The Minneapolis Millers left the Twin Cities on May 19, 1951, to start a road trip in Milwaukee. Willie Mays, a center fielder who had turned 20 two weeks earlier, went 4-for-5 with a triple, a home run and two RBI.
The Millers went 3-3 on the trip to Milwaukee and Kansas City. Mays was 14-for-29 with eight RBI and seven extra-base hits. This put his average in 35 games in the Class AAA American Association at .477, to go along with eight home runs and 30 RBI.
The young man's on-base percentage was .524, his slugging percentage was .799 and, if it was 60 years later, Halsey Hall, the Minneapolis sportswriter and broadcaster, would have said:
"Holy cow, Mays has an OPS of 1.323."
Memorial Day was getting near. That would be the unofficial start of the summer baseball season, and Millers fans were preparing to descend on Nicollet Park to see this phenomenon of the New York Giants farm system.
The Millers stopped in Sioux City, Iowa, on the way back from Kansas City to Minneapolis. They were scheduled to play the Soos, a Class A farm club of the Giants, in an exhibition game May 24.
Mays went to a movie early in the day, as was his custom on the road. "A message came on the screen: 'Willie Mays Go To Lobby,' " Mays said in a recent interview in San Francisco. "I thought something bad might've happened with my family."
Mays was told by a theater employee to go immediately to Millers manager Tommy Heath's room at the team hotel. It was there that Willie Mays, 11 months after his high school graduation in Fairfield, Ala., was informed that he was going to New York to sign a big-league contract and take over as the center fielder for the Giants.
