Carl Crawford
Under the pre-modern rule, George Gore stole 7 bases in a game in 1881, a mark that was tied by "Sliding Billy" Hamilton in 1894. In the modern era, Eddie Collins stole 6 bases in a game on two occasions, both in September 1912, a mark that stood alone for nearly eight decades before being tied by Otis Nixon (1991), Eric Young (1996), and Carl Crawford (2009).
