1 inning major league player

Here is Harrington's story according to wikipedia.

His MLB appearance came on July 10, 1963, at Connie Mack Stadium, when he was called upon to pinch run following first baseman Roy Sievers' single; it was the eighth inning and the Phils led the San Francisco Giants, 10–2. Harrington advanced to second base one out later, following Don Hoak's single. But the inning ended when Clay Dalrymple grounded into a double play.[3] Harrington did not stay in the game on defense, as veteran Frank Torre took Sievers' post at first base in the ninth.

However I first recall reading about this in a book about Gene Mauch. In that book the story was Mauch used Harrington as a pinch runner and he was either thrown out stealing or was thrown out going first to third. Mauch was pissed. He never liked rookies ( he traded F. Jenkins to the Cubs for two older pitchers Larry Jackson and Bob Buhl) and promptly sent him back to the minors, never to be seen in the majors again!
