As you all probably know, at the start of every season, the FanGraphs staff puts together our bold predictions for the coming year. Each is, to varying degrees, plausible but unlikely, which is what makes it such a fun exercise. Anyway, entering the 2025 season, my bold prediction was: Corbin Carroll will become the fifth-ever 20/20/20/20 player — 20 doubles, 20 triples, 20 home runs, and 20 stolen bases in a single season — joining Frank Schulte in 1911, Willie Mays in 1957, and Curtis Granderson and Jimmy Rollins, who both did it in 2007. Carroll ultimately fell just three triples short of the threshold, while tallying 32 doubles, 31 homers, and 32 steals.

I decided not to run it back this year, figuring that wouldn’t be as fun, though I am very much still rooting for it to happen. The 20/20/20/20 Club is one of the most exclusive baseball has to offer. Pulling it off requires a precise combination of power, speed and instincts, and it has to happen at the exact right moment in a player’s career. As I wrote in my bold prediction: “A player needs to have enough pop to hit 20 homers, but not so much that the majority of his extra-base hits land in the seats. He also needs the speed to steal bases and stretch singles into doubles and doubles into triples. His instincts must be sharp, so he can know when to attempt the extra base without running into outs.”

Last Saturday, when I saw that Carroll had doubled and tripled in a 10-3 Diamondbacks win over the Braves, I pulled up his player page to check on his progress. He was up to 26 doubles, 15 triples, 18 homers, and 16 steals. He stole a base the next day, and after going without an extra-base hit in Arizona’s three-game series against the Red Sox, Carroll entered play Friday at 26 doubles, 15 triples, 18 homers, and 17 steals with 34 games left to play. This prompted my own question for this week’s mailbag, which I will get to momentarily. We’ll also answer your questions on the worst player to ever hit three home runs in a game, the biggest drop-off for a player in the season after finishing second in the MVP voting, and teams missing the playoffs despite leading the league in run differential.

I made my first trip to Oracle Park earlier this week to catch the final two games of a three-game set between the Giants and Astros. I was in San Francisco reporting a different story, but I was eager talk about Yordan Alvarez with his teammates, his opponents, and pretty much anybody else who was interested. I’ve long compared him to Willie McCovey because of his overwhelming physical stature and profile at the plate — it helps that Alvarez, like McCovey, also bats left-handed and wears no. 44 — and I considered myself fortunate to get to see the Astros DH play in San Francisco. I hoped I’d get to witness him launch one into McCovey Cove. That didn’t happen, but it was still fun to watch him during what’s turning into a career year.

One of the players I talked to about Alvarez was Houston outfielder Taylor Trammell. His response, to a question about what makes Alvarez so good, is worth sharing. “He is the most efficient player I’ve ever seen,” Trammell said. “He does exactly what he needs to do to get himself ready to play well, and then does nothing more. His preparation seems so effortless because he has so much confidence in his routine. He’s shrunken it all into a box.” Trammell also bats left-handed, yet he said he can’t study Alvarez to figure out what to do in the box because “pitchers throw differently to him. They throw him the pitches they don’t throw to anyone else just to try something to get him out.” He said Alvarez sees changeups from pitchers that he didn’t even know had changeups, and while that might’ve been a slight exaggeration, it worked to explain the helplessness that opposing pitchers must feel when Alvarez is in the box.

That’s the last we’ll discuss Alvarez here today, but if you want to read more about his MVP-worthy season, I’d encourage you to check out Dan Szymborski’s post from Monday breaking down Alvarez’s odds of winning the American League Triple Crown. Instead, in this week’s mailbag, we’re answering your questions about a pair of Cardinals pitchers who are greatly outperforming their peripherals, whether strong plate discipline translates to successful ABS challenges, the final franchise to (maybe) register a 100-loss season, and more.

On Friday, the Boston Globe ran a story by Red Sox beat writer Alex Speier on the concept of momentum. I can hear the collective groans of our Members now. Haven’t we gone over this enough? We’ve already established that there’s no such thing as momentum! Or, if there is, its effect is minimal. Our readers would be the first to point out that the month-and-a-half long surge up in Boston is mostly a matter of a talented, drastically underperforming Sox team experiencing some serious positive regression, bringing its overall record back up to about where we expected it to be all along. I get that, of course. We cannot conclusively prove the effect of momentum in baseball — and it’s not for lack of trying — and so therefore cannot definitively say that it exists. Yet when it comes to the Big Mo, a palpable feeling rather than a tangible metric, I tend to subscribe to what I call the Robert Graysmith Theory: Just because you can’t prove it, doesn’t mean it isn’t true.

