From beat writer Jack Magruder of FOX Sports Arizona …
Harkey had been serving as the Yankees’ bullpen coach since 2008. He was a first-round pick of the Chicago Cubs in the 1987 MLB Amateur Draft and enjoyed an eight-year career at the major league level.
The Diamondbacks hired former Cardinals pitching coach Dave Duncan earlier this month to function as a special coaching assistant. Duncan will presumably work closely with Harkey this year in Arizona.
The Marlins designated utilityman Derek Dietrich for assignment, Clark Spencer of the Miami Herald reports. This comes amid a flurry of moves on Tuesday night as teams prepare their rosters ahead of the Rule 5 draft next month.
Dietrich, 29, is coming off another strong season in which he hit .265/.330/.421 with 16 home runs, 45 RBI, and 72 runs scored in 551 plate appearances. He played all over the diamond, spending most of his time in left field and at first base. Dietrich also played some second base, third base, and right field.
Dietrich is entering his third of four years of arbitration eligibility. He earned $2.9 million this past season and MLB Trade Rumors projects him to earn $4.8 million in 2019. Cutting Dietrich represents a bit more than 4 million in savings for the rebuilding and perennially small-market Marlins. Dietrich should draw some interest, so the Marlins could end up trading him rather soon.
Wonder how J.T. Realmuto, now the longest-tenured Marlin, is feeling right about now.
