Ian Anderson was one of the better stories of the 2020 season. Entering the year as the No. 3 prospect in the Braves’ system and the No. 44 prospect in all of baseball, he was seen as a future mid-rotation starter who could help quickly. He did just that and more: Added to the rotation in late August, Anderson finished seventh in the NL Rookie of the Year voting despite making just six starts. He put up a 1.95 ERA in those outings, and while the supporting data said he wasn’t the Cy Young-level pitcher that number might suggest, he was still awfully good. He was even better in the postseason, allowing just two runs over 18 innings, striking out 24 and giving up just 11 hits.

Anderson maintained his rookie eligibility entering 2021 and earned the No. 2 ranking in Atlanta’s system (Eric Longenhagen and I discussed putting him at No. 1 ahead of Cristian Pache) and the No. 13 spot in this year’s Top 100 list. He looked like the cornerstone of a young Braves rotation that would help lead them to National League East title contention.

His first start of the year was vintage Anderson (or at least as vintage as you can get for a guy who is still a rookie), as he gave up one run over five innings and struck out seven. His next two were far from it: 11 hits and seven runs allowed over 10.1 innings. Game score is far from a perfect measure, but it’s a simple and quick look at a start, and Anderson’s game scores of 47 and 45 in his last two outings represent the two worst marks of his career. This could be a blip, or there could be some tough luck in there. But a closer look at the data shows that this is more than just a randomly-generated bad run.

When asked to evaluate a pitcher not living up to expectations, these are the first three questions I try to answer.

• Without knowing anything internally, is there anything to worry about in terms of health?
• Has the pitcher changed anything in terms of usage and location?
• Has the pitcher seen his pitch shapes change due to alterations in his mechanics or spin rate?

The Health Question

Toronto Blue Jays General Manager Ross Atkins was the featured guest on episode 918 of FanGraphs Audio, which aired Friday. Here is a transcript of the conversation, lightly edited for clarity.

———

David Laurila: Ross, thanks for coming on FanGraphs Audio.

Ross Atkins: “Thank you for having me on. It’s good to be here with you.”

Laurila: We haven’t seen each other for a few years, but in this crazy pandemic world, I guess that’s maybe not much of a surprise.

Atkins: “I’m surprised we haven’t been on a Zoom call together. It is an interesting existence that we have, seemingly with some light at the end of the tunnel.”

Laurila: I should start by congratulating you for signing a five-year contract extension, which you did last week.

Atkins: “Thank you very much. You know what, it’s nice to reflect on the people that I’ve learned from, and grown from, and have heard from recently — the congratulatory remarks. It’s really exciting for me to think about how fortunate I have been, and I am, to be working with the people I’m with, from Charlie Montoyo and Joe Sheehan and Tony Lacava and Mike Murov. There are so many people that I could list, including some that aren’t here with Toronto anymore.”

Laurila: When I interviewed you two years ago, we talked a lot about process and infrastructure. Today I want to talk more about players, but before we do that, let’s touch on the life of a big-league GM. What does your typical day look like? Read the rest of this entry »

Julio Urías is only 24, but it feels like he’s been in the big leagues for a decade. Called to the majors at only 19 in the 2016 season, he’s been a part of the Dodgers’ future and present for a half-decade. When you start that young, much of your development happens at the major league level. In Urías’ case, that means all kinds of changes. Today, though, I want to focus on one: a curveball that has shape-shifted over time before arriving at a tremendously interesting final form.

When Urías came up, he threw a curve with two-plane break, something between a curve and a slurve. As you can see on our handy Pitch Type Splits, it featured 7.4 inches of horizontal break and only 2.9 inches of drop. In his next three seasons, all injury-affected, he turned the pitch into more of a classic curve — more drop than horizontal movement. 2020 saw a return to his original curveball shape. 2021? Well, it’s weird:

Is it a return to his old form? Is it an acceleration of his old form? Is it something else entirely? Let’s delve too deeply into some gifs and math and find out. Read the rest of this entry »

Even after baseball returned in 2020, a walk around Wrigleyville was anything but normal. The sounds of the Lowery organ, the players’ walkup music, and the fake crowd noise pumping out of the empty ballpark made the streets felt haunted. There were a handful of ballhawks at the corner of Kenmore and Waveland, and a few adventurous souls watched the games from the limited capacity rooftops across the street. But vendors were nowhere to be seen, and most of the nearby pubs and taverns were shuttered. A neighborhood that welcomes more than three million fans annually to the majors’ second oldest park felt like a ghost town.

