James Nathaniel Halpin (October 4, 1863 - January 4, 1893), a native of England, was a Major League Baseball shortstop/third baseman. He played for the Worcester Ruby Legs (1882), Washington Nationals (1884 Union Association), and Detroit Wolverines (1885). At just 18 years of age, he was the youngest player to appear in a National League game in 1882.
Halpin made his major league debut in a home game against the Buffalo Bisons at Worcester Driving Park Grounds. The Ruby Legs defeated future Hall of Famer Pud Galvin 6-3. Halpin played just one more game for Worcester before returning to the big leagues two years later.
Halpin passed away at the age of 29 in Boston, Massachusetts.==External links==
