Bob Nieman (January 26, 1927 - March 10, 1985) was a Major League Baseball outfielder and right-handed batter who played for the St. Louis Browns (1951-52), Detroit Tigers (1953-54), Chicago White Sox (1956), Baltimore Orioles (1956-59), St. Louis Cardinals (1960-61), Cleveland Indians (1961-62) and San Francisco Giants (1962).
Nieman was born in Cincinnati, Ohio. He was signed by the Cincinnati Reds as an amateur free agent in 1948 and made his debut with the Browns.
On September 14, 1951 at Fenway Park, Nieman hits two home runs in his first two major league at-bats. He became the first player in big league history to hit two homers in his first game. Bert Campaneris (1964) and Mark Quinn (1999) are the only others to accomplish the feat. Also, Nieman is one of two players in MLB history to hit HRs in each of his first two big league at bats. Keith McDonald, in 2000, is the other.
Nieman became an everyday St. Louis outfielder and later played regularly for the Tigers and Orioles. In his 1113-game career he batted .295, with 125 home runs, 544 RBI, 455 runs, 1018 hits, 180 doubles, 32 triples and 10 stolen bases. After retiring he played in Japan and later served as a scout for the Indians, Dodgers, Athletics, White Sox and Yankees.
Bob Nieman died in Corona, California at 58 years of age.
