get into why and how he’s been a revelation, I want to share a brief nugget of FanGraphs history with you. At one point, we had been considering a book project, and we crafted a few sample pages for it. On one, we placed blurbs for four players, one of whom happened to be Thompson. Here’s the blurb Carson Cistulli wrote for him (click to embiggen):

So, whenever I see Trayce Thompson’s name, I think of this, and it makes me smile. As I think you’ll agree, that blurb is Vintage Cistulli.

Danny Salazar has a fastball that averages nearly 95 mph and one of the best changeups in the game. Given that lethal combination, it’s no surprise that he’s striking out over 11 batters per nine innings and has a 2.32 ERA. In his age-26 season, the Indians right-hander is continuing his ascent into most-overpowering-pitchers territory.

Signed by Cleveland out of the Dominican Republic in 2006, Salazar began emerging as a top-shelf prospect after returning from Tommy John surgery in 2011. Two years later, he was in the big leagues with a heater that touched triple digits. Last season, he logged career highs in wins (14), innings pitched (185) and strikeouts (195).

Salazar talked about his repertoire, which includes a changeup with a unique grip — no, it’s not a splitter — when the Indians visited Fenway Park earlier this month.

———

Salazar on why he’s emerged as a front-line pitcher: “I think it’s learning. Every time I go outside, every time I watch a game, I’m paying attention. I’m seeing how guys attack hitters. That’s helping me to become a better pitcher.

“You learn about yourself and you learn about hitters. My best pitch is a fastball, but I know that if I’m just throwing fastball, fastball, they’re going to do damage to me. I have to use my secondary stuff, too. I’m learning more about myself and more about the other teams and how to attack them.”
