NEW-YORK TIMES, Sept. 23, 1870  

* Historic "Telegraph" baseball game

Page 3 has: "Base-Ball The Championship Contest--Mutual vs. Atlantic--The Mutuals Win the Champion Pennant --Score 10 to 4". The summary (see) mentions that there was: "...a very large gathering of spectators on the Union Grounds...despite the fact that the admission fee was double the usual charge." Also says there was the largest gathering of fence peepers ever seen at a baseball match, and because there was such an interest in the game: "...the telegraph companies laid a wire to the grounds, and at the close of each inning, the result was telegraphed direct to Cincinnati, St. Louis, Chicago, Boston and New Orleans." Many other particulars about the excitement and the game. Includes the box score. A great report with a touch of baseball history.
Eight pages, very nice condition.
Note: "The Mutuals win the much-debated championship for 1870 by defeating the Atlantics 10-4 at Union Grounds. The game had such interest that inning by inning results are sent nationwide via telegraph wires. Several clubs would lay claim to the championship that year."

Background: The September 23, 1870, match between the Mutual Club of New York and the Brooklyn Atlantics at Williamsburg’s Union Grounds—the nation's first enclosed baseball park—marked a landmark moment in early American sports history as the Mutuals claimed a 10–4 victory to capture the heavily disputed 1870 championship pennant. Played during a chaotic era before formal league structures existed, when titles were decided by challenge matches, the game generated unprecedented national fan passion, drawing a massive paying crowd despite a doubled admission fee along with the largest gathering of "fence peepers" ever recorded. Most significantly, the game demonstrated baseball's rapid transition into a major media spectacle as telegraph companies ran a dedicated wire directly to the grounds to broadcast inning-by-inning scores nationwide to major cities like Cincinnati, Chicago, Boston, and New Orleans, foreshadowing the modern era of real-time sports journalism and national fanbases.
