Baseball, am I right? The cause of yesterday's brawl between Mexico and Canada is being laid at the feet of the tournament's tie-breaking procedure, specifically run differential. Because of the rules, as Canada manager Ernie Whitt said, the game is always played as though it's 0-0. So when Canada was bunting with a 9-3 lead, it wasn't to run up the score or shame Mexico, it was to protect against any kind of backdoor elimination by way of a losing tiebreaker. Which is a fairly believable prospect since only the top two teams from each pool advance and Italy had previously thumped Canada 14-4. Heading into today's 4 p.m. game both Canada and the United States are at 1-1 and the winner will advance along with Italy (2-1), but things could have gotten really dicey if the United States had lost to Italy last night. There could have been a three-way tie for the last spot in Pool D, with all teams at 1-2 if the U.S. were to beat Canada.
