This has been one of the most memorable regular seasons I've ever watched, there has been so many incredible moments, including another one yesterday, coming down from 7-1, against a playoff team, with almost all backups in, capped off by a guy making his 2018 debut in Brandon Phillips hitting a game winning home run.
I think almost everyone will agree here that the best moment of the season was the come from behind win against the Yankees, which capped of a 4 game sweep and essentially burying the Yankees.
But aside from that, I think I would have to go with Mookie Betts 13 pitch grand slam against the Blue Jays. That is probably the only time I've seen a home run in the 4th inning feel like a walk off. Everything about that AB was crazy, 13 pitches, Smoak misplaying a popup he probably should've caught, and of course I loved Mookie's reaction after he hit the ball.
Any other ones you guys would like to add? I'm sure there is plenty.
