2020 – Josh Donaldson was introduced at Target Field as a member of the Twins after finalizing the largest free-agent deal in team history, a four-year, $92 million contract shattering the previous record by $37 million.
1929 – The beginning of MLB uniform numbers. “The New York Yankees announce they will put numbers on the backs of their uniforms, becoming the first baseball team to start continuous use of the numbers. The first numbers are based on positions in the batting order; thus, Babe Ruth will wear number 3 and Lou Gehrig number 4. In a few weeks, the Cleveland Indians announce that they, too, will put numbers on the uniforms. By 1931, all American League teams will use them. It will be 1933 before all National League players are numbered.”
I think this is kind of ironic since the New York Yankees don’t wear number now.
