As a tall lefty, I ended up playing a lot of first base in my short-lived baseball heyday. It was a fun position, providing plenty of opportunities to end an inning by interrupting a ball bound for the dirt or the chain-link fence behind me.
It also allowed a chance to play sports tattletale on the opponents who didn't have a firm grasp on the rules. Yes, the smug satisfaction gained by tagging out a runner who had made the slightest turn toward second after running through first tasted just as good as the postgame Star Crunch.
It's not every day that you see a Little League mistake like that being made in the major leagues, but it does happen to the best of us. No word on if Santana had to run a few laps around the far end of the concession stand to make up for it.
