Patrick,
I'm sure you checked Baseball Resource, as I just did.
No MacConachie at all.
But, I dropped the "a" as a possible misspelling and came up with this fellow:

As you stated probably didn't make roster, but played for lower Class D Carolina Assoc.
No first name, but if you go 7 for 62, you probably won't be remembered
