The Red Sox sure are burning a lot of talent here. Miller is quite good and under control for three years after this one, but giving up a long-term regular for a left-handed reliever is quite a loss of value. Mayer is currently on the shelf with an arm injury and might not be much of a factor this year, but he should be the Giants’ second baseman next year and he remains very much an option at short if the club could find a taker for Willy Adames. Miller’s fantasy value disappears with the deal, since he won’t be a candidate for saves in Boston. With the Giants shedding both he and Caleb Kilian, Dylan Smith is probably their favorite for saves at the moment.
