I'm feeling better already!
Here's a tricky one, though, but may be the same answer actually:
Throw in from Left field for a potential play at home. Catcher moves out about ten feet from home plate toward the throw, conceding the run. Baserunner on second is attempting to advance to third on the throw home. Ball takes a good hop right to the catcher's waist. If he fields it cleanly and makes a good throw to third, the runner will be out easily. However, it bounces away from the catcher and the runner is safe at third. Is this an error? If so, who is charged with the error? Thanks!
