In 1957, when he was 38-39, Williams hit .388 with 38 home runs, a .526 on-base percentage, and a .731 slugging percentage. He led the major leagues in all those categories, except home runs. And he struck out 43 times in 420 at-bats.
He did not play at all in 1943, 1944, and 1945, when he was 24-27. He played only a little bit in 1952 and 1953, when he was 33-35. So he missed almost five full seasons in the prime of his career, when his numbers would have been at their highest.
What a hitter.
