I'm currently participating in a Superstar 60s league, and one of my players is Mike Andrews (no card reveal, but he's performing well, so I believe it's his 1969 card). Anyway, while I was perusing through his five seasons, I noted that three of the seasons, 1968, 1969 and 1970, do not have a GB A+ reading against either LHP or RHP.
Regardless of how good or how mediocre a player is, I always thought that a GB A+ (or B+) reading showed up on the batter's card. If my memory serves me right, I believe that even a 1 hitting pitcher has a reading on 3-7.
Is this a unique circumstance? I don't believe I've ever encountered it before.
