April 9, 1965: Astrodome opens when the Astros face the Yankees in an exhibition game with President Johnson and Texas Gov. John Connally in attendance.

July 9, 1968: Astros play host to the 39th All-Star game, with the NL beating the AL, 1-0. It's the first All-Star Game played indoors and on artificial turf. Willie Mays scored the only run, in the first inning.

Oct. 2, 1976: On the final day of the regular season, J.R. Richard throws a complete-game, four-hitter and strikes out 13 Giants to become only the second Astros pitcher to win 20 games in a season, joining Larry Dierker (1969). He finished 20-15, with a 2.75 ERA.

Oct. 10, 1980: Denny Walling's 11th-inning sacrifice fly scores Rafael Landestoy with the winning run in a 1-0 win over the Phillies in Game 3 of the NLCS.
