PHOENIX -- While Zack Greinke's no-trade clause allows him to block deals from a number of big-market teams, it does not include several clubs that hope to be contenders in 2019 and have some money to spend.
As part of Greinke's six-year, $206.5 million deal signed prior to 2016, he has a limited no-trade clause which includes the Orioles, Red Sox, Reds, Rockies, Tigers, Yankees, Athletics, Padres, Giants, Cardinals, Blue Jays, Angels, Dodgers, Twins and Phillies.
The list of teams was first reported by The Athletic and later confirmed by a baseball source.
That leaves teams such as the Nationals, Braves, Astros and Brewers as possible trade partners for the D-backs should they decide to move Greinke.
All four teams are known to be interested in acquiring pitching this winter, and all have the resources to do so in terms of young talent to trade and payroll flexibility.

While the D-backs have said they are open to listening to trade offers on any of their players, including Greinke and first baseman Paul Goldschmidt, no deals appear imminent and one or both could certainly stay in Arizona.
A Goldschmidt trade seems more likely than a Greinke deal given their contract situations.
The advantage for the D-backs in moving Goldschmidt is that he is entering the final year of his contract. If Arizona doesn't re-sign him and ends up making him a qualifying offer next year, it would receive a Draft pick in return.
Coming off another stellar season, the list of teams that would want him in their lineup is long, but with Goldschmidt slated to make $14.5 million next year, the D-backs are under no financial pressure to deal him. So, if Arizona doesn't get the package it wants in return, the D-backs will hang onto him.
Team officials have also made it clear that the process with Goldschmidt will not drag on all winter.

Greinke's no-trade clause, as well as the around $100 million he is owed over the next three years, makes dealing him far more complicated.
Dealing Greinke would give Arizona tremendous payroll flexibility going forward as it looks to retool. While it's been speculated that the D-backs would have to eat some of Greinke's salary to trade him, the organization appears confident it will not need to.
And any talk of attaching Goldschmidt to a Greinke trade simply so the other team will pick up Greinke's entire contract is a non-starter for the D-backs.
Again, there is no urgency for Arizona to deal either player. The organization has said it has no intention of undertaking a massive rebuild even with the expected losses of lefty Patrick Corbin and outfielder A.J. Pollock to free agency.
Instead, the D-backs would like to find a way to still be competitive in 2019 while continuing to build its Minor League prospect base.
