The Mets wasted no time in naming Mike Pelfrey the team's opening day starter with Johan Santana expected to begin the season on the disabled list. Manager Terry Collins made the announcement Wednesday to a group of Queens schoolchildren at Citi Field, less than a month before spring training starts. He then elaborated to reporters. ?He deserves it. He earned it. He should have made the All-Star team last year. Right now, I think Mike Pelfrey should be the No. 1 guy on our staff at this moment.?
