Wikipedia - "Jack Eugene Jensen (March 9, 1927 – July 14, 1982) was an American right fielder in Major League Baseball who played for three American League teams from 1950 to 1961, most notably the Boston Red Sox. He was named the AL's Most Valuable Player in 1958 after hitting 35 home runs and leading the league with 122 runs batted in; he also led the league in RBI two other years, and in triples and stolen bases once each. Respected for his throwing arm, he won a Gold Glove Award and led the AL in assists and double plays twice each. He retired in his early thirties as baseball expanded westward, due to an intense fear of flying."
