If the Mets choose to move Jenrry Mejia to the bullpen, then it doesn't mean Daisuke Matsuzaka, who lost out on the fifth spot in the rotation this spring, would move into the rotation, per The Star-Ledger.
"We haven’t even talked about the first part seriously yet, but what happens after, it wouldn’t necessarily be Daisuke gets it," Mets assistant general manager John Ricco said.
Ricco said it is more like the Mets would turn to Rafael Montero or Jacob deGrom, who are both in the rotation at Triple-A Las Vegas, over Matsuzaka.
