Answer:
Yogi Berra
Yogi Berra won the AL MVPs in 1954 and 1955. In the period between 1950 and 1956, Berra never finished below fourth place in MVP balloting, winning in 1951, 1954, and 1955, second in 1953 and 1956, third in 1950, and fourth in 1952. Yogi was famous even beyond baseball for his "Yogisms", quotes that don't seem to make sense at first blush, such as, "It ain't over 'til it's over".
