John Joseph Barry was an American shortstop, second baseman, and manager in Major League Baseball, and later a college baseball coach. From 1908 through 1919, Barry played for the Philadelphia Athletics (1908–1915) and Boston Red Sox (1915–1919).

The $100,000 infield was the infield of the Philadelphia Athletics in the early 1910s. The $100,000 infield consisted of first baseman Stuffy McInnis, second baseman Eddie Collins, shortstop Jack Barry and third baseman Frank "Home Run" Baker. According to the Encyclopædia Britannica, the nickname reflects "the purported combined market value of the foursome", which is equivalent to about $2.38 million in 2023.
