Gibson was born in
London, Ontario, near Tecumseh Park, the oldest continually operating baseball grounds in the world (today's
Labatt Memorial Park). He gained the nickname "Mooney" as a youngster. Some sources suggest that the nickname was inspired by his round, moon-shaped face, while other sources claim he picked up the nickname because he had played on a
sandlot team known as the Mooneys. Numerous sources still associate Gibson with the
Kingston Colonials of the
Hudson River League but in a 1919 article, journalist Edward F. Balinger discusses this topic. Relaying something said by Gibson days earlier, he suggests that "somebody got him mixed with some other player shortly after he broke into the big league." George spent parts of two seasons playing for the
Montreal Royals before his contract was purchased by the Pittsburgh Pirates in June 1905. Gibson was in his prime during the
1909 season when he caught in 134 consecutive games, breaking the previous record of 133 consecutive games played as a catcher set by
Deacon McGuire in 1895. He set another major league record for games played in a season by a catcher with 150, which was also previously held by McGuire since 1895. His games caught in a season record stood until 1920 when
Ray Schalk caught 151 games. His record of 134 consecutive games caught would stand until 1940 when it was broken by
Ray Mueller. Gibson hit a
double for the final hit in the last game played at Pittsburgh's
Exposition Park on June 29, 1909, and the following day had the first hit in the new
Forbes Field. He also led National League catchers in
fielding percentage,
baserunners caught stealing and in
caught stealing percentage. Gibson then went on to catch every game in the
1909 World Series as the Pirates defeated the
Detroit Tigers in seven games to win the world championship. Gibson held Detroit's
Ty Cobb, the premier base stealer of his era, to only one stolen base during the series (Cobb also stole home plate during the series which wasn't charged against Gibson). Arriving back at the train station in his hometown of
London, Ontario, on October 27, 1909, after winning the World Series, Gibson found more than 7,000 cheering fans to greet him. As the sport evolved, teams began to field smaller, more agile players as catchers, typified by the emergence of
Ray Schalk. Gibson returned to hit for a career-high .285
batting average in 102 games during the
1914 season. Giants manager
John McGraw persuaded him to join the Giants as a player-coach in
1917. Gibson played in his final major league game on August 20,
1918 at the age of 38. ==Career statistics==
