In his third ML start for the White Sox, Robertson was perfect. On April 30, 1922,
at Detroit, he beat the Tigers 2-0 with the sixth perfect game in ML history. A diving
foul-line catch by left fielder
Johnny Mostil preserved the win. His subsequent career
was a disappointment: he nursed a sore arm through six more seasons, never winning
more than he lost.
