Honestly, they are a good story. Part of me is rooting for them to just keep winning and bury the Cubs (even more than they are already buried). I can't say the Cubs don't deserve it.
That is pretty standard now. Everything is tracked pitch by pitch in the Game changer app and there are strict rules by age on the number of pitches allowed, combined with required rest based on how many pitches were thrown.
It's crazy to think, but the Brewers might soon be nearly out of reach. 4 games is do-able, but if they drop a few more games over the next week, does anyone really think the Cubs can make up 6 games in a month and a half?
Other teams go to the pen and immediately shut the Cubs down with a series of unknown relievers.
The Cubs go to the pen and immediately undo all the good work the starter did.