What’s interesting about Speier’s piece is that he, along with Globe staffers Julian Benbow and Daigo Fujiwara-Smith, looked for data to support the impact of momentum on winning and losing streaks. Speier, an analytically savvy writer, said in his Bluesky post sharing the story that he “was skeptical” that their search would lead to anything. Instead, he was astonished to learn that, as he writes in the story, “A Globe analysis of Retrosheet data that includes the outcome of every MLB game from 1901 through 2025 revealed a striking pattern: The longer a winning streak lasts, the higher a team’s winning percentage in the next game.” The inverse is true for losing streaks. Speier mentions several factors unrelated to momentum that help to explain why “baseball streaks tend to be somewhat self-sustaining,” most notably that team quality probably plays a major role in enduring stretches of winning or losing. That alone is enough of a reason to maintain any skepticism you may have toward the idea of momentum. But at the same time, we should acknowledge that many players believe in the power of momentum, and if that belief influences how they feel, and how they feel contributes to how they perform, then it stands to reason that momentum — or at least, their belief in momentum — has at least some impact on performance.

That’s the last we’ll be discussing momentum here, though I’d encourage you to read the entirety of Speier’s story after you’ve finished reading this mailbag. Instead, today we’ll be answering your questions on players to be named later, the teams that most improved (or diminished) their 2027 playoff odds with their moves at this season’s trade deadline, and where Pete Crow-Armstrong would stack up on the five-star catches leaderboard if we had Statcast data going back through baseball’s history.

We’re less than three days away from the trade deadline, and aside from a challenge trade here and some minor swaps there, the only action we’re getting is inaction. Both Casey Mize of the Tigers and Freddy Peralta of the Mets were scratched from their scheduled starts Friday night, presumably as a precautionary measure to ensure that neither hurler would get hurt ahead of a likely trade.

Of course, we’ve known for a while that the Mets were going to be sellers this deadline season, giving their last-place standing for most of the year. They fired manager Carlos Mendoza at the end of June, and more recently, they’ve been giving every fan a $10 concessions voucher with their ticket, as both an apology for the poor performance on the field and an incentive to keep fans coming to the park to watch that poor performance — which in a few days could get even worse. In addition to Peralta, the Mets are also likely to at least some of their other pending free agents, such as Luis Robert Jr., Tyrone Taylor, Clay Holmes, and Brooks Raley 레일리, as well as high-leverage reliever Luke Weaver, who’s under contract through the end of next season. Detroit’s decision not to start Mize may have something to do with a groin issue that he’s been dealing with recently, as The Athletic’s Ken Rosenthal and Cody Stavenhagen noted. The team let Tarik Skubal, the top pending free agent on the block, start on Thursday even as it is supposedly shopping him. That’s because the Tigers still have about a 1-in-4 shot to make the playoffs, as of the start of play Friday, according to our Playoff Odds. They reportedly haven’t made a final decision on whether they will trade Skubal and their other players on expiring contracts, among them Mize and second baseman Gleyber Torres. If Detroit ends up selling, closer Kenley Jansen, who has a club option for next season, could also be on the move.

In addition to answering your questions about the trade deadline in this week’s Mailbag, we’ll also cover Jordan Hicks’ resurgence with the White Sox, home runs hit slower than the pitch that was thrown, and odd Hall of Fame cap decisions.

Controversy surrounding José Caballero’s pre-pitch routine struck twice in the Bronx this week, with the first time prompting the benches to clear and the second causing unnecessary confusion. In the eighth inning of the Yankees’ 8-5 win over the Pirates on Monday night, Caballero did what he usually does — he dug into the batter’s box and didn’t look up at the pitcher until there were eight seconds left on the pitch timer. The idea is to disrupt the pitcher’s rhythm. Pittsburgh reliever Dennis Santana took exception to Caballero’s tactic — which, again, he has done many, many times for the last four seasons — and yelled at him after getting him to ground into a double play. The benches emptied, and the Pirates complained to MLB about it.

