The month of April is now complete and the verdict is in: The in-play home run rate for the 2022 season is down from recent seasons, as shown in Figure 1. Much has already been written about this feature by a variety of authors, including Jim Albert, Rob Arthur, Eno Sarris and Ken Rosenthal, and Bradford Doolittle, Alden Gonzalez, Jesse Rogers and David Schoenfield, and various reasons have been proposed for the relative dearth of home runs. Some argue that the baseball has been deadened, resulting in lower exit velocities and therefore fewer home runs. Others have suggested that the drag on the baseball has increased, perhaps due to higher seams. Yet others have argued that it is the effect of the universal humidor.

In this article, we will address the issue of reduced home run rates and hopefully add more light to the discussion. Specifically, we will examine home run rates during the month of April for the 2018-22 seasons, excepting the ’20 season for which there was no major league baseball in April. Here is our approach.

Before the 2020 season, I wrote a series of articles that looked at how much control batters and pitchers exerted over various outcomes: home runs, strikeouts and walks, fly balls, that kind of thing. I found the conclusions helpful, if mostly as expected: batters have more to say about home runs and line drives, but both sides have input on strikeouts, walks, grounders, and fly balls.

I decided to apply the same methodology – which I’ll detail below – to check on something that I thought I already knew the answer to: do pitchers exert any control over barrel rate, and how much do hitters do the same? Barrels are essentially batted balls hit extremely hard and at dangerous angles; I think they’re a great way of thinking about hard contact.

There’s already been plenty of research on the year-over-year stability of batter barrel rate. There’s been plenty on the fact that pitchers don’t do the same. Here’s a preview of my findings: I didn’t find anything that disputes that. I still think it’s useful confirmation, however, and I’m also pretty proud of the method. Thanks to Tom Tango, there’s even a rough rule of thumb to use if you want to estimate future barrel rates. Without further ado, let’s get to it. Read the rest of this entry »

Brandon Woodruff has been good for years now, but he’s always flown a bit under the radar. In some ways, he can thank his rotation-mates for that: Corbin Burnes has overshadowed him with his ascension to ace status, and Eric Lauer and Freddy Peralta have taken big steps forward of their own. The lack of attention directed Woodruff’s way might also have something to do with him being a little boring. He’s been a polished pitcher with a diverse arsenal since his major league debut in 2017, and nothing has really changed about him since he broke out as a full-time starter in ’19; his performance, velocity, mechanics, and arsenal have all remained consistent. And while having the seventh-best ERA- and fifth-best FIP- in baseball since 2019 unequivocally makes him a great pitcher, he doesn’t seem to have been as big a part of the “best pitcher in baseball” conversations that happen around hypothetical water coolers as those numbers might suggest.

His start to 2022 isn’t helping him much in that regard, with a 5.18 ERA through five outings, though there’s some small-sample funkiness behind that number. Woodruff’s BABIP is 25 points higher than his career average, his LOB rate is an unsustainably low 60%, and his ERA estimators are all around where they typically have been (2.83 FIP/3.25 xFIP/3.07 xERA). I’m not worried about his long-term performance, and regardless, that’s not what this article is about. Instead, I want to focus on Woodruff’s changeup, a pitch that has been anything but boring this season and that was on full display in his most recent start against the Reds:

Most of the talk surrounding Woodruff focuses on his pair of elite, high-velocity, whiff-inducing fastballs, which he throws over 60% of the time. Otherwise, he mixes in a curve and a slider that have both served him well, even if they’ve never quite reached the level of his heaters. Woodruff’s changeup, though, has started to become a serious weapon:

Brandon Marsh has an engaging personality and an innate ability to square up baseballs. He also has untapped potential. Rated as the top prospect in the Los Angeles Angels system prior to last season, the bearded, 24-year-old outfielder is building on a 2021 rookie campaign that saw him put up an 86 wRC+ over 70 games. Logging regular playing time in a dynamic L.A. lineup — this within an MLB-wide environment that is evoking memories of 1968’s “Year of the Pitcher” — Marsh is currently slashing .253/.318/.453 with four home runs and a 127 wRC+.

