The Houston Astros may be the reigning World Series champions, but that doesn't mean they're satisfied with just one ring on their fingers. 

Houston has spent the entire offseason locking up even more talent to help them make another run in 2018, but none are as important as this move. 

​​The Astros ​acquired Pirates ace Gerrit Cole in a move that sent top prospects Joe Musgrove and Colin Moran to Pittsburgh. 

With Cole, the team now has a rotation that consists of Dallas Keuchel, Justin Verlander, Lance McCullers, and Gerrit Cole. That'll be pretty tough to be in any situation, as each pitcher has ace potential. 

Astros fans should be pumped about the deal, and if this tweet from Alex Bregman is any indication, they are. 

That is one excited man right there. 

The Astros are going into next season with one of the best rotations AND one of the most potent lineups. It's gonna be quite the season. ​​
