Hi David. No, Matt wasn't included. He did play a bit in the regular 1975 season, but did not play in the playoffs against the Red Sox and I could find no indication that he was on the playoff roster. Let me step back and say that I thought finding the playoff/series rosters would be much easier, but it wasn't. In 71, they used the whole bench so that was easy from just the boxscores. I found a nice blog describing the debate on who to add and not to add for 72 and 73 playoff rosters, but 74 was a bit tougher (the series only went 5 and not everyone played) and of course 75 not everyone played. To the best of my knowledge through articles, film, blogs, etc, I believe I got everyone...at least I hope I did
