For the first few months of this baseball season, everything had been coming up “Belli vs. Yeli.” Of course, this was for good reason.

Since the two sluggers got off to scorching starts, the race for the National League Most Valuable Player award has centered entirely around Cody Bellinger and Christian Yelich. Major League Baseball itself basically even recognized that these two candidates had lapped the field, releasing a commercial prior to the All-Star break featuring Bellinger and Yelich playing a comical game of M-V-P.

But baseball is a long season, and even the surest things are never a given. We might just be witnessing that right now. Nationals third baseman Anthony Rendon is one of baseball’s most underrated players. Despite ranking ninth in WAR since his debut season in 2013, Rendon was finally voted in to his first All-Star game in 2019, though he did not attend. He is a player who Sam Fortier of The Washington Post described as “infamously attention-averse,” and he is also a player who just completed the third-best offensive month of his career. Anthony Rendon demands attention, and in a big way. With his excellent play last month, he might have thrust himself into the mix for the league’s highest individual player honor.

Every year, the Orioles and Nationals play games against one another, though the number actually varies depending on baseball’s rotational interleague schedule. These meetings are referred to as the “Beltway Series,” paying homage to the defining characteristic of the region: traffic on I-495 (the Capital Beltway) and I-695 (the Baltimore Beltway). While I am (mostly) kidding, I still sometimes wonder why there isn’t a better name for this geographical rivalry.

Set to factor in that series is Renato Núñez. The Orioles’ slugging designated hitter is having quite the year. Through games on Wednesday, he has more home runs than Bryce Harper, having hit 28 through his first 488 plate appearances. There’s not much beyond the power, though. He’s slashing .240/.309/.478 with a 103 wRC+, and due to his defensive limitations, he’s been held to just 0.7 WAR.

As we know, the Orioles are not in a position of contention this season, which is exactly why a guy like Renato Núñez can get play in the range of 150 games. All teams look for players with untapped potential. Not all teams, however, can give these players the plate appearances necessary to grow into the productivity that potential suggests. But the Orioles can, and Núñez is the beneficiary.

Núñez’s seemingly odd season had me hunting for a comp. What might a player with this skillset — good power, not a lot of contact, below-average discipline — look like in the future? What can the Orioles expect from Núñez in three, four, or five years?

To answer this question, I downloaded every individual player season with at least 300 plate appearances over the last five years, including 2019. I filtered my search using three conditions: a walk rate between 7-8%, an isolated power above .200, and a batting average between .230 and .250. In my mind, these three results-based constraints accomplish two goals: they limit my search to just a handful individual player seasons and allow me to find players who have similar intrinsic characteristics to Núñez’s.

Because he is still only 20 years old, Juan Soto cannot legally drink in the United States. And yet, despite his recent pubescence, he’s one of baseball’s best hitters. Last week, he became just the third player in major league history to hit 50 home runs before turning 21. He’s drawn comparisons to Miguel Cabrera. He’s even already received some Hall of Fame discussion, assuming he can stay healthy over the course of what ought to be a long career.

In a piece for MLB.com from early August, Mike Petriello noted something interesting about Soto: his consistency.

There are no cold streaks, so there’s no fevered “what’s wrong with Juan Soto?” think pieces, like we’ve done with José Ramírez. There are no wild, Bryce Harper-esque up-and-downs that demand attention. There’s just steady, regular production, the kind of thing that makes Mike Trout so outstanding, and for all of that, sometimes we consider Trout to be boring.

This paragraph from Petriello’s story piqued my interest. Is there any way to examine a player’s consistency? With Soto, I attempted to do so.

At this point, it seems like common knowledge that the sinker has fallen out of favor. We’ve covered that development pretty often here at FanGraphs over the past couple of years. In fact, here’s Jeff Sullivan doing just that in a 2017 piece called, “Baseball is Moving Away From the Sinker:”

“The league got a whole hell of a lot better at hitting the low pitch out of the ballpark. Not exclusively the low pitch, but disproportionately the low pitch. Swings started to gear up for elevating the low sinker. This is something that’s continuing today. Where many of those swings have a vulnerability is up, around the belt. The uppercut swing can have trouble connecting with pitches in the upper half, and those pitches have long gotten swings and misses, anyhow. Sinkers? Sinkers are supposed to be low. They’re not so good at the thigh.”

Since then, homer totals have soared and sinker usage rates have fallen. For those still working with a sinker, it’s often their worst pitch. This is true for Noah Syndergaard, Chris Archer, and even a guy like Aaron Sanchez, who has notably reduced his sinker usage since he was traded to Houston.

