May was a successful month for the Tigers, a franchise which in recent years has been lacking in happily remembered calendar pages. Detroit’s .577 winning percentage in May (15–11) is its best full month since a .615 mark (16–10) all the way back in July 2016. And while it would be a stretch to say that everything has been coming up bengal, given that the team’s run differential is still slightly in the negative for the month, the bleakness of the AL Central has allowed the Tigers to come within a game of the division lead. Even Spencer Torkelson, whose bat disappeared in 2022, has been playing better baseball, putting up a 119 wRC+ in May. Unfortunately, fate wasn’t even kind enough to give Detroit the whole month; a couple of days before the calendar flip, injuries to Eduardo Rodriguez and Riley Greene have ended May on a decidedly sour note.

These Tigers certainly aren’t strangers to injury. Every team faces injuries sooner or later, but Detroit managed to win in May despite an entire rotation’s worth of promising pitchers — Tarik Skubal, Matt Manning, Spencer Turnbull, Casey Mize, and Beau Brieske — out with injuries. The contributions of Rodriguez and Greene had a lot to do with that. The former’s hot April start continued in May with a 2.03 ERA/2.61 FIP over five outings; the latter hit a star-level .365/.435/.573 for the month. That came crashing down on Tuesday with two bits of very unwelcome news. Read the rest of this entry »

Matt Olson is striking out a lot. Exactly 30% of the time, to be precise. His swinging strike rate has never been higher. He’s only posted a lower contact rate once, in his disastrous 2020 campaign. Obviously, then, you know how he’s doing this year: incredibly well. His 140 wRC+ is the second-best mark of his career. Clearly, something interesting is going on, so let’s take a look at what it might be.

Honestly, the strikeouts are nothing new for Olson. His career 24.1% strikeout rate isn’t ideal for a top-tier hitter, particularly one with limited defensive value. It puts a lot of pressure on the rest of his game. You can succeed while striking out a lot, but you have to do a lot of other things well to strike out a quarter of the time and be a great hitter.

Throughout his career, Olson has mostly done that. Take his 2019 season, when he struck out 25.2% of the time. He hit for a ton of power – even playing in the cavernous Coliseum, his ISO was in the top 15 in the majors – and walked enough to post a reasonable OBP. But you can see the downside easily. Consider 2022, for example. Olson again struck out roughly a quarter of the time – 24.3% – and walked a similar amount. He again posted a top-15 ISO; a lower number, to be sure, because 2022 had far fewer homers than 2019. But he ran a .274 BABIP, and that along with the fact that he was playing in a better offensive environment but putting up similar numbers meant he was only 20% above average rather than 35% above average.

Seen next to each other, these two seasons explain the chief worry with Olson. Without much change in his underlying skills, he was only 20% above average offensively last year:

That’s still a nice player, but a first baseman with that kind of batting line is hardly an All-Star. It was the 13th-best batting line for a first baseman in the majors, hardly better than his replacement in Oakland, Seth Brown. That’s the kind of tightrope that a player with Olson’s skill set is always walking; a slight dip in power or BABIP can be the difference between average and excellent. Read the rest of this entry »

Aaron Judge is at it again. On Tuesday night in Seattle, the reigning AL MVP and home run king clubbed a towering solo shot off Darren McCaughan to aid the Yankees’ 10–2 win over the Mariners and to continue his latest rampage. It was his fourth homer in three days, his 12th in his past 16 games, and his AL-leading 18th overall. With that, he’s matched his total through the end of May last year, doing so in 46 games, one fewer than in 2022, though the Yankees have played 57 games, leaving him still behind the full-season pace he set en route to an AL-record 62 homers.

Even with this binge, Judge doesn’t lead the majors in homers. Hell, he doesn’t even lead New York City in homers. That honor belongs to Pete Alonso, who’s hit 20. Though he hasn’t homered since Saturday against the Rockies, the Mets first baseman has hit 14 since May 9, the day Judge came off the injured list after missing 10 games due to a minor hip problem. Here’s Saturday’s homer, which came at the expense of Chase Anderson:

