I've found seven occasions where a PR has come around to score and then batted and hit a home run. This last happened on 30 Sep 2000 Oakland vs Texas, where Ryan Christenson pinch ran for LF Ben Grieve who batted 6th in the bottom of the 7th inning, the score at the time was Oakland 15 Texas 1. Christenson cane around to score and then batted in Grieve position with the score now 20-1 and hit a 3-run home run. How is the home run credited (scored) as a PR or LF or something else since PR is not a position.
Four times the PR when out to the position of the runner he replaced, once to a different position, and twice the PR replaced all together.
