The Mets have told the Colorado Rockies they would like to be involved with trade discussions if and when Troy Tulowitzki and Carlos Gonzalez become available, the Post's Joel Sherman reports.

Tulowitzki Writes Sherman:

But keep in mind Tulowitzki has indicated he has become frustrated playing his prime mainly in non-contention. And there is belief if he were to request a trade, ownership would strongly consider fulfilling his wishes. However, Tulowitzki has a no-trade provision, wears No. 2 in honor of Derek Jeter and is thought to be considerably more interested in being a Yankee than a Met. And Colorado already has expressed interest to the Yankees in their top pitching prospect, Luis Severino.

Plus, sources say the Cardinals -- owners of arguably the deepest farm system in the sport -- are enamored with Tulowitzki and would move significant pieces to land him. In fact, the market will be deep if Tulowitzki comes onto it, because he is viewed as one of the 10 best players in the majors.
