In addition, the Mets hope to add a starting pitcher, “probably on a minor-league contract,” to compete for the final spot in the rotation, according to Sandy Alderson (Rubin, Jan. 7). They have reportedly shown interest Jerome Williams (DiComo, Dec. 7), Bruce Chen, John Lannan, Paul Maholm (Heyman, Dec. 10), Freddy Garcia (Puma, Dec. 10, Rubin, Jan 10) and Daisuke Matsuzaka.
In the opinion of ESPN New York's Adam Rubin, Garcia makes the most sense because he can transition to the bullpen when Noah Syndergaard is inevitably promoted from Triple-A during mid-summer.
The Mets were very pleased with the progress Jenrry Mejia showed in his brief stint last summer. I've heard they view him solely as a starter now, and are looking for him to earn the final spot in the rotation. However, they are very aware of past injuries, so they are looking for insurance for Mejia on the free agent market, while also seeking depth for the entire rotation, because they don't have much to fall back.
The arms they've been linked to this winter make sense for what they're seeking, especially Garcia, who could join Carlos Torres in a swing-man role (spot starter and reliever). But, they should also be interested in bringing back Aaron Harang or taking a look at someone like Tommy Hanson, since both could thrive in the big ballparks in the NL East.
Interestingly enough, there has been some buzz about Rafael Montero or Jacob deGrom pushing to make the team out of camp. It sounds as though they could be secondary options to Mejia as well, since they are both major-league ready.
