CHICAGO — It was 21 years ago this October when Ozzie Guillén did something we thought was unachievable: He led the Chicago White Sox to a World Series championship.And it was just before 6 p.m. on Saturday when Guillén did something I thought was impossible in the year 2026: He got White Sox fans to cheer for chairman Jerry Reinsdorf.I hope Pope Leo was watching, because Ozzie’s sainthood case now has its two miracles. Maybe Leo, who was there in person for the 2005 World Series, can make an exception with the whole “being dead” part of that deal.At the beginning of his speech on the field the night of his jersey number retirement, Guillén thanked the White Sox owner, whom he has often said he loves more than his own father because Reinsdorf gave him money and a few jobs. Out of respect, the fans didn’t boo when Reinsdorf’s name was mentioned, and when Guillén implored them to cheer, they did.Ozzie Guillén speaks to the sold-out crowd Saturday during his number retirement ceremony. (Jon Greenberg / The Athletic)Yes, on a warm summer night on the South Side, there was love and respect in the air. Even for Jerry. And after four straight losses, the Sox won, 6-3, to pad their lead in the AL Central.Two-and-a-half hours before Guillén spoke, I walked through the parking lot and the line of fans waiting to get in — and snag a giveaway No. 13 jersey — was like nothing I’ve seen here.It was Ozziepalooza. It was Oz Fest. It was well-deserved.The best player in White Sox history was Guillén’s teammate, Frank Thomas, who, sadly, was a no-show Saturday.The most loved player in the last two decades? Easily, it’s “The Captain” Paul Konerko, who showed up, spoke and got raucous applause.The best Venezuelan player in White Sox history? Guillén’s idol, Luis Aparicio.But over the last 40 years, no one has represented the Sox more authentically than Guillén.The White Sox are a loud, messy, colorful, imperfect organization, and so is Ozzie. He had a glove that made him a three-time All-Star, a brain that made him a World Series-winning manager and a mouth that made him a true South Sider.