His offensive profile is more table-setter than bopper. Describing himself as a “gap-to-gap, doubles guy,” Marsh explained that while he’ll run into a ball from time to time, home runs are accidents. Line drives are his goal, which is precisely what the Angels want from him — and have wanted since taking him in the second round of the 2016 draft out of a Buford, Georgia high school.

“They’ve preached for me to keep my hands above the ball, and not be getting underneath and scooping it,” explained Marsh, who is listed at 6-foot-4, 215 pounds. “That type of deal. I’m not a strong, strong guy. I’m tall, but the barrel tends to lag sometimes, so I really need to stay through, and on top of the ball.”

Marsh went on to say that he views himself as a scrappy player whose role is to grind and get on base in front of “a lot of special players.” And while it’s true that he’s not in the same class as teammates such as Mike Trout, Shohei Ohtani, or Anthony Rendon, he nonetheless struck an excessively-humble tone when assessing his own talent level.

Below is an analysis of the prospects in the farm system of the Los Angeles Dodgers. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the second year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the numbered prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here. Read the rest of this entry »

At FanGraphs, our headline WAR number for pitchers is based on FIP. Because of that, and because people enjoy debating and arguing, there’s a yearly refrain that you’ve probably heard. “FanGraphs pitching WAR only considers (X)% of what a pitcher does, how can that be used for value?” No one would dispute that year-one FIP does a better job of estimating year-two ERA than ERA does – or at least, not many people would – but the discussion around whether FIP does a good job of assigning year-one value is alive and well.

One reason for this view is pretty obvious. FIP considers home runs, strikeouts, walks, and hit batters to estimate pitcher production on an ERA scale. Our WAR does some fancy stuff in the background – it treats infield fly balls, which virtually never fall for hits, as strikeouts, and it adjusts for park and league. In the end, though, it’s estimating pitcher value using just three (well, actually four — HBPs always draw the short straw) outcomes. There are a lot of other outcomes in baseball!

In 2021, roughly 39% of plate appearances ended in a homer, strikeout, walk, hit batter, or infield pop up. One thing you could think, in recognition of that fact, is that FIP-based WAR doesn’t consider enough of a pitcher’s production. You wouldn’t use 40% of a hitter’s plate appearances to calculate their WAR, so why do it for pitchers? But that doesn’t actually make sense, as David Appelman pointed out to me recently. Assuming “average results on balls in play” is actually going to be pretty close for every pitcher, by definition. Read the rest of this entry »

Last fall, the Braves won a championship with an outfield that bore no resemblance to the one that they used for the first half of the 2021 season, as circumstances required president of baseball operations Alex Anthopoulos to perform an on-the-fly remake that yielded impressive results. In fact, two of the four outfielders he acquired in trade in July, Eddie Rosario and Jorge Soler, wound up winning MVP honors in the postseason, the former in the NLCS against the Dodges and the latter in the World Series against the Astros. Yet even with two of the principals whose absences necessitated that makeover — Ronald Acuña Jr. and Marcell Ozuna — back in action, this year’s outfield has been a major weakness for a team that has stumbled to an 11-15 start.

We’re still in small-sample territory to be sure — particularly with regards to the individual performances — but through Wednesday, Braves outfielders have hit a combined .191/.261/.331 for a 72 wRC+ in that role, the fifth-lowest mark in the majors. Worse, the team has dipped into the same player pool to cover its designated hitter spot, and they’ve done more sinking than swimming, hitting .171/.235/.226 for a 36 wRC+, the majors’ third-lowest mark. That lack of production has weighed down the team’s entire offense, which ranks 12th in the NL at 3.77 runs per game. Not to be outdone on the other side of the ball, Atlanta’s outfield is tied for last in the majors in both UZR (-6.3) and DRS (-7), though here I’ll remind everyone not to get overly-invested in four week’s worth of defensive metrics; both the outfield and DH spots are second-to-last in the majors in WAR, with -0.8 and -0.9, respectively. In Tuesday’s doubleheader loss to the Mets, their outfielders and DHs went a combined 4-for-28, though Travis Demeritte did drive in their only run that wasn’t accounted for by Matt Olson’s three-run homer, and Acuña collected one of their two extra-base hits outside of Olson’s pair.

