Willie Mays – 51
The Korean War put Mays’ career on hold but he exploded into life when he returned. First, he hit 41 home runs in 1954 and won the NL MVP award. But he went even further the following year when he hit another 10 to take his season total to a superb 51 (via MLB.com).

There’s no denying that Mays was one of the best sluggers of his day. The then-24-year-old posted superb statistics compared to his rivals but he didn’t win a consecutive MVP award. This was controversial at the time but he was happy to help the Giants win another pennant.
