Roger Clemens came back to Yankee Stadium on Saturday, and so did the questions about his bat-throwing incident with Mike Piazza in the World Series 25 years earlier.

In Game 2 of the 2000 World Series, New York Yankees starting pitcher Roger Clemens threw a shard of a broken bat in the direction of New York Mets catcher Mike Piazza, who had just broken his lumber while trying to fight off an inside pitch that dribbled foul.

Two and a half decades later, Roger Clemens’ broken bat throw at Mike Piazza is still a defining moment of the Subway Series rivalry.
