Boros concluded that Santo was the best third baseman he had ever seen. Previously, Boros had tried to be a "cool, graceful player of the Gil McDougald type." Based on his observation of Santo, he changed his philosophy and changed into "a scrambling, aggressive type." He later described the 50-game errorless streak as his biggest thrill in baseball. During the 1964 season, Boros started 113 games at third base, compiling a .257 batting average and .342 on-base percentage in 370 at-bats.