Turns out, the griping worked. After the game, the league told the umpires to more strictly enforce the rules requiring batters to engage with the pitcher with no fewer than eight seconds left on the clock. Instead of warning the batter, and then calling an automatic strike for a repeat violation, the umpires were directed to assess a strike to Caballero for attempting to deceive the pitcher, no matter how much time was left on the pitch timer. Both Caballero and the Yankees claim the league did not notify them about the change. As crew chief Adrian Johnson told a pool reporter after, “He’s been warned all season. We were instructed not to warn him. We were instructed to violate him. That’s what it is. It’s a violation.” Along with Johnson’s poor phrasing, the sudden change in enforcement is quite jarring and, in my opinion, inappropriate. If what the Yankees said is true — that the league didn’t tell them about the change — then I think this is an overstep by MLB to single out a player. Caballero accused the umpires and the league of “picking on” him. But even if MLB did give the Yankees and Caballero the heads up, I think the escalated enforcement is an incorrect interpretation of the rule. I love that Caballero uses the pitch clock to his advantage; pitchers can hold the ball and run down the clock to zero, so why shouldn’t batters be allowed to wait their full allotted time before engaging with the pitcher? Moreover, I also don’t know how Caballero is deceiving the pitcher by doing something he does so frequently. He’s certainly trying to annoy the opposing pitcher, but that’s not deception — that’s good gamesmanship.

Anyway, that’s the last you’ll read about Caballero in this week’s mailbag. Instead, we’ll be answering your questions about Esmerlyn Valdez’s heater, Gunnar Henderson’s woes against fastballs, how to fix the Angels, and whether anyone will break Jesse Orosco’s record for games pitched.

I’ve been thinking a lot about the baseball calendar in recent days, specifically how we use it to both mark the passage of time and look ahead to the possibility of what’s yet to come. As fans, we slice up the season to make it easier for us to discuss noteworthy performances, evaluate trends, and justify our irrational faith that our team just might turn things around. As analysts, we know that we shouldn’t draw grand conclusions from these individual slivers — the sample sizes are just too small — but we also recognize the benefits of using these otherwise arbitrary segments to understand the season as it unfolds.

I mention all of this because this weekend is start of the second half of the season. Of course, we all know that the All-Star break hasn’t been the season’s true midpoint for some time now, as Opening Day is scheduled earlier in the year than it used to be while the All-Star Game continues to be played on the second Tuesday of July. Even so, there are three reasons that I continue to find value in splitting up the season in mid-July. First, pausing the regular season for a few days provides a natural demarcation point. Second, with playoff field now expanded to 12 teams, the postseason lasts longer than ever before. Because the team that wins the World Series could play up to 22 additional games, the All-Star break ends up being much closer to the halfway point on the journey from Opening Day to the decisive game of the Fall Classic. Finally, the three-week stretch after the All-Star Game is a frenetic rush to the trade deadline that then rolls right into the Dog Days of August and the strenuous sprint of September. The games after the All-Star break are much more demanding than the ones before it, thus making the few days of respite in July feel like a more representative dividing line than Game 81 in late June.

Anyway, in this first mailbag of the second half, we’re answering your questions on what it would be like if MLB had a loan mechanism like professional soccer, Kyle Karros’ breakout, the longest time a team has spent within a half-game of .500, and what Anthony Rendon’s career might have been.

Happy Draft Weekend everyone! The draft broadcast begins at 1 p.m. ET today, with the first four rounds scheduled for Day 1. Then, tomorrow, the draft resumes at 11:30 a.m. ET for rounds 5-20.

As always, FanGraphs has you covered with everything you need to know before, during, and after the draft. Eric Longenhagen, Brendan Gawlowski, Michael Baumann, and Meg Rowley are in Philadelphia providing coverage throughout the weekend. You can find all of our draft coverage here, or by using the navigation widget at the top of our homepage and in our draft pieces. Eric and Brendan’s updated draft rankings are available on The Board, where you’ll also find players’ scouting reports and tool grades. You can read Eric’s draft preview here, and his first mock draft here. Provided he has enough new information to merit one, his second mock draft will run today before the first round, so be on the lookout for that, too. Meanwhile, Michael wrote three excellent draft features, which you can read here, here, and here. Also, be sure to join our Day 1 draft chat, where the FanGraphs crew will be answering your questions and providing updates and analysis beginning at 1 p.m ET.

That’s the last you’ll read about the draft in this mailbag. Instead, we’ll be answering your questions about Pete Crow-Armstrong, Aaron Ashby’s propensity for wins, and games with the highest rates of true outcomes for one team. Plus, I’ll provide the answers to last week’s trivia questions about baseball stats featuring the number 250. But first, I’d like to remind you that this mailbag is exclusive to FanGraphs Members.

Happy Fourth of July! To commemorate the United States’ Semiquincentennial, I’m going to run through some fun baseball stats that feature the number 250, and also ask a few trivia questions, which you can answer in the comments. As of Thursday morning, there is one player in MLB history with exactly 250 career home runs. He’s an active player for an NL West team. Can you name him? Seven players have recorded exactly 250 doubles in their career; only one of them is in the Hall of Fame. The six non-Hall of Famers are Ozzie Albies, Travis Hafner, Deivi Cruz, Bruce Bochte, Irish Meusel, and Jake Daubert. The Hall of Famer is a 19th century catcher. Who is it?

