Houston Astros fireballer Lance McCullers will make his spring debut on Tuesday which marks an important step in his return from 2016 shoulder trouble that derailed his development. McCullers has all the potential in the world as a major power pitcher capable of racking up an insane amount of strikeouts and his return to action is a good sign that he is feeling healthy. As far as 2017 fantasy baseball is concerned, McCullers was the only guy in Fantasy Sports Boss history who earned a SLEEPER AND BUST label for the upcoming season. He literally can go either way with his season and there is concern his hard-throwing approach won't allow him to hold up physically to starting. That is a debate for another day but for now McCullers can be moved up a bit.
