The passing of Lou Brock on Sunday marked another somber occasion for a sport still in mourning over the recent death of one of Brock's fellow Hall of Famers.
Brock's death came only days after the passing of Tom Seaver, an MLB legend and contemporary of Brock in the 1960s and 70s.
Brock, who retired as MLB's all-time leader in steals, was an iconic figure as the leader of the stolen base revolution of his era. His overtaking of the controversial Ty Cobb as the league's steals king also held enormous symbolic value and came only three years after Hank Aaron surpassed Babe Ruth as all-time home run leader.
Players, celebrities, journalists, fans and prominent people from all walks of life weighed in on social media to pay tribute to Brock.
Several current and former Cardinals players were among those to offer condolences.
Former Cardinals slugger Albert Pujols said Brock was "one of the finest men I have ever known."
