I recognize that this is a sensitive subject at a lousy time. I mean, the Mariners are winning, winning on a fairly sustained basis, and Felix Hernandez owns a lower ERA than Stephen Strasburg and Noah Syndergaard. According to our playoff odds page, the Mariners have a better than 50% chance of getting to the postseason, which for Felix would be his first-ever taste of those stakes. Mariners fans aren’t looking to be worried. Not now, not when they have circumstances to appreciate.

So I know this post might be interpreted as a bit of a bummer. It’s not meant that way; these are just observations. And no part of me presently thinks that Felix is toast. It’s just, there are things to talk about. What Felix has been doing, he’s never before done quite like this. It’s looking like he could be beginning a new chapter.

Heading into the season, there were a lot of question marks about the Dodgers rotation, but so far, the team’s struggling offense and bullpen have received a big boost from a pitching staff led by Clayton Kershaw and Kenta Maeda; their starters currently rank fifth in WAR. Ross Stripling has been a nice early surprise for the team, and while Alex Wood’s ERA remains too high, his underlying metrics suggest that he still can help the team. Scott Kazmir’s struggles are perhaps most worrisome, but if he can stop giving up home runs, he should be serviceable as well.

And if any of the big leaguers falter, there is help on the way. In the minors, Jose De Leon made his first start of the 2016 season on Tuesday, the delay being partly due to a minor ankle injury and also the product of an effort to keep his innings low in the early going. When de Leon’s debut came the day before Julio Urias’ most recent start, I decided to watch both via MILB.tv.

Just a couple weeks back, Dave Cameron examined the things that should worry us about Dallas Keuchel. He was more nuanced, but we could break it down into three components: lower velocity, fewer calls on the black, and fewer swings. For a guy that had the third-lowest zone percentage in baseball last year, the latter two seem hugely important for his success. So I asked the Astros’ lefty what he’s doing about those things.

Lower Velocity

Asking a pitcher about velocity is a delicate thing. Big increases mean whispers, and big declines mean… whispers of another sort. And then there’s the brutal march of time that fritters away our athleticism, day by day. You walk on egg shells.

But they know their radar-gun readings. And though age should have stolen about a tick from Keuchel, it looks like he’s down more than a tick and a half on the radar gun, from 89.6 mph last year to 88.0 this year. But that’s comparing all of last year to this year’s April, and also ignoring a slight uptick in recent games. If you compare last week’s velocity to last year’s April velocity, Keuchel is only down 0.8 mph, well in the normal range for a 28-year-old pitcher.

The case has been made for Carlos Correa. It was even made on this very site last year. He was the number one overall draft pick. He was last year’s American League Rookie of the Year. He’s been called Alex Rodriguez, with better makeup. He’s even been called the best player in the major leagues (maybe). When we ran our preseason staff predictions a couple months back, 11 of 55 FanGraphs employees chose Correa to win the American League MVP. Beside he and Mike Trout, no other player received more than four votes. The public opinion on the matter seems almost unanimous: Carlos Correa is viewed as baseball’s best shortstop, just 126 games into the 21-year-old’s major league career.

But there’s a 22-year-old, just 123 games into his major league career, who wasn’t Rookie of the Year and received zero preseason MVP picks, whose case for baseball’s best shortstop might be just as strong as Correa’s. It’s time we consider whether it’s actually Francisco Lindor who is baseball’s best shortstop.

The argument might not have to be complicated. Correa gained his status so quickly due to the hype and the performance. Both need to be present for a player to be accepted as a bonafide superstar in less than a calendar year. It’s when the two collide that lofty claims like “baseball’s best shortstop” or “MVP candidate” start to seem reasonable. So let’s start with the hype.

Yesterday, Daniel Murphy went 4-5, hitting his fourth home run of the season in the process, and driving his batting line for 2016 up to .398/.449/.663. His 192 wRC+ ranks third best in the big leagues, and he’s behind only Manny Machado, Dexter Fowler, and Mike Trout on the WAR leaderboards. In the aftermath of yesterday’s hit barrage, I sent out the following tweet.

Daniel Murphy for 3/$38M now looking like the free agent steal of the winter.

— David Cameron (@DCameronFG) May 4, 2016

Many of the responses argued that Fowler is ahead in that race, which is certainly a reasonable argument given what he’s done for the Cubs thus far. A bunch of other responses were essentially along the “small sample size” lines, though. Like this one, for instance.

