Hendricks (41.0 IP, 75 xFIP-) vs. Bumgarner (58.2 IP, 85 xFIP-)
It doesn’t require a brain surgeon to recognize that a game featuring two of the league’s more successful pitchers and more successful clubs — that such a game would possess some interest for the public. There’s also no reason to believe, however, that a medical doctor trained specifically in the field of neurology would be particularly well-suited to diagnosing the likely aesthetic value of such a game. There are a number of neurosurgeons, presumably, who have almost no familiarity with the Pastime. Like Nate’s dad, for example. He’s a neurosurgeon, but what does he know about sport? Nothing, is what.

The numbers suggest that Khris Davis should be labeled a power hitter. Since the beginning of last season, the Oakland outfielder is hitting .244/.308/.504 with 39 home runs in 603 plate appearances. This past week, he had a three-homer game capped off by a walk-off grand slam.

A few days before his heroics, I opined to Davis that he’s best described by said label. He demurred.

“That’s arguable,” answered the 28-year-old former Brewer. “It’s just what everybody’s judgment is of me. I don’t think I’m a power hitter.”

Color me a skeptic. Not only is Davis among the league leaders in home runs this year, he went deep 21 times over the second half of last season. If he’s not a power hitter, where are the bombs coming from? Read the rest of this entry »

Smyly (49.2 IP, 85 xFIP-) vs. Fulmer (19.1 IP, 85 xFIP-)
The virtues of Drew Smyly as a pitcher are what Thomas Jefferson — and also anyone who possesses some facility with English — might describe as “self-evident.” As for Michael Fulmer’s virtues as a pitcher, those are decidedly less evident at the moment. Because one of the things he’s done is to concede earned runs at a rate about 50% higher than an average pitcher. By this measure, his virtues are rather obscure. But look: he’s produced a fielding-independent line that’s roughly a standard deviation better than the average starter’s. And a sitting fastball velocity more than a standard deviation better. And he’s also more than a standard deviation younger than the average starter. The marginal return on your psychic investment in Michael Fulmer is likely to be enormous. Thanks to Michael Fulmer, you’re going to be flush with psychic currency.

Marcell Ozuna is the third-best outfielder on his team. He can’t match the power and discipline of Giancarlo Stanton, and he can’t match the patient, contact-oriented approach of rising star Christian Yelich. Partially related to those two statements, Yelich and Stanton have signed contracts worth nearly $400 million total while Ozuna, despite possessing more service time than Yelich and having played 50 more games than Stanton since the start of 2014, will be paid near the league minimum this year. Ozuna is off to a great start this season, and we might want to look for changes to his game after a rough 2015 season, but Ozuna is very much a similar player to the one that slugged 23 homers back in 2014.

Ozuna has a fairly unique game. He has good power, but in more than 1500 plate appearances, it has only shown up as average with a .157 ISO. He walks at a below average rate (6% for his career), strikes out at a below-average rate (23% for his career), and has maintained a high .331 BABIP. Together, it has made him a roughly average offensive player, and a difficult home park elevates his wRC+ to 104. Not too bad. On defense, Ozuna has recorded nearly 3,000 innings in center field and both UZR and DRS place him right at average. Average offense and average defense in center field combine for an above-average player. Average to above-average might sound a bit boring, but Ozuna’s streaky performance and perceived inconsistency means he gets to his stats in rather exciting fashion.

Ozuna has had one really good year, in 2014, followed by a disappointing season in 2015 that saw him receive a demotion in the middle of the season, although that demotion might have been tied more closely to Ozuna’s super-two status and his agent Scott Boras rather than any strict performance-related deficiencies. This season, Ozuna is back, picking up where he left off at the end of 2015 and playing like the player who exhibited so much promise two seasons ago. How long will this last? It’s hard to say.

Yes. What is wrong with Matt Harvey? Because if you watch him pitch, it seems like everything is wrong, and yet nothing at all. At least, it’s hard to put your finger on it. You run down the list of things that could explain why he has an ERA near five and the worst ERA estimators of his career, and you find little things here or there. But do you find a smoking gun?

Last week, Jeff Sullivan showed how easily pitchers can exploit the flaws in Yasiel Puig’s approach right now; simply pitch him away. He’s swinging at something close to two-thirds of the pitches on the outer third of the plate or further outside; the league average on those pitches is roughly half of Puig’s rate. While he’s never been a selective hitter, Puig’s approach is undermining his entire offensive game right now.

