There’s an easy complaint that baseball fans the world over lob at analytical, number-driven sorts like me. “Hey nerd,” it starts. “Baseball is played on the field, and your numbers can’t measure heart and smarts.” The nerd part is constant, the things the numbers can’t measure varied. That complaint misses the mark, because no one loves baseball for the numbers without also loving it for the viewing pleasure. Appreciating the statistics doesn’t have to detract from how fun it is to watch a pickle or to see a beautifully executed tag.

While that complaint is mostly off the mark, it does get one thing about statistics right. There are some things that you simply don’t need a big sample size to know. Want to know if a player is adept at hitting the ball the other way with two strikes and runners in scoring position? You’ll need a sample that could blot out the sun. Want to know if a pitcher throws 100 mph? One or two pitches will do. Not everything needs to be regressed to the mean, and not everything needs thousands of data points to be valid.

Here’s merely one example: Emmanuel Clase has thrown 38 pitches in the majors. All of them have been this week. He has one strikeout, one walk, and nine batters faced. We’re nowhere near any of these numbers stabilizing, nowhere near his strikeout rate or walk rate or BABIP being meaningful. Despite all that, I can say this with certainty: Emmanuel Clase has a chance to be one of the best relievers in baseball, and he might be the most uncomfortable at-bat in the majors already.

Why? Well, Clase is a two-pitch reliever — 80% fastballs and 20% sliders. Look at pitch classifications, and the fastball usually turns up as a four-seamer. He averages 99 mph with it and has topped out at around 102 in the minors, which is already special enough, but that’s not even the interesting part. You see, it’s not a four-seam fastball, at least not in the way you think of that pitch. It’s not a fading, rising missile that explodes through the top of the strike zone. No, Clase throws a cutter, a 100-mile-an-hour optical illusion that bores in on the bats of lefties and the very souls of righties. One cutter was all I needed to see to know that I’m going to enjoy watching Clase for as long as he pitches. Read the rest of this entry »

Last Saturday night against the Padres in Los Angeles, five days past his 25th birthday, Walker Buehler authored the most dominant start of his young career. With a fastball that touched 99 mph and a slider and cutter that continually befuddled hitters, the Dodgers righty faced 31 batters, struck out 15 of them, walked none, and yielded just five hits. Only one of those hits was of consequence, namely Manuel Margot’s eighth-inning pinch-homer, which kept Buehler from throwing a complete-game shutout; he and the Dodgers had to settle for a 4-1 win. Even allowing for the fact that the Padres own the majors’ highest strikeout rate (26.0%) and weren’t fielding a modern day Murderer’s Row, Buehler’s performance was a thing to behold.

So, behold!

While the major league strikeout rate is again at an all-time high (22.8%), Buehler’s start was just the sixth of the season in which a pitcher struck out 15 batters. He’s the only pitcher with multiple 15-K games, as he whiffed 16 but allowed two solo homers (from among just three hits) against the Rockies on June 21; he didn’t need more than 111 pitches in either start. Here’s the complete set: Read the rest of this entry »

Before the season started, expectations for Jack Flaherty were pretty high. After posting a 3.86 FIP, a 3.34 ERA, and 2.4 WAR in 151 innings in his first full season in 2018, projections expected Flaherty to be even better with a 3.74 FIP. After a rough start in Seattle on July 2 in which Flaherty failed to make it out of the fifth inning by walking four and giving up four runs including a homer, the season looked to be a step back rather than a step forward. With a 4.82 FIP and 4.90 ERA on the year, Flaherty’s stats represented a half season of below-average numbers.

Since then, he’s been one of the best pitchers in baseball.

As for what happened, here’s a brief comparison of his numbers over the last month versus the first three months of the season.

We can see from the BABIP and LOB% that there’s probably some luck going on here with the sub-1.00 ERA, and even if there’s a little bit of luck on the home run rate, his 2.20 FIP wouldn’t be impacted that much. A decrease in homers might be luck evening out, but a big increase in strikeouts while seeing the walks go down shows that there’s clearly more than chance that’s pushing Flaherty to great results. It’s not the opponents either, as two of his six starts have come against the two best offenses in the game in the Astros and Dodgers, with the Cubs boasting a top-six offense as well. The biggest change is more fully embracing his best pitch, the slider. Read the rest of this entry »

