Don't put yourself in the position to play in a one-game playoff. Win the fucking division.
The people who don't like the 1-game playoff are the same people who don't think winning the division is all-important.
That includes me. The Pirates were clearly more impressive than the Mets and Dodgers. They played a harder schedule, they won way more, and they won way more against good teams. Other than mysticism about divisions, there is no reason the Pirates should be "punished" with a 1-game playoff.
At the same time, I don't think a 3-game playoff solves anything, because the playoffs already go too long into the year and any extra time spent on the 3-game playoff would be better spent shortening the playoffs and layoffs.
One option would be reducing the number of divisions, so that the 2nd best record in the league (the Pirates in this case) would never be involved in the 1-game playoff. I don't care much if the lesser teams are forced into such a game, but it sucks that it happened to the Pirates.
Arrieta got calls early but by the middle innings and especially late he got the normal strike zone.
There is no "normal strike zone". Umpires can have a bigger or smaller zone than other umpires. The important thing is being consistent (same strikezone for both pitchers).
The ump in this game was surprisingly consistent. Literally every single one of Arrieta's called strikes outside the box is closer than every single one of Cole's balls outside the box... which means the strike zone was the same for both pitchers.
The mistakes the ump made were 3 balls (2 for Cole, 1 for Arrieta) that were clear strikes inside the box. Calls outside the box were consistent.
