In 2017, Christian Yelich finished his last season as a Miami Marlin with a 117 wRC+. That figure, along with the help of his owner-friendly contract, was enough to make him a highly sought-after trade chip — valuable enough for Milwaukee to send the then-No. 13, No. 52, and No. 87 prospects in baseball to acquire his services. Yelich was widely recognized as an excellent baserunner and at least a passable defensive outfielder. But the Brewers were acquiring him for his bat, and they felt his offense from the previous season helped justify the price they were paying.

Fast forward three years, and there are a different set of expectations for Yelich. This winter, he’s coming off a season which he finished with a 112 wRC+, not far from that final season in Miami. But after back-to-back seasons in which he posted a 170 wRC+ and 15.4 WAR — both tops in the National League in that timeframe — and finished in the top two in the MVP voting, that number now looks like a disappointment. There were some positive aspects of his 2020: He walked more than 18% of the time, and while his .225 ISO was below the standard he’d set in his previous two seasons, it still leads all of his Marlins seasons by a substantial margin. But while that helped him maintain an above-average wOBA, they obfuscate a season full of bizarre and unexpected developments for the 28-year-old outfielder.

I’ll admit it: I think about Corbin Burnes way more often than is healthy. Not in a Swimfan way, or anything; his blowup 2019 and standout ’20 are just my favorite example of a pitcher adjusting his pitch mix to match his natural talents, and Burnes has no shortage of talent. His fastball sits in the mid-90s with a naturally robust spin rate, and his slider turns batters into pretzels. He also posted a 6.09 FIP in 2019, driven by allowing 17 home runs in only 49 innings.

What was Burnes’ problem? While his fastball has a lot of spin, it’s not the same kind of spin as your average fastball. His fastball is heavy on gyroscopic spin — the football spin that gives sliders and cutters their signature “dot” — and light on transverse (or “active”) spin, which imparts movement. Of the 601 pitchers who threw at least 250 fastballs in 2019, Burnes’ active spin percentage ranked 585th.

That’s not a death knell for pitchers. The bottom of the list is dotted with sinker-ballers (the two types of fastballs are grouped together), and sinkers are unlike four-seamers in two ways. First, they have less transverse spin in general. Second, they don’t need as much transverse spin, because the effect they produce is a pitch that rises less than a batter expects. As they’re still thrown with backspin, less movement means less rise. Read the rest of this entry »

Here’s a chart I used for a story I wrote last week:

I came across this while writing about Houston Astros left-hander Brooks Raley, whose 2020 season is marked by the dot in yellow. But had you come across this chart in the wild, Raley’s dot wouldn’t be the one that gets your attention. That would be the dot in the upper left, isolated all by itself with baseball’s best whiff rate and one of its lowest exit velocities allowed. If you’re the dot in yellow, it means you had a sneakily good year. If you’re the one off by itself, you’re probably one of the best pitchers in baseball.

That lonesome dot in the corner belongs to Milwaukee Brewers right-hander Devin Williams, who won the National League Rookie of the Year Award on Monday. Among the finalists he defeated for the award were a former third overall pick who reached based 40% of the time in his debut and an out-of-nowhere breakout utility player who helped lead his team to its first playoff appearance in 14 years. From where I sit, the decision shouldn’t have been all that controversial. Read the rest of this entry »

Without a true minor league season on which to fixate, I’ve been spending most of my time watching and evaluating young big leaguers who, because of the truncated season, will still be eligible for prospect lists at the end of the year. From a workflow standpoint, it makes sense for me to prioritize and complete my evaluations of these prospects before my time is divided between theoretical fall instructional ball, which has just gotten underway, and college fall practices and scrimmages, which will have outsized importance this year due to the lack of both meaningful 2020 college stats and summer wood bat league looks because of COVID-19.

I started with the National League East, then completed my look at the American League West, AL East, and Central. Below is my assessment of the , covering players who have appeared in big league games. The results of the changes made to player rankings and evaluations can be found over on The Board, though I try to provide more specific links throughout this post in case readers only care about one team.