It looked as though Gleyber Torres’ number was up. One by one, from late March onward, the Yankees had sent every member of their expected 2019 starting lineup to the injured list at some point except Torres. From Didi Gregorius’ ulnar collateral ligament and Aaron Hicks’ back on March 28, through Miguel Andújar’s labrum, Giancarlo Stanton’s biceps, Gary Sánchez’s calf, Aaron Judge’s oblique, Luke Voit’s abdominal muscle, and Brett Gardner’s knee, injuries caused all of them to drop like flies. Multiple waves of reinforcements, the likes of Troy Tulowitzki, Clint Frazier, Kendrys Morales, Cameron Maybin, and Edwin Encarnación, met similar fates. When Torres left Tuesday night’s game against the Orioles in the middle of the third inning due to what was described as “core pain” — his second early departure in three nights — and returned to New York for testing, an IL stint appeared to be a foregone conclusion.

The Yankees had even gone so far as to summon infielder Thairo Estrada from Triple-A Scranton/Wilkes-Barre to Baltimore while Torres received an MRI, but he wasn’t needed. Via manager Aaron Boone, “[Torres] went through a battery of tests today and everything checked out OK. MRIs, testing again for a sports hernia, any strains, and everything turned out to be negative. Looking at him as day to day. I think he’s upbeat, he feels good, so he’s on his way back now, and he’ll travel with us to Toronto.”

The 22-year-old Torres has built upon a strong 2018 rookie campaign that itself included a 20-day stint on the disabled list for a right hip strain. His numbers — .281/.347/.505 with 23 homers, a 120 wRC+, and 2.3 WAR — are a near carbon copy of last year’s; he’s one homer shy of his total and his wRC+ is identical, while his WAR is already higher in 18 fewer games. He made the AL All-Star team for the second straight season, and even with a modest slump to start the second half, his line conceals slight improvements in his strikeout and walk rates as well as his defense. In the time between Tulowitzki’s calf strain and Gregorious’ return from Tommy John surgery, he more than held his own in a 64-game stint covering shortstop.

Torres has played a team-high 105 of the Yankees’ 114 games. He survived a couple of smaller injury scares, missing four games in May due to a bruised right elbow after being hit by a pitch and a couple in early June due to a sore left shoulder, the origin of which was unclear. He left Sunday night’s win over the Red Sox in the eighth inning due to the onset of this “core issue.” Via Yahoo Sports’ Mike Mazzeo, earlier in the game he had appeared to be running to first base with some amount of discomfort. He went to the hospital for tests, but according to the New York Daily News’ Kristie Ackert, Torres said that doctors had ruled out a sports hernia via ultrasound. He played all nine innings of Monday’s game against the Orioles in Baltimore, but he departed mid-game on Tuesday night, just after striking out in his 11th straight plate appearance without a hit.

Jay Jaffe: Hello, sports fans! Welcome to another edition of my Thursday chat. In 24 hours, I’ll be arriving in Boston for this week’s Saberseminar along with several of my colleagues, and if you’re in the area tomorrow night, we’d like you to join us for some snacks, adult beverages, and baseball chatter https://blogs.fangraphs.com/instagraphs/fangraphs-saberseminar-boston-…

Jay Jaffe: Now, on with the show…

Jay Jaffe: I don’t think one has to go strictly by a WAR leaderboard to choose an MVP. First off, we have multiple versions of WAR that have different inputs, both with regards to pitching models and defensive metrics, and each of them can help illuminate different aspects of what we’re trying to reward.

12:07

Jay Jaffe: Second, we can certainly bring some other stats and context there. WPA and clutch metrics can be part of the discussion. Absences due to injury (that player may have missed some games but been better on a prorated basis as far as WAR is concerned, or he may have come up big while a key teammate was injured), changes in role, particularly strong performances against a division rival or down the stretch… The bottom line is that we don’t need to be slaves to the decimals. The WAR leader is still gonna be the WAR leader whether or not he gets the hardware.

As Ben Clemens succinctly put it on Tuesday, “Here come the Mets.” If you have read Ben’s piece, I’m not going to bore you with the same details. If you haven’t, you should go do so.

