Former Cub and longtime Cardinals outfielder Lou Brock died Sunday afternoon. He was 81 years old.
According to the St. Louis Post Dispatch, Brock fought through a number of medical conditions in recent years.
Brock was part of one of the most lopsided trades in baseball history. He came up with the Cubs in 1961, playing in Chicago into the start of the 1964 season. That June, the Cubs sent him to the rival Cardinals in a trade that sent starting pitcher Ernie Broglio to the Cubs.
While Broglio, who posted a 5.40 ERA in 59 appearances with the Cubs, was out of baseball after 1966 at age 31, Brock put together a Hall of Fame career in St. Louis, making six All-Star teams and winning two World Series, playing through 1979.
The Cubs held a moment of silence for Brock ahead of Sunday night's game against the Cardinals.
