Per an even older IR:
CardNum: NNO
Name: Jarrod Saltalamacchia
Team: Atlanta Braves
Note: Rookie Of The Year Contest

And the IR submitter did post to the forums: https://www.tcdb.com/Forum.cfm/Page/S/ID/1977/?MODE=VIEW&ThreadID=23923 (Which I have now moved to this set.)

And that IR submitter hasn't been on the site in over a year now...

I have a few minutes, I'll poke around a bit. Besides, I just want to avoid this trip report for a minute or two.
