Whenever a player or team perform exceptionally well, a common question we get in our chats is, “is this the real player/team?” Usually, the answer is no — a hot streak is a hot streak, a fluke level of performance above the norm. Every so often, though, the outlook’s a little fuzzier, especially when it comes to individual players who might be having a breakout. Yet in the case of the Nationals’ rotation, we can declare unequivocally that no, this is not the real them. The Nationals’ starting rotation is good. Over 51.2 innings, between June 3 and June 10, Nationals starters didn’t walk a single batter.

And they struck out 51 batters. According to Adam Kilgore, that hadn’t happened in at least a century. We can say with certainty that the Nationals’ starters aren’t this good because, over that span, they posted a 1.66 FIP, putting them somewhere between Craig Kimbrel and peak Pedro Martinez. They achieved a strikeout-to-walk ratio of #UNDEFINED, and a K% – BB% of their K%. The Nationals’ rotation, without question, overachieved, but everyone who’s ever thrown a perfect game has overachieved, and those perfect games have drawn an awful lot of words. So the Nationals deserve some words of their own, before this streak is forgotten.

If you were to conduct a casual survey among baseball fans about the greatest pitching season of all time, there’s no doubt that there’s a few years that would pop up regularly among the responses. Bob Gibson‘s 1968, certainly. Dwight Gooden‘s 1985 would probably appear, or Roger Clemens‘ 1986, or Steve Carlton’s 1972. Randy Johnson has a few years you could point to. So does Sandy Koufax. So does Greg Maddux. There’s not really a wrong answer there, because it’s not a question that can be answered. Run environment and park effects have to be measured, and we can do that to some extent, but we can’t really account for the fact that some people prefer the quiet mastery of Maddux to the flame-throwing mastery of Johnson, or the fact that whether you were 15 in 1968 or still decades away from being born will absolutely color your memories of particular eras.

For me, the answer is a tie. It’s either Pedro Martinez‘ 1999 or Pedro Martinez‘ 2000, and it’s not hard to explain why. They were legitimately great seasons no matter how you looked at them, and they occurred right in the face of some of the highest offensive environments we’ve ever seen. It’s why Martinez’ ERA+ in 2000 was 291 while Gibson’s 1968 was 258, despite Gibson’s raw ERA of 1.12 being considerably lower than Martinez’ 1.74. And for me, I lived in Boston at the time. I was in college. I lived within walking distance of Fenway Park. I can’t say I specifically remember any starts of Martinez’ I saw in person in those two years, but I’m sure I saw at least a few.

Martinez, in those two years, did something no other qualified pitcher since 1900 has ever done before or since. He struck out more than 11 per nine, and he paired that with a walk rate below 2.00. That’s a bit biased towards recent pitchers, since the game as a whole simply didn’t strike out decades ago like they do now, but that doesn’t really change how fantastically impressive it was.

Now, realize this: This isn’t a post about Pedro Martinez. It’s a post about Stephen Strasburg, who, through his first 14 starts of the season, is on pace to do exactly that… not that anyone seems to be noticing. If it’s possible to be both a superstar and feel like a disappointment, considering how hyped Strasburg was as the No. 1 pick in the 2009 draft, he’s managed to accomplish it.

Each weekday during the minor-league season, FanGraphs is providing a status update on multiple rookie-eligible players. Note that Age denotes the relevant prospect’s baseball age (i.e. as of July 1st of the current year); Top-15, the prospect’s place on Marc Hulet’s preseason organizational list; and Top-100, that same prospect’s rank on Hulet’s overall top-100 list.

Summary
Payano has two interesting pitches from the left side, but he’s been derailed by inconsistency his whole career.

Weird things about baseball fascinate me. One of those things is the concept of discarded players. Every once in awhile, you’ll see a player doing well and think to yourself, “Hey, wasn’t he on our team at one point?” David Carpenter is one such player. Watching him face the Red Sox this week, I couldn’t help but think that it would be sure nice if the Sox had him right now instead of Craig Breslow. Sure, the world will keep on spinning, and Carpenter wouldn’t make or break the 2014 Red Sox, but every little bit counts, and the Red Sox gave him away for free after just five weeks on the roster. In situations like these, we often jokingly say (or at least I do), “Hey, I wish we could get guys like that!”

I don’t mean to pick on the Red Sox, because every team does this. If you scan rosters, you’ll find one such player on just about every roster. And originally, my intention was to run down that list and look at them all individually. But then I got a look at this trade. On July 31, 2010, the Atlanta Braves traded Gregor Blanco, Jesse Chavez and Tim Collins to the Kansas City Royals for Rick Ankiel and Kyle Farnsworth. Take a look:

Pitch-pattern data can be interesting when you’re trying to spot trends or adjustments for scouting reports. Changes in pitch patterns can sometimes be revealing. Just the other day, we looked at Miguel Cabrera, and beginning in last year’s playoffs, pitchers started to challenge him with more fastballs over the plate. That trend continued into this April, as opposing teams picked up on the fact Cabrera wasn’t 100% after offseason surgery. With Cabrera not swinging like himself, pitchers often tried to blow him away. Now Cabrera’s getting back to normal, so pitchers, one figures, should soon return to their normal. Not that it’ll do them much good.

