There's Chris George.

Also, who can forget Mark Kiger, the guy who made his only ML appearances in the postseason with the 2006 Athletics?

Eddie Kolb (Pitched the final game for the atrocious 1899 Cleveland Spiders)
Joe Hietpas
Roger Holt
Steve Lomasney
Jim Mahady
Charlie Faust

I'm sure there's others.

I assume he is also the only one to make his MLB debut during postseason play as well?

Bug Holliday did it before him. I remember all the discussion about this back in 2006.

With the season starting in March for some teams now, a "Mr. March" is possible as well. I don't think there is one, although Danny Young came close.
