Oakland filled, Seattle & Pittsburgh are still available.
Seattle - Was 75-87 last year, finishing 4th in the West. They have some good young pieces already on the MLB roster including 25 year old C Chris Ray and 25 year old LF Sonny Lack. They currently have the #10 ranked farm system with 5 players ranked in the Top 100 prospects. They are a team thats on the upswing of their rebuild and have the minor league talent in place that they could move some pieces in an attempt to win now or can continue to add young talent and build for the future.

They currently have the #9th best ranked farm system with 3 players currently ranked inside the top 100 prospects and will be adding to that pool with the #5 pick in this years draft.
