Well, as coincidence would have it, my catcher went after a foul pop in no man's land in front of the 3rd base dugout a few hours ago and suffered a mild concussion when his face hit the leg of the 3rd baseman who was also going all out for the ball. I shudder to think how much worse it could have been had he not kept his mask on, even going after pop ups, as I have told him to do!
