Roger Connor becomes the first major leaguer to hit a grand slam

At Haymakers’ Grounds, future Hall of Fame first baseman Roger Connor becomes the first major leaguer to hit a grand slam, giving the Troy Trojans a 7-4 walk-off victory over the Worcester Ruby Legs. The 23 year-old Waterbury, CT native’s sayonara slam, a home run which wins a game when a team is down by three runs in the bottom of the final inning, comes with two outs.
