A trade of Noah Syndergaard this month is possible -- if a heavy price is paid.

While the Mets aren’t soliciting offers for Syndergaard, multiple teams have contacted them to express interest, sources say. The cost for the right-hander would have to be high for the Mets to consider trading him.

The Brewers are among the teams monitoring Syndergaard and fellow starter Zack Wheeler, sources said. The Mets, with the National League’s second-worst record, are viewed by the industry as a clear seller in advance of the July 31 Trade Deadline.

First-year general manager Brodie Van Wagenen is likely to move Wheeler this month, as Wheeler is on an expiring contract. Syndergaard, who won’t be eligible for free agency until after the 2021 season, is a less obvious trade candidate among Mets starters.