The first plate appearance of Game 2 in the Wild Card Series between the Brewers and the Dodgers went like this: a high fastball from Clayton Kershaw, coming in at 92.7 mph. A slider, fouled off by Avisaíl García. Then another slider — a swing and a miss. And then another slider, the best of all of them, for the strikeout.

That first plate appearance set the tone for the rest of the night. Though the 3-0 final score may suggest a close game, in reality, it didn’t feel all that close. Kershaw utterly dominated the Brewers, who, as the broadcast frequently noted, end their season never having cleared the .500 mark. Through eight scoreless innings of work, he struck out 13, allowing just three hits and a walk. It was one of the best postseason performances of his career, and it propels the Dodgers into the NLDS.

For the first four innings of the game, Kershaw and Brewers starter Brandon Woodruff — who hit a first-inning home run off Kershaw in the NLCS two years ago — matched each other blow-for-blow. Kershaw struck out two in the top of the first; Woodruff struck out two in the bottom. Kershaw retired the Brewers in order in the top of the second; Woodruff did the same to the Dodgers in the bottom half of the inning, adding two more strikeouts. In the top of the third, Kershaw pitched around a leadoff single, retiring the next three batters; in the bottom of the third, Woodruff, too, pitched around a single, again striking out two. And in the fourth, both halves of the inning saw all three batters retired, with both pitchers recording two more strikeouts.

Everything was working for Kershaw, whose fastball averaged 91.8 mph over the course of his start. His slider, which he threw 48% of the time, was particularly devastating: It generated 32 swings on 45 pitches, with 20 of those swings being whiffs. Of his eventual 13 strikeouts, 10 were on the slider; nine of those 10 were swinging strikeouts. Woodruff, for his part, also had his pitches working for the first four innings, generating strikeouts on his changeup, slider, and, most often, his fastball, which averaged 96.9 mph.

Thanks to 2020’s 16-team postseason format, the Brewers hold the dubious record of being the first playoff team in baseball history not to spend a single day of the season above the .500 mark. That unfortunate track record continued Wednesday night as the Brewers dropped the opening game of their three-game Wild Card matchup against baseball’s winningest team, the Los Angeles Dodgers. En route to a 4-2 loss, 15 Brewers faced a strike three and a sad trudge back to the dugout.

While the Brewers were never favored entering this series — or in any of its game if you fancy the ZiPS Postseason Odds — a few nasty surprises before first pitch soured their odds even further. The team had originally reshuffled the rotation to try to line up a possible Game 1 start for Corbin Burnes, who put up a 2.04 FIP, 2.4 WAR campaign, qualifying for the ERA title by a single out (he would have finished fourth). Unfortunately for the Brew Crew, an oblique issue scratched Burnes from the Wild Card roster and likely the postseason. Joining Burnes yesterday was Devin Williams, out with an unspecified shoulder injury.

Already down two of their most important pitchers, the Brewers turned to Brent Suter to start Game 1. Their other option was starting Brandon Woodruff on short rest, but coming off a 108-pitch win against the Cardinals (the most pitches he’s thrown in the majors), he was instead held back for Game 2. Suter has extensive experience as a starter, but the Brewers have generally been cautious with him since his return from a 2018 Tommy John surgery, not letting him hit the 60-pitch mark in any start.

My favorite part of the animated series Attack on Titan, in which a race of giants appears out of nowhere and starts feasting on humanity for no apparent reason, is watching the humans try to assess and exploit the giants’ vulnerabilities more quickly than they’re being consumed. It’s analogous to any series against the juggernaut Los Angeles Dodgers, a club coming off a major-league best 43-17 regular season and the presumptive National League favorites to advance to the World Series. Do the Dodgers have a weak spot, a thread on which the limping Milwaukee Brewers can pull and unravel their season? Read the rest of this entry »

We’re a day away from the start of a bizarre, expanded postseason, one with an abnormally large field of teams, a short Wild Card round that makes the better ones unusually vulnerable, and a five-game Division round without an off day. The postseason’s new structure presents one-time advantages and disadvantages that could impact series outcomes. I’ve considered which aspects of roster construction might suit this unique situation (some more familiar than others) to determine which lower-seeded teams are especially strong and are perhaps teed up to make a sneaky deep October run.

