The big difference is that Campeneris did his feat (50 years ago) all in one game -- playing all (then) nine positions in each of the nine innings. And...it was in a real game that counted, not Spring Training. At the time, Campenris was a shortstop for the Kansas City A's, before owner Charley Finley moved them to Oakland. Campy is still with the team, as a coach.
Here's a very nice 3-1/2 minute video that the MLB Network aired about Bert Campeneris's odd, wonderful stunt of something that had never before occurred in a major league baseball game, and hasn't since.
