Well, John Maine didn’t last long as a Met, hitting the disabled list just days after his May 1 debut. His spot was grabbed by Bartolome Fortunato, back in No. 43 for the first time since 2004. Things got hairier on Saturday, when sadsack starter Victor Zambrano 38 walked off the field and into a season- and possibly, Met-career-ending elbow injury. Maine’s start, and Zambrano’s space on the roster, was covered, barely adequately, by clownish righthander Jose Lima, and with Bannister and Maine still missing, more changes are certain to come. Lima by the way became the 29th guy to wear No. 17 for the Mets — only No. 6 has been issued more often. (34 has also been worn by 29 guys)