Bob Melvin is more than a little familiar with curveballs. Now in his 19th season at the helm of a big-league club, the 60-year-old San Diego Padres manager logged over 2,000 plate appearances and was behind the dish for more than 4,600 innings during his playing career. Seeing action with seven different teams from 1985 to ’94, he caught numerous hurlers whose repertoires included plus benders.

Which pitchers have featured the most-impressive curveballs Melvin caught, attempted to hit, and that he’s viewed from his vantage point in the dugout? Moreover, how do the shapes and velocities of present-day curveballs compare to those of his playing days? Melvin did his best to answer those questions when the Padres visited Pittsburgh’s PNC Park over the weekend.

David Laurila: Who had the best curveball you caught?

Bob Melvin: “I caught many guys with good curveballs, but none were better than Gregg Olson’s. I caught him a lot, and there were times you could literally hear it spinning coming to the plate. It was as 12–6 of a curveball that you could possibly see. He was able to throw it up top if he needed to, for a strike, but the big thing for him was the chase. Nowadays, you’re seeing a little different… a little tighter breaking ball, sometimes at the top of the zone by design. That’s one that’s really tough to lay off, especially if you’re trying to lay off the the high fastball.

“There are certain guys now that pitch strictly north-south. You see the catcher right in the middle of the plate. It’s a high fastball at the top of the zone, and then it’s either a curveball where they’re trying to nip the top or one where they’re trying to get the chase. It’s maybe a little different than back in the day, where there were more sweepers and everything was more down in the zone, unless it was for a first-pitch strike. If you look at Pierce Johnson, with us, his curveball is one of those that you think is going to break a little bit more, but it kind of stays at the top of the zone and you end up taking it for a strike.” Read the rest of this entry »

It would be an understatement to say that Eric Hosmer’s contract with the Padres has generally not worked out. Over the first four years of his eight-year, $144 million deal, the former Royal netted -0.1 WAR in over 2,000 plate appearances, making him one of the majors’ least valuable players to receive substantial playing time in that span. He’s been red-hot in the season’s first few weeks, however, and while he won’t sustain his current .382/.447/.579 clip, the question is whether he can still help a team that was close to unloading him just a month ago.

Hosmer signed with the Padres in February 2018 (right around the time this scribe joined the FanGraphs fold and shortly after noted Hosmer skeptic Dave Cameron — who included the first basemen among his free agent landmines — joined the Padres’ research and development department). In his first four seasons in San Diego, he produced WARs of -0.5, -0.9, 0.7, and 0.6, with the high coming in his 38-game 2020 season, during which he missed time due to a stomach ailment and a fractured left finger but hit .287/.333/.517 (128 wRC+) in 156 PA.

In the context of the first 11 seasons of Hosmer’s career, it would not be unreasonable to call that season a small-sample fluke. From 2011-21, he had nearly 200 38-game stretches across which he slugged .500 or better even if we limit those stretches to the same season and count overlapping ones. Yet he has never slugged .500 or better over a 162-game season, nor has he posted an isolated power of .200 or better. He maxed out on both of those in 2017, when he hit .318/.385/.498 with a .179 ISO while matching his career high in homers (25), a performance that led to the Padres backing up the Brinks truck.

I have some good news about the Yankees. Their collective 120 wRC+ is tied for first among all teams in baseball, an achievement that seems like an amalgamation of skill rather than luck. Case in point: They’re leading the league in every conceivable Statcast metric, including average exit velocity, hard-hit rate, and barrel rate. By hitting baseballs at blistering speeds, the Yankees are turning them into valuable extra-base hits. It’s an ideal process, especially in a season where said hits have been harder to come by.

Next, I have some not-as-good news about the Yankees. It’s something I noticed while looking into Joey Gallo. The lefty slugger recently recorded his first two homers of the season, but his overall batting line is still under water. He’s striking out over 40% of the time, and the little contact he does make hasn’t returned much. You might think this is because Gallo goes after pitches he shouldn’t à la Javier Báez, but last season, he ran one of the best out-of-zone swing rates around. The problem is that even when he’s offered an attractive pitch, he has a gruesome tendency to whiff at it. When Gallo slumps, he doesn’t do so in a manner that’s even the slightest bit flattering.
