Since this year is nearly over, here are the under-Age-30 candidates from this year's roster plus OKC for next year.
Personally, looking at this list, I feel a bit better about the Astros than the current pain of watching in 2013.
It's interesting to see the origin of many of these players (trades and drafts), as part of the roster evolution.
I probably have some errors or omissions, but took a shot at this list.
Curious of everyone's thoughts on who makes the team, who gets traded, and where we fill in the gaps with FA acquisitions:
