Look back further into Billiards for the best players.
Our history goes back farther than the 1900's.
Who was the best billiards and pool player of all time? ... Harold Worst, Willie Hoppe, Alfredo de Oro, Johnny Layton, Willie Mosconi, Mike Sigel, Earl Strickland, or Efren "The Magician" Reyes?
Some of the choices are subjective. For instance, while Harold Worst probably was the best three-cushion billiards and pool player in his prime ("and" being the key word), the other players named were dominant for much longer periods of time. But Hoppe was primarily a three-cushion billiards player. Mosconi was a straight pool specialist. De Oro, to my knowledge, never won a major championship in nine-ball, one-pocket or snooker. Layton won twelve three-cushion billiard titles, but only two in pocket billiards and both were in straight pool. Sigel and Strickland were nine-ball experts who never played high-level three-cushion billiards. Only Harold Worst won all the following in a single season: the three-cushion billiards world championship, two major all-round pool world championships (straight pool, one pocket and nine-ball), and an English snooker tournament. And he did it while dying of brain cancer, in his last year on the planet. Other players remarked how sick he looked, even as they marveled at how magnificently he played. Top pros like Luther "Wimpy" Lassiter and Eddie "The Knoxville Bear" Taylor dodged Worst; others demanded mortal locks before they'd gamble with him. And yet sometimes when Worst gave other pros the "absolute nuts," he still won. As one pro put it, everyone "shook" when they played Worst, even when they had talked him into ridiculous spots. So Harold "the Best" Worst gets my vote, for whatever it's worth.
Another interesting player to consider as the best ever is Albert M. Frey, who was winning nearly every match almost as soon as the first native American pool games had been invented. According to Michael Phelan, the father of American pool, the first national pool championship took place in 1878. Albert Frey the "blonde boy" wonder and darling of the crowds, made his public debut on December 30, 1880. He won the first professional eight-ball tournament at Republican Hall, NYC, in May 1882. He became the world champion of another new game, fifteen-ball or 61-pool, also in 1882. By 1884, Frey was "almost invariably winning" according to Phelan, while competing against stars like George F. Sutton, James L. Malone, Cyrille "The Bismarck of Billiards" Dion, Alfredo de Oro and Jake "The Wizard" Schaefer. From 1881-1887, Frey won every fifteen-ball championship match or finished second. In 1888, Frey won the first continuous pool (straight pool) tournament, beating Malone in a playoff. In 1889, Frey was tied for first place in the national championship tournament, when he died suddenly of pneumonia. At the time of his death, he had been dominating the American pool scene, whether the game was fifteen-ball, eight-ball or continuous pool. Frey was "widely known as the champion pool player of America," according to his obit in The New York Times. Malone had a crown delivered to the funeral, a touching tribute since he had been Frey's greatest and most determined obstacle to the crown.
If we can look northward, another fascinating player is Cyrille Dion, a French-Canadian born in Montreal in 1843. Dion was the billiards champion of Canada in 1865, at age 22, with a high run of 138 and a grand average of 12.76. He won the 1866 Tournament of State and Provincial Champions, again going undefeated with a high run of 127 and a grand average of 11.28. In 1870-1871 he won a series of four-ball championship matches against stars who included the French champion A. P. Rudolphe and Americans Frank Parker and Melvin Foster. Dion won the American four-ball championship in 1873, with a high run of 127 and a grand average of 11.28. He won the straight rail championship in 1875. In 1876 Dion won the four-ball championship by such a wide margin, 1500-392, that The New York Times predicted there would never be another four-ball championship match. In 1878, Dion won the first American National Championship pool tournament. He died just six months later, at age 35, from severe lung congestion that had plagued him for years. He was the undefeated champion of the first major Canadian billiards tournament, the undefeated champion of the last American four-ball billiards tournament, and the undefeated champion of the first major American pool tournament. He had nerves of steel and was ready, willing and able to play anyone, as reported by the Fort Wayne Daily Gazette on July 18, 1871: "Cyrille Dion has issued a notice in which he challenges anyone in the world to play him a game of three-ball or French carom billiards, the amount of stakes to be not less than five hundred dollar a side. It is thought in billiard circles that an International contest will be the result of this challenge."
In the modern era, Efren "The Magician" Reyes may well be the best all-around player. Reyes is a master of eight-ball, nine-ball, ten-ball, rotation, one-pocket, straight pool, snooker, 18.1 balkline and three-cushion billiards. And he claimed the richest purse in pool history, $163,172 in the 2001 Tokyo Nine-Ball Championship. But whether he's better than Worst is a matter of speculation, if you'll pardon the pun.
