The biggest Mets Opening Day roster decisions to follow this spring
2) Could Peterson and Megill be reliable in the Mets bullpen?
Here is a tricky one. Peterson worked as a starter and reliever last year putting similar ratios in both roles. In the case of Megill, he was better as a starter but the sample is too small to determine his efficiency in those roles.
Megill was the opening day starter in 2022 and displayed an arsenal of arm power, with a fastball that hit 99 MPH several times throughout the year before going on the disabled list, from which he returned as a reliever.
Peterson, for his part, turned out to be quite efficient in 2022 thanks to the change he made by decreasing the use of his sinker and considerably increasing his slider to which he was hit just for an average of .175.
The case for both being in the Mets bullpen depends more on the rotation. The Mets have a lot of question marks given the age of Verlander and Scherzer, Senga's workload, and Carrasco's injury proneness.
For this reason, the Mets should rely on Peterson and Megill as long relievers with options to start games if one of these pitchers in the rotation needs rest or in the event of an injury. But the team will have to maintain a system where both arms can be fresh and available to start games in those cases since a reliever's warmup is not the same as a starter.