In short, the Mets were bad, and now they’re good. But even with this current stretch of newfound dominance, their seemingly high-octane offseason remains a mixed bag. Edwin Díaz and Robinson Canó still haven’t lived up to their high expectations after being brought in from Seattle, Jed Lowrie hasn’t played a single game due to a calf injury, and Jeurys Familia won’t stop walking hitters. For all the talk about how good the Mets’ offseason was, it’s still not those players who are leading the charge. That is, save for this one obvious exception:

In a sense, J.D. Davis has been the Mets’ savior. As they’ve heated up, he has not only been one of their best offensive players but also one of the best bats in baseball. In the 30-day period between July 8 and August 6 — as the Mets’ playoff odds have increased by 35 points — Davis has slashed .385/.468/.615 in 77 plate appearances. His 187 wRC+ during this time is the seventh-highest in baseball. His defense has limited his overall value a touch, but even still, his 0.9 WAR in this time period ranks 32nd out of 181 qualified position players. Read the rest of this entry »

The other day I wrote about Shin-Soo Choo and the way he’s hitting the ball really hard despite being a 37-year-old who has never garnered much of a reputation as a power hitter. In that piece, I included a chart that showed Choo was having the second-best season in terms of hard-hit percentage by a player 35 years of age or older since we started gathering such data in 2002. Choo was deserving of the digital ink used on him, but as impressed as I was with his placement on that chart, the most remarkable player listed was the one directly above him. The hard-hit rate that Choo had put together that ranked second on that list was 46.7%. No. 1 on that list was 2019 Nelson Cruz, whose hard contact rate currently rests at a whopping 55%. He’s 39 years old, and he’s hitting the ball hard more often than anyone else in baseball. He also just wrapped up one of the hottest two-week stretches you’ll ever see.

On the morning of July 22nd, Cruz was in the middle of yet another strong season at the plate. His slash line was .270/.364/.543 with 19 homers in 71 games. Even as a designated hitter, that’ll play on just about any team. Then all hell broke loose.

Look, it is usually best not to fuss too much over a hot streak that is over a sample size this small. The baseball season is long, and because of that, there will be many, many players who throw together a torrid two-week stretch or two. In that table, the next-best players in those categories ranged from Anthony Rendon to Andrew Benintendi to Mike Tauchman. Those players should all feel very happy and proud of the way they’ve been playing baseball, but unless your name is Mike Trout, there is a very good chance that an amazing two-week stretch of baseball will not be followed with another two-week stretch that is just as amazing. This is just the way the game works, and there’s no use in getting too excited over what is only around 50 plate appearances, about 1/12th of your season or less. Read the rest of this entry »

For major league pitchers, the end always feels depressingly close at hand. In a game increasingly dominated by power and velocity, losing a tick can be the difference between sneaking a fastball past someone and watching a home run trot. Throw in elbow injuries, blisters, and hitters obsessively watching video looking for any exploitable edge, and it’s a miracle that any pitchers can sustain success.

Clayton Kershaw is no exception to this pattern. He may be the greatest pitcher of the 21st century, but that doesn’t give him special immunity from velocity loss or a license to avoid injury. Gone are the days of Kershaw posting sub-2 ERAs regularly. That’s partially due to the changing offensive environment, to be sure, but it’s also a reflection of the fact that Kershaw is aging. His strikeout rate fell last year to the lowest rate since his rookie season, a pedestrian 23.9%. He made less than 30 starts for a third straight season. His fastball velocity declined 1.5 mph. Age comes for everyone, or so it seems.

When Kershaw returned from a season-opening IL stint, he did so with old-man wiles. His velocity was down another tick, now approaching 90 mph. As Ben Lindbergh ably chronicled, Kershaw’s plan was to stick with what worked in 2018 and survive on sliders and first-pitch strikes. He became perhaps the most extreme pitcher in baseball, piping in first strikes nearly three-quarters of the time and afterward departing the strike zone entirely. He accomplished that trick by throwing his fastball 61% of the time to open at-bats and only 33% of the time after that.

However, even these extreme changes couldn’t hide the fact that Kershaw was slipping. At roughly the midpoint of the season, July 1st, Kershaw was 36th in WAR among pitchers, sandwiched between Kyle Gibson and Sonny Gray. He was marginally better, 24th, by RA9-WAR, but even there, it was weird seeing Kershaw’s name next to Yonny Chirinos and Zach Eflin. Some of this came from a limited workload, but his 3.23 ERA and 3.76 FIP told the same story. It wasn’t just the ball, either: his 77 ERA- and 89 FIP- were his highest since his rookie year, and his 22.7% strikeout rate was down even from last year’s low level. Read the rest of this entry »
