According to Jon Morosi of MLB Network, the Phillies have expressed interest in acquiring Edwin Diaz from the Mariners and are one of the teams interested in free agent left-hander Andrew Miller.

The Phillies are in desperate need of back-end bullpen help, with Seranthony Dominguez leading the team with 16 saves last season.  Adding arms like Diaz or Miller would give the team some more depth in the later innings of games.

Diaz, 24, might be tough to pry away from Seattle, ESPN's Buster Olney reports that even though the Mariners are having pretty much a fire sale, he and outfielder Mitch Haniger are just about "untouchable."

The 2018 reliever of the year notched a league-best 57 saves with a 1.96 ERA, 0.79 WHIP and 124/17 K/BB ratio over 73 1/3 innings.

As for Miller, 33, he had a rough, injury-plagued, 2018 season with a 4.24 ERA, 1.38 WHIP and 45/16 K/BB ratio in 34 innings of work. Miller missed three months this season with three separate disabled list stints due to knee, hamstring and shoulder injuries but is expected to be at full strengths for spring training.
