Roger Angell, the elegant and thoughtful baseball writer who was widely considered among the best America has produced, died on Friday at his home in Manhattan. He was 101.

The cause was congestive heart failure, his wife, Margaret Moorman, said.

Mr. Angell’s voice was original because he wrote more like a fan than a sports journalist, loading his articles with inventive imagery.

The Boston Red Sox catcher Carlton Fisk came out of his crouch, Mr. Angell wrote, like “an aluminum extension ladder stretching for the house eaves.” The Baltimore Oriole relief pitcher Dick Hall pitched “with an awkward, sidewise motion that suggests a man feeling under his bed for a lost collar stud.” Mr. Angell (pronounced angel) described Willie Mays chasing down a ball hit to deep center field as “running so hard and so far that the ball itself seems to stop in the air and wait for him.”

The baseball season didn’t seem complete until, as he did late each fall, Mr. Angell wrapped up its multiple meanings in a long New Yorker article. Many of his pieces were collected in books, among them “Late Innings” (1982) and “Once More Around the Park” (1991).

But he wrote not just about teams and the games they played. He also considered what it meant to be a fan.

“It is foolish and childish, on the face of it, to affiliate ourselves with anything so insignificant and patently contrived and commercially exploitative as a professional sports team,” he wrote in his book “Five Seasons” (1977). “What is left out of this calculation, it seems to me, is the business of caring — caring deeply and passionately, really — which is a capacity or an emotion that has almost gone out of our lives.”

For Mr. Angell, The New Yorker was, to some degree, the family shop. His mother, Katharine Sergeant Angell White, was among the magazine’s first editors hired by Harold Ross in 1925. His stepfather, the essayist E.B. White, was a frequent contributor. Mr. Angell published his first piece in the magazine, a short story, in 1944 and went to work there in 1956.

Like his mother, Mr. Angell became a New Yorker fiction editor, discovering and nurturing writers, including Ann Beattie, Bobbie Ann Mason and Garrison Keillor. For a while he occupied his mother’s old office — an experience, he told an interviewer, that was “the weirdest thing in the world.” He also worked closely with writers like Vladimir Nabokov, John Updike, Donald Barthelme, Ruth Jhabvala and V.S. Pritchett.

Mr. Angell was known, too, for his annual page-long holiday poem, titled “Greetings, Friends!” The poem, a New Yorker tradition, began in 1932 and was originally written by Frank Sullivan. Mr. Angell wrote “Greetings, Friends!” from 1976 until 1998, when it went on hiatus, and restarted it in 2008. In recent years, the poem has been written by Ian Frazier.

In his holiday poems, Mr. Angell mixed the boldface names, from high culture and low, that had filtered through that year. Here is a snippet from 1992:

Some of his rhymes could be read mischievously. “Yo! Santa man, grab some sky,” he wrote in 1992, “And drop a sock on Robert Bly.”

“I’m not sure there’s ever been a writer so strong, and an editor so important, all at once, at a magazine since the days of H.L. Mencken running The American Mercury,” David Remnick, The New Yorker’s editor, said in an interview for this obituary in 2012. “Roger was a vigorous editor, and an intellect with broad tastes.”

Mr. Angell became a baseball writer by accident. He was already a fan in 1962 when, he told an interviewer for Salon, he was asked by William Shawn, the magazine’s editor, to “go down to spring training and see what you find.”

It was an auspicious year to be a young baseball writer: the first season of the New York Mets. “They were these terrific losers that New York took to its heart,” Mr. Angell said.

The tone of his baseball writing, he once said, was inspired by a now canonical John Updike article, written in 1960, about Ted Williams’s final game at Fenway Park in Boston. “My own baseball writing was still two years away when I first read ‘Hub Fans Bid Kid Adieu,’” Mr. Angell wrote, “and though it took me a while to become aware of it, John had already supplied my tone, while also seeming to invite me to try for a good sentence now and then, down the line.”

Mr. Angell was sometimes referred to as baseball’s poet laureate, a title he rejected. He called himself a reporter. “The only thing different in my writing,” he said, “is that, almost from the beginning, I’ve been able to write about myself as well.”

He disliked sentimentality about sports. “The stuff about the connection between baseball and American life, the ‘Field of Dreams’ thing, gives me a pain,” he once said. “I hated that movie.”

