"Alou's career blossomed in 1966 after he was traded to Pittsburgh, where Pirates Manager
Harry Walker helped the left-handed-hitting Alou revamp his swing. Alou choked up on a heavier bat and often hit off his front foot, flicking his wrists at pitches and flaring many balls to left field. His unorthodox style wasn't pretty. Hall of Famer

Steve Carlton once called Alou 'the worst .300 hitter I've ever seen.' But it worked. Alou hit .342 with 18 doubles, nine triples and 86 runs in 1966 and edged out his brother,
Felipe, for the batting title." - By Mike DiGiovanna in the Los Angeles Times (11/03/2011, 'Matty Alou dies at 72; one of three baseball-star brothers',