Pitch-pattern data can also be interesting and revealing when it doesn’t change. Wilin Rosario doesn’t see many fastballs, or strikes, or fastballs for strikes. What’s revealed is how people think of Wilin Rosario and his eye. The way Rosario gets pitched is perfectly justifiable, and this is an example of baseball finding its equilibrium. Yet there’s something curious I’ve noticed about Anthony Rendon. His name has come up when I’ve been researching other things.

Perhaps we should be used to this by now. Just four years ago, Craig Kimbrel was just some guy who walked more than 18 percent of the batters he faced. Now, he’s Craig Kimbrel. In the same timeframe, Drew Storen went from talented rookie set-up man to closer on a suddenly not terrible Nationals team. In their wake, young relievers like Kenley Jansen, Kelvin Herrera, Trevor Rosenthal, Addison Reed and others have taken the baseball world by various degrees of storm. And there was this Aroldis Chapman guy, too.

This season has been no different. Seemingly anonymous relievers have been springing from the figurative woodwork to capture spots on the top of various reliever leaderboards, most notably K% and velocity. Let’s meet some of them, shall we?

With the real Opening Day behind us — sorry Astros and Yankees, you’re just late — we now have real 2014 data from almost every team on the leaderboards. Of course, besides answering trivia questions, we all know that there’s really nothing insightful to be learned from one day’s performance, and we’re not going to find useful information to be analyzed there until the samples get a lot bigger.

But there are some numbers that became useful in very short order. Strikeout rate, for instance, only has to be regressed 50% to the mean at a much lower number of batters faced than most other pitching metrics, and big changes in K% over even a few starts can prove somewhat meaningful. It’s hard to fluke your way into getting a bunch of Major League hitters to swing through your pitches, and if you’re consistently throwing pitches by people, it’s a pretty good sign for the future.

FanGraphs recently added the ability to view Inside Edge fielding data breakdowns to player pages, and it’s a fun way to look at defense. Milwaukee’s Carlos Gomez converted the highest percentage of “Remote” (defined as being 1%-10% likely) plays, not unexpected given his stellar defensive reputation, while Brandon Crawford and Pedro Florimon tied for the largest raw number of such plays, at 24, also not unexpected since they are shortstops who are mostly in the big leagues for their defensive value. You can view this data in any number of different ways, really. By definition, no major leaguer converted a single “Impossible” play, but the two players who had the most such plays head their way were Cincinnati outfielders Jay Bruce and Shin-Soo Choo, who had a combined 250 “Impossible” plays. That the top two players both played on the same team tells us… something, probably.

But we’ve already looked at Crawford’s greatness, and Florimon just really isn’t that interesting. What I’m thinking about today are the 90%-100% plays, defined as “Almost Certain / Certain” for our purposes. Those are the plays that are so routine that most every major leaguer should be converting nearly every such opportunity into an out, and for the most part, they do. Nine qualified big leaguers made 100% of those plays last year, including the defensively-maligned Choo, which tells you a little something that his issues were more with his routes and speed in center than they were with making plays on the balls he got to. (Which sort of makes him sound like the Derek Jeter of center fielders, doesn’t it?) 44 players converted at least 99% of those plays. 60 got to at least 98%. Every team made at least 97.2%; as a whole, the sport converted 98% of such plays.

This is all as you’d expect. Those are the routine, mundane, barely thought-of plays you see a dozen times a night. They’re just short of extra points in football; they’re made all the time because they should be made all the time. You don’t notice them until they give you a reason to. The rankings tend to overweight outfielders, because there’s of course a smaller likelihood of making a throwing error from the outfield. But someone has to be pulling up the rear, and that’s what I wanted to know: which big leaguer (non-catchers, for simplicity) was the worst at making the easiest play? Read the rest of this entry »

It would be hard to call Livan Hernandez’s retirement surprising, but some people such as myself were probably a bit taken aback because we assumed he had already retired. That is not meant as a slight. Hernandez is in his late thirties (some would say he is even older), did not pitch at all in 2013, and was dreadful when he last pitched in the majors in 2012. Our own Paul Swydan ranked Hernandez’s 2012 as one of the worst final seasons among pitchers having similar careers.

Beat writers and fans of Hernandez’s numerous teams will have all the best stories and reflections on his career. It would be hard to top Grant Brisbee’s (understandably) Giants-centric farewell to Hernandez, so I am not even going to try. But Hernandez drew attention, even late in his career, for other, non-fan-centric reasons. In 2011, Jeff Sullivan (who today [Livan Day at FanGraphs!] also posted about Hernandez and the strike zone) mentioned that Hernandez had a pretty bad slider in 2011. Yet after that same 2011 season, Swydan noted gave Hernandez an honorable mention for his incredibly slow, but amazingly curvy curve in 2011. Robert Baumann also got in on The Joy of Livan.

Rather than getting into every little statistical detail of Hernandez’ career, let’s look at three different moments from the roughly the beginning, end, and middle of his career.