Now that we’ve enjoyed some dingers, it’s only fair to mention that this article isn’t really about either of the Empire State’s sluggers so much as it is the conditions under which they’re positioning themselves for runs at 50-homer seasons — again. Recall that Judge set a rookie record with 52 in 2017, only to be topped by Alonso with 53 two years later. Balls aren’t flying out of the yard at the pace they did in either of those seasons, which happen to be the two highest full seasons on record; in 2017, teams bashed 1.26 homers per game, and in 2019, they upped that rate to a stratospheric 1.39 per game. This year, teams are averaging 1.15 homers per game, the seventh-highest rate on record (or sixth-highest, if you exclude the pandemic-shortened 2020 season). You have to carry the calculations out to a third decimal to place it properly:

You know what’s important? Pitches. Almost all of the big stuff that happens on a baseball diamond starts with the pitcher pitching. Even Babe Ruth never once hit a home run without somebody throwing a pitch first.

Now that we’re more than a quarter of the way through the 2023 season, let’s take a look at the pitches. Specifically, we’re going to take a look at long-term trends, and talk about the ways in which this year has (or hasn’t) followed them. As such, I need you to prepare yourself for a whole lot of line graphs. In fact, just to drive home how many line graphs are in this article, here’s a bar graph:

Last week we ran 26 regular articles, in addition to chats, podcasts, prospect lists, and power rankings. We’re pretty busy. There were fewer line graphs in those 26 articles than there are in the next couple thousand words.

You know what? Seeing as the only bar graph in the past week is the one you just saw, maybe we should also give a quick update to our little guy.

Much better. Read the rest of this entry »

This is a big year for the MLB rulebook. After decades of tiny incremental changes, the league made three huge ones in 2023. They instituted a pitch timer, changed the size of the bases, and restricted defensive positioning for the first time in modern history. But how have these new rules changed how the game looks on the field? I broke down each one to find out.

Games Are Shorter

The biggest change to the game this year was the introduction of a pitch timer, and it’s had a huge impact on game length. Per Baseball Reference, the average nine-inning game has lasted two hours and 37 minutes this year, down from three hours and three minutes last year. You have to go back to 1985 to find a shorter average game length.

Despite that drastic change, the amount of action in a game hasn’t changed much. Plate appearances per game are roughly unchanged: there are 75.6 this year, quite close to the 76.4 average in the 21st century. Pitcher per plate appearance are stable: 3.9 this year, 3.9 for the last 10 years on average.

The difference is all pace. Per Statcast, pitchers are taking three fewer seconds to throw with the bases empty and 4.5 fewer seconds to throw with a runner on base. The bases-empty change is welcome but only gets us back to the numbers that prevailed 15 years ago or so. The change with runners on base is far more important; we’ve likely never seen a faster pace when pitchers are holding runners, though the data only goes back to 2010. Read the rest of this entry »

The drama of a superlative catch at a crucial point in a game is one of baseball’s great narrative moments. A ball is struck and everyone – fans, baserunners, sprinting outfielders – holds their breath for a few seconds waiting for it to hit either leather or grass, sending those baserunners and swinging the game in one direction or the other. It’s baseball’s version of a three-pointer heading towards rim or net, or a wide receiver and a cornerback extending for the same airborne pass – a moment of suspense in the most literal sense of the term, during which the only thing drawing us closer to a conclusion is gravity.

Now, because there’s nothing baseball fans love more than taking a beautiful moment of athleticism, emotion, and aesthetics and distilling it into numbers, I’ve been mulling how to appropriately credit an outfielder for a play like this – particularly with respect to how it impacts the game in that moment. We have a pretty good measure for what a batted ball is worth if it falls in for a hit or is caught for an out, adding to one team’s chances of winning depending on the score and base-out situation – Win Probability Added. But what about when the ball’s in the air and it’s up to the outfielder to track it down? How much credit (or blame) is owed to the outfielder? How do we measure how much the outfielder’s defense itself swung the game? Read the rest of this entry »

Everton-Bournemouth stands out among today’s Premier League matchups, as the former will secure a return to England’s elite division with a win (they could also survive with a loss or a draw, but only if both Leeds and Leicester City likewise fail to win). Everton FC, which is located in Liverpool, was last relegated below the top flight in 1951.

As most EPL fans are aware, Everton’s home grounds, Goodison Park, are located less than a mile from Anfield, the historic home of Liverpool FC. They also know that the principal owner of Everton’s longtime arch rival is John Henry, whose Fenway Sports Group purchased the more-ballyhooed of the two clubs in 2010.

