As TT said, it could have been the 4 hitter instead of the 3 hitter, but otherwise that's exactly what happened. The runners beforehand reached base and then Sandberg had a sac bunt laid down to move the runners over. If there was another reason for doing it, I haven't heard Ryno give why. But seriously, take Sandberg's name out of the equation. Wouldn't you think something unusual happened here? A missed sign? An attempt at a bunt base hit? There's plenty of explanations that make more sense than "Sandberg was giving up an out to move his base runners over with his 4 hitter so his 5 hitter could drive them in". Why would you take Sandberg's name out of the equation? His stated philosophies and managerial record show that "giving up an out to move his baserunners over with his 4 hitters so his 5 hitter could drive them in" was exactly what he was doing.
