The Houston Astros lineup is pretty much set going into Spring Training. Their rotation on the other hand is not.
The Astros have four or five pitchers battling each other for the fifth and final spot in the rotation.
One bigger concern for the Astros could be at the top of their rotation.
The NL Central is the one division in the National League where a surprise team can emerge and make a run into the playoffs.
The NL East (Phillies) and NL West (Giants) titles seem already locked and it is only day one of Spring Training, but then again, that is why they play the 162 game season.
That leaves a surprise contender from the NL Central. The Astros have a very young team that will compete every day. They have a decent rotation and good depth, but they lack a true ace up top to anchor the staff.
Here are some trade possibilities for the Astros to consider in order for them to be the surprise team out of the NL Central.