Ten and a half months later, baseball and fans have returned to Wrigley Field, and so did I. Though I wasn’t entirely sure what to expect as I joined the 25% capacity crowd during the Cubs’ first home stand, I braced myself for that same feeling I experienced so many times walking through the neighborhood in 2020. Instead, I was pleasantly surprised that the sense of desertion had been replaced by one of cautious renewal. Pandemic baseball isn’t the same as the standing-room-only crowds I remember from 2019, but it isn’t the shell we saw last season, either.

When the Marlins beat the Mets on April 10th, most of the post-game focus was on Jacob deGrom. The Mets’ ace had pitched a gem: eight innings, five hits, 14 strikeouts, and no walks, with the only run coming on a towering Jazz Chisholm homer in the second inning. And while the indignation on deGrom’s behalf was not unwarranted, it ironically created a smaller, secondary injustice in its wake, obscuring from view the other stellar pitching performance of the day.

Miami’s starter that afternoon was Trevor Rogers, making his second start of the 2021 season. In his outing, he allowed three hits, walked two, and struck out 10 batters over the course of six scoreless innings – a pitching line that undoubtedly would have been the headline story from the game, were it not for deGrom’s dominant, yet unsupported performance.

But being overlooked is nothing new for Rogers. Skepticism has been a running theme in his career since even before he was drafted, when he was an old-for-his-class high schooler (he graduated at 19) in New Mexico, an area of the country that doesn’t always get the same robust coverage of other parts of the Four Corners region. Could scouts really trust the dominant numbers of a player who was so much older than anyone else on the field?

It is still early in the season, but one of the aspects of hitting that stabilizes relatively quickly is changes to approach. Swings are a more common occurrence, so the sample for these statistics grows faster than those that rely on an accumulation of plate appearances. So who seems to have made some changes in the early going?

To get an idea, I took all players who accumulated 250 plate appearances combined in the 2019 and ’20 seasons (I chose to group these seasons together because of the brevity of the pandemic-shortened campaign), then filtered by those who meet the qualified criteria in 2021. This leaves a sample of 159 hitters; each table includes the top and bottom ten players for each metric.

The Yankees hit bottom this past weekend, not once but multiple times. Projected to be the AL’s best team, they’re instead the worst thus far, with a 5–10 record and a five-game losing streak. On Friday, they played so badly against the Rays that Yankee Stadium fans started hurling baseballs back onto the field, and afterwards, manager Aaron Boone dressed his players down in a closed-door meeting. In terms of outcomes, the stern lecture didn’t help, as the Yankees lost again on Saturday and Sunday, making it the first time they’ve been swept this year.

Friday night’s game saw the Yankees fall behind almost immediately, as opener Nick Nelson surrendered hits to the first three Rays he faced, capped by a two-run double by Brandon Lowe. He escaped without further damage, and Michael King entered to throw three shutout innings, but the Yankees managed just one hit in six innings against Rays starter Michael Wacha. When King departed, errors by Gio Urshela and Rougned Odor helped the Rays roll up four runs against Luis Cessa and then two against Lucas Luetge to pull ahead 8–0. The Yankees finally got on the board via a seventh-inning two-run homer by Giancarlo Stanton, but by the eighth, fans were disgusted enough to throw maybe a dozen baseballs on the field in the general vicinity of the Rays’ outfielders, halting play for a couple of minutes:

Play stoppage because of an excess of baseballs… No really, Yankees fans started throwing baseballs on the field.

We don't get it either!

Welcome to the first week of the FanGraphs Power Rankings. Nearly every major sports site has some form of power rankings; It’s a fun way to think about all 30 teams in baseball and stack them up against each other outside of the rigid structures of leagues and divisions. But where most sites use a panel of experts to build their power rankings — experts who may or may not be simply using their gut feeling to rank teams — I wanted to build an approach to power rankings that was a little more data driven.

My approach basically boils down to taking the three most important components of a team — their offense (wRC+), their starting rotation (SP FIP-), and their bullpen (RP FIP-) — and weighting and adjusting to create an overall team quality metric. I played around with trying to include defense in some form, but adding UZR or DRS or defensive efficiency never really made the team quality metric any more accurate. To test my comprehensive team metric, I used 2020 data to see how it correlated with each team’s win percentage at the halfway mark and their final record. The correlation coefficient at the middle of the season was .68 with an r-squared of .47, and at the end of the season, those marks improved to .80 and .63, respectively.

The final piece of the puzzle was to add in a factor for recent performance while also adjusting for “luck.” Teams with good records should be rewarded, but if they came by those wins in an unsustainable fashion, they shouldn’t receive the full weight of them. Likewise for teams who lost games they might have been expected to win. Put this overall team quality metric together with a team’s adjusted win percentage and you get a solid power ranking formula. And unlike most other sites, I’ll present these power rankings in tiers because the differences between many of these teams, particularly in the middle, isn’t that big. Read the rest of this entry »
