Juan Bautista Berenguer [beh-ren-gher'] (born November 30, 1954) is a former Panamanian long relief pitcher in Major League Baseball (MLB) who played for eight teams from 1978 to 1992. Listed at 5'11 (1.80 m), 200 lb. (91 k), Berenguer batted and threw right-handed. He was born in Aguadulce, Coclé, Panama. A mean-looking, husky pitcher with long hair and a mustache, Berenguer was nicknamed 'Pancho Villa' by his teammates, and Twins fans admiringly referred to him as 'Señor Smoke' or 'El Gasolino' due to his mid-90s mph fastball.
