Another name to keep an eye on is Mickey Callaway, the Cleveland Indians' pitching coach. The Phillies are "taking a close look" at him, per ESPN's Buster Olney.
Callaway, 42, has been Cleveland's pitching coach since 2013, a period during which the Indians have had one of the best staffs in baseball. Over that span, Cleveland has posted a team ERA of 3.65, which is lowest in the American League by a significant margin (the Rays are next at 3.84) and fourth-lowest in the majors.
Let's be real, though, that has much more to do with Corey Kluber, Carlos Carrasco and an elite bullpen. On the flip side, guys like Mike Clevinger, Trevor Bauer, Josh Tomlin and Danny Salazar have shown some improvement through the years, which reflects well on Callaway.
Before working his way through the coaching ranks in Cleveland's farm system, Callaway pitched in the majors from 1999 to 2004 with the Rays, Angels and Rangers.
Callaway's offseason began Thursday, the day after the Indians were shockingly eliminated from the playoffs by the Yankees after building a commanding 2-0 series lead.
