Last year the Giants were clearly the best team in baseball. This year though, they really need to take a look at this now. Arrieta was the Cubs ONLY chance of beating the Pirates. They literally would have no chance of beating the Pirates in a series. So this one game thing has it's pros and cons.
Like I mentioned, it would have been an absolute shame if the extra team wasn't added and the Giants missed out last year. But one game is almost ridiculous. The Cubs are not nearly as deep as the Pirates, not to mention the entire regular season is made up of series, then all of a sudden it's do or die.
I'd play the Wild Card best of 3 Tuesday, Wednesday, and Thursday. It's baseball, one of the games being in a different city doesn't mean you need a break. Then start the Division Series on Saturday. Is it that ridiculous to have the Cardinals this year wait one more day to start their playoffs?
