 Peña spent all of on the Cincinnati roster, and got into 46 games.But his effectiveness declined, and he would bounce between Triple-A and the majors for the next three seasons.Acquired by the Kansas City Athletics in August 1962, Peña was plugged into the second-division team's starting rotation and won six of ten decisions, posted a solid 3.01 earned run average and threw six complete games, including a three-hit shutout against the Angels on August 29.
