He batted and threw right-handed. Unglaub stood and weighed . A Baltimore native, Unglaub was first exposed to baseball when he served as batboy and mascot for the Baltimore Orioles. He made his major league debut with the Highlanders in 1904 and was traded to Boston later that year. Though he started at first base for Boston in late 1905, he played minor league baseball in 1906 because of a salary dispute. Back with the Americans in 1907, he became their full-time first baseman and even their manager, though the latter role lasted for only 29 games. He was traded to Washington in 1908 and remained with the Senators through the 1910 season. Unglaub then played in the minor leagues for six more years before he was killed in an accident while working at Baltimore's Pennsylvania Railroad shops. Early life Born in Baltimore, Maryland, on July 31, 1881, Unglaub was the son of John and Minnie Unglaub. He grew up a mere three blocks away from Union Park, home of the Baltimore Orioles. In his formative years, he served as batboy and mascot for the ballclub, receiving baseball tips and advice from players such as John McGraw, Joe Kelley, Willie Keeler, and Steve Brodie. Unglaub would often catch fly balls hit by the players during batting practice. Upon Unglaub's graduation from high school in 1897, a representative of the University of Maryland inquired about Unglaub's interest in attending the institution. Unglaub said he wanted to play baseball, then discovered he could do both; the school would pay him $75 a month to play baseball for the Terrapins. Accepting the offer, Unglaub attended the school for three years, pitching under his middle name of Alexander and acquiring an engineering degree. During his time in college, Unglaub also played for a variety of amateur and semipro teams on Maryland's Eastern Shore.
