The newspaper reported that it has identified the slugger as being one of the new investors in a bid by business tycoon Jeff Cooper to bring an MLS team to the Midwest city.
Cooper is the leader of an effort to bring a soccer team to a proposed stadium in suburban Collinsville.
"I am very proud and excited to join the effort to bring Major League Soccer to the St. Louis area," the 28-year-old Pujols said in a statement. "This means a lot to me and my family, as we all love soccer and we believe in MLS."
"Adding Albert to the group is a big step forward along the city's path to a soccer team," Cooper said.
He added that other members of his expanded investment group will be announced later.
