June 25, 1998
#OTD in @chicagocubs history ▸ Sammy Sosa breaks the major league record for homers in a single month when he hits his 19th dinger in June, a seventh inning solo shot off Brian Moehler in the Cubs’ 6-4 loss to the @detroittigers at Tiger Stadium.
The Cubs’ slugger surpasses the mark set by Rudy York, the Tigers’ rookie catcher. York finished with 18 after homering twice on the last day of August 1937 at the same ballpark (when it was known as Navin Field).
Five (5) days later, on June 30th, Sosa will hit #20 setting the new @mlb record.
