Here's a "missing" 1973 card for pitcher John Cumberland of the St. Louis Cardinals:
After a very nice 1971 season with the San Francisco Giants which saw him post a 9-6 record with a 2.92 E.R.A. and two shutouts in 45 games and 185 innings, Cumberland started the 1972 season 0-4 with a bloated 8.64 E.R.A., finding himself traded to the Cardinals for a minor league player on June 16th.
The change of scenery didn't exactly help, as he went on to a 1-1 record with a 6.65 earned run average over 14 games.
All told he went 1-5 with a 7.71 E.R.A. over 23 games and 46.2 innings of work.
He actually didn't appear in a Major League game in 1973, but came back for 17 appearances in 1974 with the California Angels, fairing a bit better with an 0-1 record and 3.74 E.R.A. over 21.2 innings, his last on the big league level.
For his career, Cumberland went 15-16 with a 3.82 earned run average over 110 appearances, 36 of which were starts.
