Ken Rosenthal of The Athletic reported Monday that the Diamondbacks are in a "transition" with Patrick Corbin and A.J. Pollock due for free agency. Greinke and Paul Goldschmidt may be available in trade discussions to help expedite that process.
Greinke, 35, went 15-11 with a 3.21 ERA and 1.08 WHIP last season. He will make $34.5 million in 2019, along with $35 million salaries in 2020 and 2021. It's unclear how much of the contract the Diamondbacks would be willing to eat in trade negotiations.
Teams may wind up waiting to see where Corbin signs before pursuing Greinke, who is older and will cost prospects. Dallas Keuchel is also a free agent and should see numerous bidders across the league.
A team like the New York Yankees could focus on landing Corbin or Keuchel before making a move for a Greinke or Corey Kluber, the other major pitching name expected to be bandied about on the trade market this winter.
The Yankees are one of only a select few teams that have the combination of young players the D-backs may want and the financial wherewithal to absorb most of Greinke's contract.
They are also expected to be major players in the pitching acquisition market. A need to improve their staff, whose starters put up a middling 4.05 ERA in 2018 (second-worst among playoff teams), could force their hand if they miss out on the big-name free agents, or the Yankees could land a free-agent arm and pull off a blockbuster trade.
Greinke has been among the most consistent pitchers in baseball throughout his career. He has recorded at least two wins above replacement every year since 2007, per FanGraphs.