There are 25 members of the 250 Home Run/250 Stolen Base Club, nine of whom are Hall of Famers. Sorted by home runs, those nine are Willie Mays (660 HR, 339 SB), Andre Dawson (438, 314), Carlos Beltrán (435, 312), Rickey Henderson (297, 1,406), Craig Biggio (291, 414), Ryne Sandberg (282, 344), Joe Morgan (268, 689), Derek Jeter (260, 358), and Robin Yount (251, 271). Two others are active: José Ramírez (295, 311) and Jose Altuve (263, 326). Can you name the other 14 members of the 250/250 Club? Lastly, seven players have tallied at least 250 hits in a season. Six of them — Ichiro Suzuki (262 in 2004), George Sisler (257 in 1920), Bill Terry (254 in 1930), Al Simmons (253 in 1925), Chuck Klein (250 in 1930), and Rogers Hornsby (250 in 1922) — are Hall of Famers. Can you name the one non-Hall of Famer?

I’ll reveal the answers in next week’s mailbag. In this week’s edition, we’ll answer your questions on challenging the first pitch of a game, sustained runs of low playoff odds, a team of Frank Thomases and Luis Aparicios, and more.

The first thing to know about the firing of Carlos Mendoza is that nobody in the Mets’ clubhouse believes their poor performance is the former manager’s fault. Not David Stearns, the president of baseball operations. Not Francisco Lindor, the franchise shortstop. Not Bo Bichette, the big offseason acquisition. Not Andy Green, the farm director-turned-interim manager. Mendoza did not lose the clubhouse, Stearns said at a press conference Friday afternoon, less than six hours after the team announced the dismissal, while Lindor said he and the players failed Mendoza.

It would be easy to point to the embarrassing series the Mets just played against the Cubs at Citi Field, the low point coming in the second game of Wednesday’s doubleheader. Each of the four infielders made at least one error; that hadn’t happened since Sept. 8, 1962. New York recorded six defensive miscues in total. But the truth is, neither one game nor one series did Mendoza in. The only thing surprising about his firing is that it didn’t happen sooner. The Mets went 34-47 (.420) under Mendoza this season, making them the third-worst team in the National League. On June 12, 2025, the Mets held the best record in the majors. As of Friday morning, they had a record of 72-102 (.414) since that high-water mark. This is a team in free fall, and the descent has lasted for longer than a full calendar year. During the offseason, Stearns and the Mets cleaned house of most of their veteran players and brought in a new group of guys. That hasn’t worked through the first 81 games of the season, and so the next thing to do was fire the manager. Stearns said during his press conference on Friday that his own job is safe, that he has the support of ownership. The thing is, so did Mendoza — until he didn’t.

Jay Jaffe will take a more detailed look at Mendoza’s firing and the Mets in a story early next week, so that’s the last I’ll say about the news in this week’s mailbag. Instead, we’ll be answering your questions about the unwritten rules of ABS challenges, what would happen if a team were made up of nine Frank Thomases, the amount of money a player would make from spending just 24 hours on a big league roster, and more.

Last season, despite his team’s struggles, Byron Buxton set career highs in plate appearances (542), home runs (35), runs (97), RBI (83), hits (129), and WAR (5.0). He only played in 126 games, his second-highest single-season total, because he made two separate trips to the injured list. We saw enough of him in 2025 to appreciate his astonishing abilities, yet at the same time, his presence was a reminder of the career that might’ve been if only he hadn’t gotten hurt so much.

Fortunately, Buxton is healthy again this season. As of Friday morning, he has played in 64 of the Twins’ 76 games this year. That might not seem like a lot, but that works out to a pace of 136 games. Crucially, despite dealing with a few minor injuries, he has avoided the IL so far in 2026. He’s on track to hit 49 home runs and accumulate just shy of 6 WAR. ZiPS and our Depth Charts both project him to slow down a little bit, but they still peg him for at least 45 homers and right around 5 WAR. That would be an impressive season for anybody, but especially for an injury-prone 32-year-old center fielder.

That bit on Buxton is all you’ll hear from me this weekend. I’m on vacation as you’re reading this, and Meg Rowley is handling mailbag editing duties while I’m gone. This week, we’re answering your questions on Juan Soto’s slower swing speed, the teams that have the greatest all-time differences between player WAR and franchise wins, and whether an American League team will make the playoffs with a losing record.
