Great work on this database!
One thing I noticed is Bryn Smith is on Baltimore for 1979 and '80 when he should be with Montreal. It is true he began his professional career with the O's, but they traded him to the Expos in 1977.
"December 7, 1977: Traded by the Baltimore Orioles with Rudy May and Randy Miller to the Montreal Expos for Don Stanhouse, Joe Kerrigan, and Gary Roenicke."
His ID is smithbr01
