 For whatever reason, the parent Cincinnati Reds assigned him to Dothan for a second season in 1959, and he responded by bopping out a .337 average and again led the circuit with 46 steals.Sufficiently impressed, the Reds moved Acosta up to the Billings Mustangs of the Class C Pioneer League the next season, where he topped the loop with a .369 average (the first of his five pro batting crowns) and 45 swipes.He leapfrogged over B ball in 1961 to play for Class A Columbia Reds of the South Atlantic League, and once more was best in the league in batting (.343) and steals (40), marking his fourth consecutive stolen base titles.