That doesn’t mean the sinker is entirely dead. The most obvious example of a guy with an effective one is Zack Britton, who’s riding his sinker to a near-80% ground-ball rate this year. Britton’s a unicorn, but there are still several “normal” pitchers succeeding with sinkers too. Look at the top of the pitch value leaderboard, and you’ll see a decidedly normal pitcher with a good sinker in Julio Teheran. Read the rest of this entry »

During my junior year of high school, I took AP Economics. I found the class to be pretty interesting, and I look forward to continue studying the subject further. But this is a baseball website, and you probably don’t want to be hearing about the classes I took while in high school. However, there was an important concept I learned in AP Economics that applies to a baseball situation I recently discovered. That is, the idea of the trade-off. The trade-off is one of the most basic economic principles, something so basic that it’s subconsciously part of all of our decision-making processes, whether we decide to acknowledge it or not.

One person cannot do everything, and every decision made is at the expense of the other options. There is opportunity cost, and when calculating important decisions, one must weigh the benefits of their choice versus the costs associated with giving other choices up. That’s exactly what Yu Darvish has done this season. Read the rest of this entry »

The other night, I was texting a friend of mine while simultaneously running one of my many queries on Baseball Savant. My “trivia” prompt was pretty simple: “Hitter with the most home runs on pitches outside the zone. Go.” His response was five words. “Javy is the obvious guess.”

Javier Báez was indeed the correct answer. The Cubs’ shortstop, who is known for his free-swinging tendency, has left the yard 28 times this season. Seven of those pitches weren’t even in the strike zone. Only seven hitters this season have at least five out-of-zone homers:

The names on this list are pretty interesting, and as you might expect, there are some similarities between them. Since Báez was the “obvious guess,” it made sense to consider whether most of these players were of a similar free-swinging variety. Generally speaking, they are. Six of the seven names on the list have an O-Swing rate above the league-average mark (31.4%), but what’s fascinating about the rest of this group is that Báez still sticks out, even if he’s not an outlier by the mathematical definition: Read the rest of this entry »

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 »

When it was completed, the Tyler White deal didn’t rock many (if any) boats. It was a minor move: The Dodgers acquired White from the Astros in exchange for Andre Scrubb, a 2019 Rule 5 eligible right-handed pitcher who had most recently been throwing in Double-A.

White has been scuffling of late, but a quick look at his offensive performance from the previous two seasons makes clear why the Dodgers find the first baseman intriguing. White’s bat has been significantly above league-average at times, even if his defensive profile limits his overall value:

In a trade that may or may not dissolve Coldplay, the Braves cushioned their bullpen on Tuesday night by acquiring right-handed reliever Chris Martin. Per The Athletic’s Ken Rosenthal, the Braves obtained Martin from the Rangers in exchange for Triple-A lefty Kolby Allard.

The Braves currently have a fairly large lead over the Nationals atop the NL East, and we have them as the favorite (68.5%) to win the division. To this point, the bullpen has been one of Atlanta’s few weaknesses. Braves relievers have posted a 4.75 FIP and accrued -0.1 WAR this season, the sixth worst total in baseball. Walks have been particularly problematic for this crew, as they’ve allowed an 11% walk rate, the second worst mark in the league. A high strand rate has masked the issue somewhat — the ‘pen has notched a 4.03 ERA — but Atlanta needs reinforcements.

Martin should help. After dominating in the NPB — he posted a 91-to-13 K/BB in 88.1 IP back in 2017 — he’s pitched well since returning stateside the following year. In 2019, he’s been fantastic, and he sports a 3.08 ERA (62 ERA-) in 38 innings. His 26.5% K-BB rate is the 15th-highest among the 182 relievers with at least 30 IP, and he recently went nearly two months without walking a batter. He’s also pitched in plenty of stressful situations: Among Braves relievers, only Luke Jackson has a higher average leverage index this year than Martin. Read the rest of this entry »

Evidently, Nicholas Castellanos doesn’t love playing in Comerica Park.

“This park is a joke,” he told Chris McCosky of The Detroit News on July 21. “It’s to the point where how are we going to be compared to the rest of the people in the league in terms of power numbers, OPS, slugging and all that stuff when we got a yard out here that’s 420 feet straight across center field?”

As we approach the July 31 trade deadline, it appears likely that Castellanos won’t have to call Comerica home for much longer. The Tigers are 30-67, and as MLB.com’s Jon Morosi reported on Wednesday, they are “virtually certain” to trade him by the deadline. But a change of scenery might not be the solution to Castellanos’ problems. Playing the majority of his games in Detroit isn’t why the outfielder has taken a slight step back this season (130 wRC+ in 2018; 114 wRC+ in 2019).

First, let’s dispense with Castellanos’ claim. Here are Castellanos’ 2019 home and road splits:

Those are some pretty drastic splits, but it’s clear that Castellanos is not being hindered by the effects of Comerica Park. The wRC+ split ⁠— which, as we know, adjusts for park factors ⁠— tells the full story. While Castellanos has been a better hitter on the road than at home, it’s not the fault of the ballpark.
