If you played teams sports growing up you have probably heard of what was first called the "slaughter rule" and was later changed to the "mercy rule" (even though the concept was the same) because the language police decided the second one sounded nicer and would hurt people's feeling less which I find ironic since the whole reason why the concept was invented was to protect feelings in the first place.
The idea behind this mercy/slaughter rule is that if one team is extremely better than another that the game gets called off early after a team is ahead by what is considered to be an impossible to overcome margin after a certain amount of time. The rules vary depending on the sport in question but the idea is the same. This is commonly used in youth sports and the idea is so that the kids don't get too traumatized by a horrible loss. You don't often expect it to be seen when the game in question is something that the best in the world are participating it is televised worldwide.
Yet it happened just a few days ago in the Wold Baseball Classic for the first time in the tournament's history and then again just a day later.
Japan is always considered a contender to win the entire tournament and they are the only team to have done so twice. The tournament hasn't been around very long and yet Japan has won 50% of them. Many people would just presume that USA, the creator of the sport, would dominate these games but that simply isn't the case. There are various cases that can be made for why that is but they are mostly excuses. Japan is just damn good and that is the fact of the matter. When Chinese Taipei had a game against Japan in the qualifying rounds of this tournament, nobody expected Taipei to win that game but I don't think anyone really thought that it was going to get so out of control so quickly.
Even if you don't watch baseball, you have likely heard of Ohtani or Shohei Ohtoni, who right now is considered by most to be the best player in the world and already looking like he could end up being the best player of all time.
While the first inning was rather uneventful on the part of both sides with neither scoring a run, the 2nd inning was a display of excellence that showcased why Japan is just unbelievably good.
I don't recall if it was his first at bat or not because I was only halfway watching it, but he absolutely crushed a pitch with the bases loaded to put Japan up 4-0. One would think this would be enough of an exclamation point on the game but that 4-0 lead didn't stop there. Before the 2nd inning came to a close for Japan's at bat, their squad would rotate all the way through all the rest of the batters and Ohtani ended up at bat again. In the meantime Japan had scored an additional 5 runs and the score was at 9-0. They would end up getting an additional run from Ohtani's 2nd at bat and ended the inning with a 10-0 lead.
Japan is a kind country, they tend to be a lot more polite than other nations and I am sure you have heard the stories about them and their fans cleaning up arenas before they depart for the day... but Japan wasn't going to lie down just yet.
In the following inning, I guess just to have a bit more fun, Japan put up an additional 3 points making the game 13-0
I think that maybe a decision was made in the Japan dugout at this point to ease up a bit and maybe preserve their best players, especially the pitchers which become very important later on in the tournament when competition is going to be a bit more intense.
This didn't mean they were going to give away points though and they didn't. Taipei only managed a single hit in the game and ended up with zero runs. The mercy rule was activated at the end of the 7th inning. The way the rule works in this tournament is that if a team is ahead by 10 runs or more after 10 innings the game is called off and it is over early.
Taipei isn't a terrible team as far as this tournament is concerned: you don't get invited if you are terrible. They put up a good fight against Australia losing 3-0 but that game vs Japan separated the pack a bit and kind of showed how much better Japan is than their opponents. Later on Japan would barely eek out a victory vs rival South Korea 8-6 and as i sit here typing right now Taipei is currently playing South Korea and is currently winning that game. It would be considered quite the upset if they were to pull that off but it is only inning number 3 so lets not get excited.
Now let's look at something else though. While it was likely extremely humbling for Taipei to be saved by the mercy rule themselves...the very next day Taipei trounced Czechia and had a mercy rule enacted FOR THEM as the score was 14-0 after 7 innings.
So I guess they got a little bit of vindication there and people feel better... Well, unless they are from Czechia who was eliminated from the tournament with that loss.
The field is still very much open and there is plenty of tournament remaining. The countries you would expect to be doing well are largely doing so with USA winning all of their matches, Puerto Rico doing the same, and Japan and the Dominican Republic following suit. There are some dark horses remaining such as Australia who is yet to lose and while they haven't really been tested yet, Italy is undefeated as well.
There was never really any doubt about who is going to advance in these things and the brackets are set up the way that they are so that the teams considered to be the best cannot be eliminated on their way out of the group stages. The organizers don't even pretend as though this is a totally random draw like the football World Cup is.
Right now though the game to watch is Korea vs. Taipei because it would be considered rather shameful for Korea to not make it out of the group stages since they have the 3rd largest baseball market in the world by participation and number of fans.
Just a little side note of personal experience about the mercy rule in baseball. When I was a teenager I was at a minor league or "farm league" team game and the home team was down by 11 points in the 8th. The teams were asked about if they wanted to use the mercy rule and the team that was losing declined. Therefore the game continued much to the delight of the mostly very drunk fans who hadn't gone home yet. This team went on to score 13 runs in the 9th inning, their last at bat. They won the game. So a comeback actually can happen but that instance that I was there for is probably one of the very few times that has ever happened.
