“I only have one superstition: I make sure to touch all the bases when I hit a home run.”
As quoted in Baseball's Greatest Quotes (1982) by Kevin Nelson; reproduced in "Morning Briefing: Babe Ruth Was Not a Superstitious Man, Except on 714 Occasions," in The Los Angeles Times (March 1, 1982), p. D2
Unsourced variants:
Just one.Whenever I hit a home run, I make certain I touch all four bases.
I have only one superstition. I touch all the bases when I hit a home run.
“I handled 30 balls in the outfield and never made an error or allowed a man to take an extra base.”
This is the Truth! (1949)
Context: I went out and played my heart out against Cincinnati. I set a record that stills stands for the most hits in a Series, though it has been tied, I think. I made 13 hits, but after all the trouble came out they took one away from me. Maurice Rath went over in the hole and knocked down a hot grounder, but he couldn't make a throw on it. They scored it a hit then, but changed it later. I led both teams in hitting with.375. I hit the only home run of the Series, off Hod Eller in the last game. I came all the way home from first on a single and scored the winning run in that 5-4 game. I handled 30 balls in the outfield and never made an error or allowed a man to take an extra base.

Context: The 100 grand right fielder revealed that Danny Murtaugh once fined him $650 when he did not run after hitting a ball to the shortstop. He never explained how Murtaugh reached the $650 figure. "I hit the ball and I slip at home plate and they fine me $650. First time up I hit a homer one-handed. I just limped around the bases."
