The Mets have made Bartolo Colon available in trades, ESPN New York’s Adam Rubin reports. The team isn’t thought to be seriously negotiating a Colon trade at this time, though a Major League source thinks the Mets will start hearing more offers on the veteran right-hander over the next week.

It was reported last week that the Mets were listening to offers for the 41-year-old Colon, who fits as a trade chip given his contract ($3.75MM remaining this season and $11MM in 2015) and the fact that New York has the young pitching depth to take Colon’s spot in the rotation both this season and next. The Mets could wait until past the July 31st deadline to move Colon and “it is not a foregone conclusion that he will be dealt” at all, Rubin writes.

The Mets’ deadline needs include a power-hitting left fielder and a shortstop who can supplant Ruben Tejada, Rubin reports, though these pieces wouldn’t necessarily come from a Colon trade. (While Colon is still pitching effectively, his age will likely prevent the Mets from landing a true impact young player in return.) The Diamondbacks and Cubs stand out as teams with a possible surplus at shortstop, and the Mets have been connected to Didi Gregorius in the past, though Rubin hears that Tony La Russa is still evaluating Arizona’s roster and may wait until the offseason for major moves.

As for the Cubs, the addition of Addison Russell to an organization that already has Starlin Castro in the bigs and star prospect Javier Baez at Triple-A would seem to make them trade partners for the Mets as well. Rubin says that Baez “is believed to be a more realistic target” for the Mets, though it would take a major deal to get Chicago to part with a player who is a consensus top-10 prospect in baseball, despite Baez’s underwhelming Triple-A numbers this season.

To create room in the outfield, the Mets are trying to find trades for Chris Young and Eric Young Jr. Neither player is enjoying a particularly strong season, though Young Jr. will be more attractive to other teams due to his speed (25-for-28 in steals) and two remaining years of team control, whereas Chris Young is owed over $3MM for the rest of the year.
