Eovaldi's performance in Game 3 was magnificent, but I don't see how it puts him with Price's 2 games.
It was just the luck of the draw, mind you, that Eovaldi only pitched significant innings in one game.
No problem with bringing Kimbrel in. I think there are several counterpoints. One is that the Red Sox had just proven you can score 5 runs in an inning. The second is that Kimbrel has shown that he will get you the 3 outs, even if it can be messy. Third is that if you put Brasier in you're probably going to have Kimbrel warming up in case there's trouble. If Brasier gives up a couple of baserunners you probably bring Kimbrel in. Then you've used both of them.
