In a message read out to the crowd, fellow Cuban and White Sox star Alexei Ramirez, who was away for a game, said Minoso's courage paved the way for him and the younger generation of Latino ballplayers.
"Without Minnie, without his courage to leave Cuba for the major leagues, without his willingness to accept taunts and slights, none of us would be major leaguers," he said. "... As I take the field today, a Cuban proudly wearing a White Sox jersey, I will do so thinking of Minnie. Thank you, my friend."
Minoso died March 1. He was believed to be 90.
Known as the "Cuban Comet," Minoso was part of a wave of black players who integrated the sport. In segregated America, he often couldn't stay in the same hotels or eat in the same restaurants as white teammates. And he had to put up with taunts like the time an opposing team released a black cat in front of him and called it Minnie.
"When he first arrived on the South Side in 1951 all the naysayers said he had two strikes against him: He was black and he was Latino," Mayor Rahm Emanuel told the crowd. "... He stepped up to the plate in his first game, in his first time at bat ... and he went ahead and hit a two-run homer."
Minoso also took care to acknowledge fans, never refusing an autograph.
"He not only signed the autographs, but he was very careful so that people could read his name. He was proud of the name," said former White Sox pitcher Billy Pierce.
Fighting back tears, Charlie Rice-Minoso, 26, recalled his father's less widely known side: his love of dominoes, cooking enough food for an army, watching black and white cowboy movies until dawn and his tremendous superstitions.
If the Sox were on a winning streak, Minoso would insist on sticking to the same routines, right down to wearing the exact same clothes day after day, convinced that if he altered anything the team would lose, his son said.
And then, he said, there was that smile.
"He was the most generous man with the most infectious smile that ignited a chain reaction of positive energy and joy that made you feel so special," Rice-Minoso said.
As the service concluded, an audio recording of Minoso's voice was played into a microphone. His thoughts were with his fans.
"Since I came over here in 1951, you gave me your love, your respect. ... My family and myself again thank you," he said. "I love you and God bless you"
A youth choir sang "Take Me Out to the Ball Game," as pall bearers carried Minoso's casket out of the church, before a procession that would wind past U.S. Cellular Field and old Comiskey Park's home plate.
