The Houston Astros will most likely look to the free agent or trade market to fill some of these needs. The other needs, they might fill from in-house options. The team now has George Springer and a bunch of young guys set to fight for the other two outfield spots.
I wouldn’t rule out Teoscar Hernandez from earning a full-time role in 2017. He showed some potential in his cup of coffee in 2016. Then you have Jake Marisnick and Tony Kemp, but I see them more as 4th or 5th outfielders.