But the problem with chasing pitcher’s pitches isn’t just that you stop drawing walks. It has that effect too — Puig has drawn just two walks in his last 126 plate appearances, dating back to April 12th — but swinging at pitches on the fringes of the strike zone means that you are much less likely to make quality contact. Puig’s problem isn’t really that he’s swinging through pitches; his contact rates are not that different from what they were a few years ago. He’s not even striking out any more than he used to; his 20.3% K% this year is lower than his 20.7% career mark.

But there has been one huge change in Yasiel Puig’s game this year, and it’s killing his production; he’s turned into a pop-up machine.

Yasiel Puig’s Infield Flies

Season	Plate Appearances	Infield Flies	Popup%
2013	432	9	2.1%
2014	640	11	1.7%
2015	311	7	2.3%
2016	158	13	8.2%

Puig has already set a career high for infield flies in a season, and we’re six weeks in to the year. And as the season has gone on, this has only gotten worse.

12 of Puig’s 13 infield flies have come in the last 30 days. During that stretch, 39% of his fly balls have not even reached the outfield, a staggeringly high total; no other player is over 30% during the same stretch, and the guys who are over 25% are guys like Billy Burns and Didi Gregorius, and they only are that high because they rarely hit the ball in the air.

His popup rate per plate appearance over the last month is a staggering 11.8%, over five times higher than the league average. It’s easy to look at his .203 BABIP over the last month and say there’s some positive regression coming, but when you’re just hitting towering fly balls to the shortstop, that’s not bad luck; that’s bad hitting.

And that’s why Yasiel Puig is batting .180/.196/.300 over the last month. And it’s one of the main reasons the Dodgers offense is scuffling. If the Dodgers are going to contend for the NL title this year, they’re going to have to figure out how to get Puig to stop hitting so many infield flies.

Usually, we expect players to follow a more or less expected curve of decline when they hit their 30s. Obviously everyone is different, but baseball is a young man’s game, and father time comes for us all. Research by Jeff Zimmerman in 2013 showed that hitters don’t even tend to peak nowadays: on average, they perform at a plateau upon reaching the majors, then they decline. Take the wRC+ aging curve for a few different time periods, for instance:

We often talk about a player being “in his prime,” but primes are probably younger than many (or most) people think. In this era, 26 is really the beginning of the average hitter’s offensive decline. Which brings us to Ian Kinsler, who will turn 34 in June: he’s currently posting what would be the highest wRC+ of his career, and Isolated Power marks in line with his best home run-hitting seasons of 2009/2011. That isn’t particularly huge news: plenty of veteran hitters have ~40 game stretches in which they match close to their prime production.

The real news is that Kinsler is currently going beyond that, showing a few underlying indicators that amount to him turning back the clock. He’s also altered his approach, and the combined forces are helping to drive what is currently shaping up to be his best offensive season since he posted a 123 wRC+ with 32 homers in 2011. Kinsler is probably never going to steal 30 bases again (or maybe even 20), but he’s picking up that slack in his production at the plate, especially power-wise.

You don’t need numbers to gain a sense of how Adam Wainwright’s season has started. You just need Adam Wainwright postgame quotes. After his Opening Day start, he wasn’t “anywhere close to being excited,” and called himself “the definition of average.” The next start tied his “career-high-of frustration level” because he was “so upset about the way the ball [was] coming out.” After start number three, he postulated that he’d “made more mistakes these first three games than [he had in] entire seasons.” Start four: “still not great” and “getting tired of losing.” Following his penultimate outing: “The only way I can move on from that is I have to start over. It’s a new season for me from now on.”

That’s a brief rundown of the first eight starts of Adam Wainwright’s 2016 season, in words. I said you didn’t need the numbers, but now you’re going to get them anyway. Through those eight outings, Wainwright ran a 6.80 ERA. The FIP was better, but still a below-average 4.32, and the expected FIP even worse than that. The strikeouts were way down from what we’ve come to expect, the walks were up, and too many balls were being put in the air and leaving the yard. It was the worst stretch of eight games that Wainwright had had in nearly a decade.

Wainwright being 34, and his arm having had the number of surgeries it’s had, a start to a season like that raises some questions. It raises some questions that would be tough to ask to Wainwright’s face. He probably didn’t care about the questions, but he still wanted to give some answers to make the questions stop. Consider his most recent start like the beginning of an answer.

As far as professional athletes go, Wainwright is notably candid. If his stuff isn’t good, even in a win, he’s going to say his stuff wasn’t good. A couple of those negative quotes from the first paragraph came after victories. He doesn’t beat around the bush when it comes to his opinion of how he pitched. The key quote following his most recent outing: “I’m dangerous. You can say I’m dangerous again.”
