Zack Greinke's time with the Houston Astros is likely done after two-and-half seasons, which ended in two World Series appearances and one game shy of another in the pandemic-shortened 2020. 

That's not a bad run at all, to say the least, even if the Astros could not win a title with Greinke on the squad. 

The 2009 American League Cy Young Award winner is expected to sign with a National League team, per USA Today's Bob Nightengale. Greinke has a stated goal of getting to 10 home runs and 10 stolen bases in his career. 

He's said it's the only milestone he cares about. He never wanted to throw a no-hitter, because "a bunch of nonsense comes with it." But he wants to hit bombs and steal bases. 

Of course, the National League could adopt the designated hitter through a new collective bargaining agreement, which might nullify its prioritization for Greinke if he's indeed serious about getting his personal milestone.

So here is a mix of 10 possible landing spots from both leagues. When ranking these, consider Greinke's preference to play in the National League, his desire to win at age 38, and where he can be most useful. 

10. New York Yankees

Can the New York Yankees ever be ruled for any free agent, especially one as famous as Greinke?

This would seem like an odd fit on the surface. Greinke, with his history of social anxiety, has never shown much interest in the pomp and circumstance that comes with playing in New York. In addition, there have been no reports linking the 38-year-old right-hander to the Yankees.

What makes this an interesting idea is if Greinke is willing to move to the bullpen, where the Yankees could still use him in a lower profile role with fewer media obligations (especially if clubhouses are still closed). Sure, Greinke was a shell of himself at times last season with Houston, where he posted a 4.16 ERA in 171 innings and collected his fewest strikeouts per nine innings since 2005.

But when the postseason arrived, the veteran moved to the bullpen during the ALDS. Since he was struggling to eat innings but could still deliver quality pitches in spurts, he made sense for the Astros as an opener or possible long reliever.  

9. Boston Red Sox

The Boston Red Sox need starting pitching and fell short against Greinke's Astros in the ALCS last season. Any consistently competitive team should at least be interested in Greinke, so it's reasonable to think Boston could be in the mix.

The Red Sox have the money, and the need is there. They have Nathan Eovaldi and Chris Sale at the top of their rotation, which is a solid one-two punch when Sale is healthy. 

But there is a question about their No. 3 starter spot after the loss of left-hander Eduardo Rodriguez to the Detroit Tigers in free agency. The Red Sox wanted to keep Rodriguez, as evidenced by their extending him the qualifying offer and reportedly offering him a multiyear deal before he chose Detroit. 

Rodriguez signed with the Tigers for five years and $77 million for a $15.4 million annual average. 

Boston could get Greinke for around that salary figure, but for fewer years—possibly just one or two.
