At the same time though, you have to remember they did all of the scoring today against a very good Estrada and Osuna. Don't know why some think Floyd or Grilli would have fared a whole lot better. The only argument is they would have had a clean inning to work with. Imo this point is moot when you consider how much better Osuna is AND the fact that he is equally effective even with runners on base. The Boston offence is very hard to shut down and can erupt at any point just as KC's did in the playoffs vs Price. In hindsight, we probably lose this one if we send out Floyd or Grilli.
Also statistics can be a little tricky to use sometimes. It's not as straightforward as just looking at their last 22 games and seeing how many times they scored 4 runs (btw I hope you searched for 4 or more runs), b/c you can easily turn around and say Boston scores 5.89 runs per game on average so it would be no surprise if they score another 4-5 runs.
