5. OF Domingo Santana– Santana was acquired as part of the Hunter Pence deal and got his first taste of big league action in 2014. That taste was pretty sour though, as Santana struck out in 14 of his 18 plate appearances. The thing that makes me put Santana so high is the power he has. It’s amazing, and if he can get control of the strikeouts, I think he could become a .260-.270 hitter that chips in 30 homers from the seven spot of the order for Houston. Grade: B Upside: Big power.
