1951 Bob Nieman's Second Home Run in First Two Major League At-Bats Baseball. Until Keith McDonald duplicated the feat in 2000, Nieman owned the distinction of having been the only player in Major League history to homer in his first two at-bats, and likewise the first to homer twice in his debut appearance (Bert Campaneris and Mark Quinn have since made it a trio). Presented is the very ball that earned Nieman these bragging rights, clubbed as his hapless St. Louis Browns visited the Red Sox at Fenway. The heavily worn OAL (Harridge) ball bears a vintage notation, since partially enhanced to improve legibility, which reads, "Record setting ball home runs first two at bats. This is the second one," and "2nd HR 1st Game, Sept. 15, 1951 off Mickey McDermott."