He was alert, however, to what he called the “substrata of nuance and lesson and accumulated experience” beneath baseball’s surface. And his humor flashed above all this.

He once referred to Ron Darling as “the best right-handed part-Chinese Yale history major among the Mets starters.” He wrote that Carl Yastrzemski, “like so many great hitters, has oddly protuberant eyes.” And he noted, about a skinny Houston Astros team, that “they sometimes suggest a troupe of gazelles depicted by a Balkan corps de ballet.”

He was born in Manhattan on Sept. 19, 1920. His father, Ernest Angell, was a graduate of Harvard Law School, a World War I veteran and a former semipro pitcher who in 1950 became the national chairman of the American Civil Liberties Union. After his parents were divorced, Mr. Angell continued to live in Manhattan with his father.

He graduated from Harvard in 1942 and then worked as a magazine editor for the Army Air Forces. After his discharge he was a writer for Holiday magazine and wrote frequently for The New Yorker before being hired.

Some at the magazine resisted his hiring. “The staff just felt they’d had enough of the Whites,” he said. “But Shawn came to me and made me an offer.”

Much of his early writing for the magazine was fiction. A collection of his short stories, “The Stone Arbor,” was published in 1960.

In The Atlantic Monthly in 1997, Mr. Keillor noted that Mr. Angell was an “old-fashioned seigneur of an editor,” the sort “who was terribly generous with his praise and apologetic for his criticism and who, if a month passed without submissions from me, would write the most wonderful encouraging letters.”

Ben Yagoda’s history of The New Yorker, “About Town” (2000), reprinted an extended series of rejection letters from Mr. Angell to Ms. Beattie over 22 months in the early 1970s. He turned down story after story, with advice and encouragement, until she submitted one titled “A Platonic Relationship” in 1974. Mr. Angell responded by writing, “Oh joy.”

Mr. Angell had his critics, some of whom felt that The New Yorker’s fiction under his watch was insular. Reviewing Mr. Angell’s memoir “Let Me Finish” in The New York Times Book Review in 2006, the British critic James Campbell wrote: “There is no ethnic friction in Angell’s America (which the outsider might imagine ranging from the Upper East Side to the Hamptons), no poverty, no crime and next to no politics. But there is wit and charm and sometimes wisdom.”

Like his stepfather, E.B. White, Mr. Angell spent a good deal of time in coastal Maine, where he owned a home on Eggemoggin Reach in Brooklin. Also like his stepfather, Mr. Angell was an enthusiastic consumer of martinis. He composed an essay, “Dry Martini,” that some consider the best on the subject. In it, he admitted that he ultimately moved to vodka from gin because vodka was “less argumentative.”

He loved smooth fox terriers and owned several over the years. One of his great pleasures was to walk his dog around the Madison Avenue neighborhood where he lived on the Upper East Side.

He wrote well into his 90s. In 2014 he was awarded the J.G. Taylor Spink Award, the Baseball Hall of Fame’s honor for writers. In 2015, when he was 94, he published a collection of essays, holiday poems and other writings entitled “This Old Man.”

“I’ve endured a few knocks but missed worse,” he wrote in that book. “I know how lucky I am, and secretly rap wood, greet the day, and grab a sneaky pleasure from my survival at long odds. The pains and insults are bearable.”

Until his final years, Mr. Angell attended as many as 40 baseball games a year, rooting for the Mets, the Giants, the Red Sox, the A’s and even sometimes the Yankees.

His first wife was Evelyn Baker, whom he divorced in 1963. The following year he married Carol Rogge, who taught reading at the private Brearley School in Manhattan and who died in 2012. In 2014, he married Ms. Moorman, a writer and retired teacher.

In addition to her, he is survived by a son, John Henry, whom Mr. Angell and his second wife, Carol, adopted; a stepdaughter, Emma Quaytman, through his marriage to Ms. Moorman; a brother, Christopher; a sister, Abigail Angell Canfield; three granddaughters; and two great-granddaughters. A daughter from his first marriage, Callie Angell, died by suicide in 2010. Another daughter from that marriage, Alice Angell, died of cancer in 2019.

Baseball is “a great game for writers because it’s just the right pace,” Mr. Angell once said. “You can watch the game and keep score and look around and take notes. Now and then you even have time for an idea.”

And, he said, he loved the way “baseball will stick it to you; it means to break your heart.”
