The New York Mets are barreling toward the final 13 games with a rotation that, outside a few reliable arms, has routinely put them at a disadvantage. There is a clear route the Mets could follow, one that could finally turn this rotation into an asset. The Mets have 13 games in 15 days to end the season, and they can’t afford to waste starts from shaky arms. That’s nine of the remaining 13 games in the hands of pitchers who give the Amazins a chance to compete. If the Mets lean on Peterson, Sproat, and McLean as planned, they could turn the final 13 games into a decisive stretch.
