New York Mets starter Sean Manaea is expected to begin the season on the injured list because of a right oblique strain. Manaea said Monday that he had been dealing with the issue since getting to spring training. He says it never got worse but never improved. The left-hander was the Mets’ top starter last season and then got a $75 million, three-year contract. He had an MRI over the weekend and won’t throw for two to three weeks. Manager Carlos Mendoza also said infielder Nick Madrigal fractured his non-throwing shoulder in a spring training game Sunday.