For this exercise I’m only considering teams that currently have a winning percentage under .550, since while the Yankees and White Sox are currently seeded fifth and seventh respectively in the American League, I think they’re quite good and relegated to a lower seed purely due to the quality of their divisions. They’re not sleepers, they’re just a lower-seeded contenders. Let’s begin by looking at the obvious criteria.

It’s a tale as old as time, but having starters who can twirl a gem gives you a puncher’s chance in a playoff series. Even if your offense does nothing, a dominant start means you’re, at worst, in a close game with a chance to squeak out a victory despite scoring few runs.

I’m certain this category is the one already most familiar to even casual baseball fans, let alone FanGraphs readers, who can all point at Trevor Bauer, Luis Castillo and Sonny Gray and know the Reds are especially dangerous in this respect. But I wanted to apply some amount of rigor and objectivity to this to make sure I’m not either overrating or overlooking anyone. So I turned to Game Score Version 2. It’s a nice shorthand more than it is a precise, meaningful stat, but while FIP (which I’ve also included in the following table) is a better proxy for overall pitcher quality, I wanted a measure that indicates a pitcher’s capacity to have a dominant and/or elite-level start. As such, in the table is each pitcher’s 2020 FIP, as well as how many times they’ve had a Game Score v2 start of 65 (Strong Starts) or better, and how many they’ve had at 72 (Elite Starts) or better.

Last night, Trevor Bauer made a rather emphatic statement not only on behalf of his team, which is in the playoff hunt, but also for himself in the National League Cy Young race. Bauer pitched eight innings, striking out 12 against one walk and just a single run as the Reds moved above .500 to move into the eighth and final playoff spot heading into today’s action. Meanwhile, though it’s not yet clear if Jacob deGrom or Yu Darvish will get another outing to stake their claims, but Corbin Burnes pitches tonight against the Cardinals. Below you will find the NL WAR leaders among pitchers through last night’s contests:

At the beginning of last season, my colleague Ben Clemens examined Milwaukee Brewers right-hander Corbin Burnes in something of a study into what pitchers can control, and which skills can be demonstrated fastest. Burnes had made just one start at the time, striking out 12 batters against one walk in five innings, while also allowing six hits including three homers. More illustrative than those results, however, were Burnes’ elite spin rates. Spin doesn’t take several outings to stabilize, and it isn’t something a pitcher flukes in and out of. Like velocity or foot speed, it is something one either possesses or doesn’t. Burnes has it. Ben’s a smart guy, so he hypothesized that it was likely those spin rates would help keep Burnes’ strikeout numbers high in future appearances, while his home run rates should taper off. Because really, who has that kind of stuff and still gives up three homers a game?

Well, in Burnes’ next start after that piece ran, he gave up three home runs again. In the start after that, he gave up another three. And in the start after that, he gave up two more. Then he moved to the bullpen, where he was fine for a couple of weeks — until Atlanta hammered three dingers off of him in just two-thirds of an inning. Burnes finished the season with 12.86 strikeouts per nine, and 3.12 homers allowed per nine. When opponents hit fly balls against him, 38.6% left the yard — the highest single-season HR/FB rate on record for anyone with at least 40 innings pitched. When he kept the ball in play, he was also historically unlucky; his opponents’ .414 BABIP was the fourth-highest on record. Burnes can say more about himself with a single pitch than just about anyone else, and yet his entire 2019 season only served as an example of all that can happen that’s outside a pitcher’s control.

Somehow, Burnes is having that kind of season again in 2020 — just in the opposite direction. Last year, he allowed 70 hits and 17 home runs in 49 innings. This year, he’s thrown 45.1 innings, and has allowed 22 hits and one home run. His 2.9% HR/FB rate is the second-lowest of any qualified starter, and his .233 BABIP is seventh-lowest. In a single year, he has transformed from, statistically speaking, possibly the unluckiest pitcher we’ve ever seen into the one of the luckiest of this season. What does that mean for Burnes, and for the way we talk about luck in baseball? Read the rest of this entry »
