(The first time, in 40 years, that I ever got a free baseball at a game!) I noticed that the ball had Bud Selig's signature on it, but the word "PRACTICE" was printed, in small lettering, under the MLB logo. I wasn't aware that they did this, but I suppose it makes sense. It allows them to differentiate actual game-used balls from those used in the bullpen or in batting practice. I assume, then, that the PRACTICE ball has less value. I'm surprised that he'd go to the effort to get non-game balls. He must figure that quantity will make up for quality. Or something. I no longer really understand the collector market, if I ever did. his collector market isn't about worth anyway. From what I recall from his blog some teams are stingier than others, some mark them differently. It's kind of interesting how these balls get around though. You can find All-Star leftover balls among random teams BP workouts.
