Pete O'Brien (1900s second baseman)

Peter "Pete" O'Brien (born c. 1877, death date unknown) was an American professional baseball player who primarily played second base in the early 1900s. His Major League Baseball (MLB) career consisted of brief stints with several teams.

O'Brien's MLB debut came with the Pittsburgh Pirates in 1901, where he played in a limited number of games. He later played for the Philadelphia Phillies in 1902. His final MLB appearance was with the Washington Senators in 1904.

While precise statistics are often incomplete for players of this era, historical records indicate he was a utility player capable of filling in at various positions. He did not achieve significant recognition or lasting fame in his career, largely due to his limited playing time and lack of exceptional offensive or defensive performance.

Further details about his early life, minor league career, and post-baseball life are scarce. He remains a relatively obscure figure in baseball history, primarily known for his brief appearances in the major leagues during a transitional period for the sport.
