Let's go and give longtime relief pitcher Jack Aker a "missing" card in the 1975 set.
Take a look at the card I created:
For the 1974 season, his last as a Major League player, Aker appeared in 41 games for both the Atlanta Braves and New York Mets.
He posted a record of 2-2 with a couple of saves and a 3.57 earned run average, all out of the 'pen.
As a matter of fact, in his entire 11 year career he never started a
single game, appearing in a total of 495 games in relief, posting a
(then) very respectable 124 saves, including 32 in 1966 alone when he
had his best season in the big leagues for the
Kansas City Athletics, going 8-4 with a 1.99 ERA to go along with those
league-leading saves.
Between 1964 and 1974 he'd suit up for the Athletics, Pilots,
Yankees, Cubs, Braves and Mets, finishing with a 47-45 record with a
nice 3.28 ERA and 404 strikeouts over 746 innings of work in 495
appearances.