@DCameronFG Is there any reason to expect the 25 game sample to trump the 900 game sample that preceded it? We know who Daniel Murphy is.

— Rational Sports (@Rational_Sports) May 4, 2016

In general, the premise of this tweet is mostly correct. When you have a large sample of a player’s career performance, you shouldn’t overreact to a 25 game hot streak, and believe that the most recent performance cancels out the longer history the player has provided for evidence of what he’s capable of doing going forward. In Murphy’s case, though, we’re well past the point of this being a 25 game hot streak. For most of the last year, Daniel Murphy has been one of the best hitters in baseball.

There’s a vestigial anchor from my baseball past that I drag around — it’s called Red Sox fandom, and it’s attached to a barely seaworthy vessel whose form is an email group of mainly older Boston fans. Most of the debates that happen on the email chain are really just individual manifestations of the argument surrounding process vs. outcome. Like a lot of traditionally-minded baseball fans, most of the members of the group are outcomes people, as baseball fans have been taught to be for the past 100-plus years — focusing on ERA, batting average, etc. I tend to find myself more on the process end of the spectrum, and lately I’ve been thinking about this debate as it relates to pitching — and especially as it relates to Noah Syndergaard. 

You could argue that no one’s process is better than Syndergaard’s right now — and, most recently, Jeff Sullivan actually has argued that. If the goal of pitching is to limit base-runners — and thus limit runs — the right-hander is about as good as it gets. I like quick ERA estimators like strikeout- and walk-rate differential (K-BB%) partly because I’m lazy and partly because I think they’re nifty, and currently Syndergaard is second in K-BB%, which is the best quick ERA estimator we have. Strikeouts? Elite. Walks? Elite. Velocity? Arsenal? Unparalleled. The processes he’s taking to influence positive outcomes are second really only to Clayton Kershaw this season, and for the most part, he’s been rewarded for them. But there is one glaring issue he still has — laid bare in his past two starts — which we’ll get a lot of chances to see below.

All of that said, the main question we’re going to be answering today is: how does a team score runs off of Syndergaard? Every pitcher has to give up runs at some point, no matter how impressive their talent. Today, we engage in a fun exercise to examine those runs. So let’s go through a month’s worth of starts!

A primer for what we’re about to discuss: looking at Statcast data through Baseball Savant, Syndergaard has the lowest average exit velocity among pitchers with a minimum of 60 batted-ball events. Those events include both hits and outs, and it’s testament to the type of contact against him — and the frame for a lot of what we’ll be looking at today. Here’s a reminder of what exit velocity generally means for outcomes. Now let’s jump in, with the understanding that we’re going to skip over his first start of the season, as he didn’t give up any runs. Onward!

Start #2, 4/12/16, 1 ER: Derek Dietrich single. Exit velocity: 74 mph.

Devised originally in response to a challenge issued by sabermetric nobleman Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game. Read more about the components of and formulae for NERD scores here.

Most Highly Rated Game
Washington at Chicago NL | 20:05 ET
Ross (22.2 IP, 105 xFIP-) vs. Hendricks (23.0 IP, 73 xFIP-)
Of the 136 starters to have recorded 20-plus innings so far this year, only five have recorded a lower average fastball velocity than Cubs right-hander Kyle Hendricks. Two of those five are knuckleballers. Another is Jered Weaver, whose fastball is so slow… How slow is it?… It’s so slow, one could author a slim collection of poorly conceived and executed jokes just like this one about it… And yet, what one finds is — despite Hendricks’ relative dearth of arm speed — is an equal and opposite amount of success. He induces grounders. He hardly walks anyone. He’s posted a league-average strikeout rate. Today, he also starts for the Cubs.

Bryce Harper was in a slump! You might not have noticed. Right around the middle of April, it seemed people decided Harper had somehow taken another step forward. And maybe he has, I don’t know, but if he has, he hasn’t done it since the middle of April. As a matter of fact — I’m writing this late Wednesday, and when I look at the leaderboards over the past seven days, Harper is tied for dead last in WAR. I don’t recommend you make a habit of looking at WAR over seven-day periods, but Harper is Harper, and last is last. There was a real and legitimate slump. Could be there still is.

Let me make it clear right now that I’m not concerned. Not about Harper, not at present. I thought he was great at the beginning of April, I thought he was great in the middle of April, and I think he’s great now at the beginning of May. Everyone is entitled to the occasional off-week. I just do think there’s something we could learn from examining how what’s happened has happened. Bryce Harper slumped! Why?