According to a new book by Bruce Schoenfeld, the acquisition happened only after initial reluctance from FSG’s ultimate decision-maker. As chronicled in Game of Edges: The Analytics Revolution and the Future of Professional Sports, Henry proclaimed the following during a business meeting held to assess the possible purchase:

I’m going to say this bluntly because it’s something that most should agree with: Harrison Bader’s defense in center field is special. Unfortunately for Bader and baseball fans, he has never totaled above 430 plate appearances in a single season, so we’ve never had the privilege to see him run around the outfield for a traditional full season and rack up defensive value. But even with this limitation, he’s still at or near the top of just about every aggregated defensive metric leaderboard for the last few seasons. If you watch him roam the outfield — and I mean really watch him — you realize that this is a player who does everything correctly out there and has an unflappable baseball IQ. If you could write a script on how to be the perfect outfielder, all you would need to say is “be Bader.”

Let’s start by addressing where Bader ranks next to his peers this season in terms of defensive metrics. I’m only going to focus on Outs Above Average (OAA) for this piece. Defensive metrics are a great starting point to a conversation like this, but they are a complement to video analysis that will show us the details of a player’s fundamentals and decision making.

Here are the leading outfielders in terms of OAA this season:

One of these is not like the others! Given that OAA is a counting stat, a player with at least 16 fewer games played (usually more) should not be on this list, but Bader only trails Robert this season in OAA, and that is mainly due to his Success Rate Added. That gives some more insight into how valuable he has been in his limited sample this year. Read the rest of this entry »

It may not have ended the slump he’s fallen into since mid-April, but Trea Turner picked a very good time to snap out of a 2-for-20 skid that began last weekend. On Wednesday afternoon against the Diamondbacks, the Phillies were trailing, 5–3, and down to their final out, in danger not only of being swept in the three-game series but also of losing for the eighth time in 10 games. Then José Ruiz hung a curveball that Turner didn’t miss, pounding it for a game-tying two-run homer. The Phillies won in 10 innings, but whether this the start of a turnaround for Turner — who, like Manny Machado, is off to a rough start on his new $300 million contract — remains to be seen.

The homer was Turner’s fifth of the year and his first since May 6. Even with it and Thursday’s subsequent 0-for-5 against the Braves, his offensive numbers look a whole lot more like what the Phillies got from their shortstops (Didi Gregorius, Bryson Stott, Johan Camargo, and Edmundo Sosa) last year than what Turner did with the Dodgers:

Turner has been frank about his struggles. After Monday’s loss to the Diamondbacks, he told reporters, “I’m honest with myself, I’ve sucked.” While that may be overstating the case a bit, he hasn’t offered anything close to his superstar-level play of the past two seasons, and only through respectable (if small sample) defensive metrics at shortstop (1.6 UZR, 1 OAA, -2 DRS) is he above replacement level. Using our UZR/OAA inputs, his 0.6 WAR prorates to 2.0 over a full season — more or less average — but using DRS, his 0.3 bWAR prorates to just 1.0 WAR, or decidedly below average.

It seems like all of our coverage of the 2023 Diamondbacks here at FanGraphs has focused on the pitching, and it’s not hard to see why. Zac Gallen has looked phenomenal (at times historically so), Madison Bumgarner was abominable (eventually too abominable to roster), and the D-backs have given some intriguing young arms the chance to prove their worth in the big league rotation.

Yet all that being so, the real story of the 2023 Diamondbacks has been the offense. They lead the National League in hitting and rank third with 257 runs scored. They’re fourth in OBP, fourth in slugging percentage, and fifth in wRC+. By and large, the pitching staff has performed as expected – Gallen good, MadBum bad, everyone else somewhere in between – but the offense has been more potent than anyone could have envisioned.

It’s been a team effort in Arizona; among the nine Diamondbacks hitters with at least 100 PA, seven have been above-average at the plate. Corbin Carroll is off to the races. Lourdes Gurriel Jr. has taken a massive step forward. Ketel Marte and Christian Walker have been predictably solid, while Gabriel Moreno and Pavin Smith are holding their own. Leading the way, however, has been none other than Geraldo Perdomo, who is pacing the club in OBP, wRC+, and WAR. What? Read the rest of this entry »
