"Last Pitcher to Get a Hit Before DH Rule - 10/4/1972"

I sent a request to Larry Gowell asking him to tell the story on a baseball about being the last pitcher to get a hit in the AL before the designated hitter rule came in to effect and this is what I got:

"It was the top of the third, Jim Lonborg on the mound. I hit a 3-2 fastball down the line for a double. Yankee Stadium."

If you are not familiar with the event, here is some more info.
