|The Astros' loaded farm system can be a blessing and a curse. On the one hand, it's an exciting acknowledgment of strong scouting and player development work. On the flip side, having a great system sounds great on paper, but if it doesn't funnel players through the pipeline to turn things around at the highest level, it's a bit hollow.

|It's typically seen as a farm-system triumph when an organization's top two prospects graduate to the big leagues and make positive contributions.

Such was the case for the Marlins' pipeline in 2013.

|There's a lot to like about Nathan Karns' arm strength and pure stuff. After he got past labrum surgery, he's been very good and he made it to the big leagues last year with the Nationals. Karns has been a starter throughout his career, but because of his delivery, his command issues at times and power stuff, many have looked at him as a future reliever. The Rays' plan for now, though, is to keep him as a starter.
