"The two best batters in my first seven years in the National League were the late Roberto Clemente and Hank Aaron. These men were gifted with natural ability more than others. Each one of them, day in and day out, year after year, did his job superlatively. They made very few mistakes as hitters; they did not try to overpower the ball, but they hit it as far and as often as any batters ever have. Aaron and Clemente were the true superstars of the National League. They ran, threw, hit, and did everything required of a baseball player as well as it could be done. If they went without a hit on one day, you knew that they were going to get three or four the next. Their ability was natural, but they worked hard to maintain it."
