Major League Baseball Player. He played Major League baseball for eleven seasons (1908 to 1917, 1919) with the Philadelphia Athletics and Boston Red Sox. Scouted and signed after playing for Holy Cross College by Connie Mack’s Athletics, he would play a significant role in helping Philadelphia win four American League Pennants during his time with the club. Teamed with first baseman Stuffy McInnis, second baseman Eddie Collins, and third baseman Frank “Home Run” Baker, they formed what was dubbed the "$100,000 Infield". While not spectacular at either the plate or in the field, Jack Barry was a steady solid player who gained a reputation as a leader on Mack's powerhouse deadball era teams. In 1910 he helped the team run away with the Pennant, and was a part in the Athletics 4 Games to 1 World Series championship over the Chicago Cubs. In 1911 and 1913 the A's met John J. McGraw’s New York Giants in the Series, beating them 4 Games to 2 in their first meeting (with Jack Barry batting .368) and 4 Games to 1 in the second meeting. However, in the 1914 World Series, where Jack Barry and the A's were heavy favorites over the "Miracle" Boston Braves, Barry managed only one hit in 14 At-Bats as the Rabbit Maranville -led Braves swept the Philadelphia in one of the most stunning upsets in baseball to that time. His tenure with the A's would last half a season more, as Connie Mack, feeling financial pressure caused by the formation of the Federal League, broke up the "$100,000 Infield", selling star second baseman Collins to the Chicago White Sox in December 1914, and Jack Barry to the Boston Red Sox on July 2, 1915 (ironically, his first game in a Red Sox uniform was the next day against the A's). Switching to second base, with Boston he helped propel a team that carried future Hall of Famers Harry Hooper and Tris Speaker (and a young pitching phenom name Babe Ruth) to an American League Pennant, Jack Barry's fifth in six years. He only hit .176 in 5 games against the National League champion Philadelphia Phillies, but the Red Sox downed them 4 Games to 1 to win the 1915 Series. Although the Red Sox repeated as AL and World Series champs in 1916 (defeating the Brooklyn Robins 4 Games to 1), he did not play in the Series. After the season Red Sox manager Bill Carrigan stepped down, and Jack Barry was named to lead the team. As their player-manager, he guided them to a 90 win season in 1917, but fell short behind the Chicago White Sox. He enlisted in the United States Navy after the United States entered World War I, and missed the 1918 season and the Red Sox’s World Series win over the Chicago Cubs (it would be Boston’s last World Series title until 2004). When he came back from his war service, the team was under the new ownership of Harry Frazee. During his tenure Frazee would use the money from selling off some of his prized players to funds his Broadway productions (his most famous sale being that of Ruth to the Yankees). After 31 games he traded Jack Barry back the A's on June 27, 1919, but he decided to retire then return to his old team. He went on to coach Holy Cross’ baseball team for many years. His career totals were 1,223 Games Player, 1,009 Hits, 532 Runs, 10 Home Runs, 429 Runs Batted In, and a career .243 Batting Average.
