Wasn't that when he was still with the Red Sox? It would still qualify as a no hitter. You should remember when six Astro pitchers combined for a no-hitter against the Yankees.

The game was on June 23, 1917, when Ruth was still with the Red Sox.

Many sources include it in lists of perfect games, but I believe that official recognition was removed. It still qualifies as a no-hitter, but I don't know whether the credit goes to Shore alone or it is considered a Ruth-Shore no-hitter, in other words, a no-hitter by multiple pitchers.

As long as I can remember, a fumble "which prolongs the time at bat of a batter" has been an error. I would be interested to know when that rule was established.
