Bregman woud be a surprise. He's only been a .799 over the past 6 years, In order to reach .800, I think he'd need about an .846 the rest of the way.
Marte has an .849 over the past 6, and would have to average an .863. So possible for both, but less than likely.
But more importantly, the .846 and .863 only get them back to being a good player, not great players.
