Guerrero is considered one of the greatest batters of all time, and is widely regarded as the best "bad ball" batter of all time (the ability to hit pitches outside of the strike zone). He was well known for putting the ball into play, and particularly on the first pitch. He had exceptional hands at the plate, and would bat without batting gloves. Guerrero was able to hit for both power and average. In the outfield, Guerrero was sometimes considered a defensive liability, prone to making errors, which resulted in him being a designated hitter in the last stage of his remarkable career, but he was also known to have a very powerful throwing arm that allowed him to make outfield assists on base runners.
