There's always something new. I all my years of making up hypothetical plays, I never considered one in which catcher would be the fielder of consequence in a play where the runner is hit by a batted ball.

The OP, though, reminds me of the case play in which, with the runner on 1B stealing, the batter hits a roller past the mound, and with F6 and F4 both running toward 2B, the ball hits the runner as he slides in to 2B. As I recall, the ruling there is also "nothing" (since there was no play possible?).

In the 7th game of the 1955 World Series, Phil Rizzuto, running from 2B, slid into a roller toward 3B and was called out, but that was because Don Hoak was right on top of the play trying to field the ball.
