I'm actually kind of intrigued by Ryan Noda. Obviously you love the walks and base running but he is already use to playing 3 positions and well. And there is some raw power to come that hasn't been displayed in games yet.
Another guy that I'm keeping my eye on that never get mentioned because hes a reliever is Zach Jackson. Only 23 in Double-A striking out guys at a higher rate as he climbs the system. Some command issues at times but hes throwing mid 90's fastballs touching 97. He's only allowed 2 homeruns in pro ball career. Both at Lansing no homeruns allowed at High A, and AA so far.
From a bio last year:
Jackson's best pitch is a hammer three-quarters breaking ball with curveball break and slider velocity in the low 90s. He usually operates at 93-95 mph with his fastball and can hit 97, though it can get straight at times. Jackson doesn't need a changeup much as a reliever, but he has shown some aptitude for throwing one.
