Probably because we never watch the computer play each other....
But this is what GoReds and I saw. I think the computer was trying to go back to tag up and there was a doink but the batter made it to first and the runner from first didnt get back in time so he just stopped there a few steps from the bag. The catcher has the ball i think but just held it nothing happened afterwards. I know its a CPU vs CPU glitch but a glitch none-the-less.
I've seen this same thing twice when playing against the computer. I've seen it happen at first base, and I've also seen a runner just stop inbetween third and home....I think the bop definitely has something to do with it.
Computer logic at it's finest... Let me make sure I have it right - the runner between first and second was running back on a flyball but there was a BOP, correct? And now he's not running to second, where he would be safe?
I am pretty sure on that. GoReds was watching when it happened.... he will confirm this.
