Koufax became the sixth pitcher of the modern era, and eighth overall, to throw a perfect game.

The game was also notable for the high quality of the performance by the opposing pitcher, Bob Hendley of the Cubs.

[1] Koufax retired the first batter he faced, Donald Young, a late season call-up, on a pop-up on the second pitch of the game.

[1] In the second inning, Ron Santo fouled out to catcher Jeff Torborg, Ernie Banks struck out on a forkball, and Byron Browne, during his first major league at-bat, lined out to center fielder Willie Davis.

[1] In the top half of the fifth inning, the Cubs went three up, three down with Santo flying out, Banks striking out for the second time in the game, and Browne grounding out.

Ron Fairly dropped a sacrifice bunt that Hendley bobbled, leaving his only play at first base.

The Cubs' catcher Krug threw the ball over Santo's head and into left field, which allowed Johnson to score.

Krug grounded the ball to shortstop Maury Wills, who threw it in the dirt to first baseman Wes Parker.

Kessinger hit a dribbler down the third base line, but Jim Gilliam was playing shallow (to guard against the bunt) and threw him out by half a step.

At the start of the seventh inning, Koufax threw one pitch that sailed past Young and went all the way to the backstop.

During the bottom of the seventh inning, Johnson broke up Hendley's no-hitter with a bloop hit behind the second baseman.

[1] Until Cole Hamels of the Philadelphia Phillies no-hit the Cubs on July 25, 2015, the perfect game had been the last no-hitter to be pitched against them.
