This is what Baseball America wrote when Soler (a Cuban defector) signed:
In a January subscribers-only column, Baseball America described Soler as a kid that,“stands out for his thick, physical build and strength. Power is Soler's best tool, as he shows great bat speed, the ability to hit balls out to all fields and the potential to hit 25 home runs per year. While scouts like his power and some like his swing, he bars his front arm and the stiffness in his stroke is a concern for some scouts. Scouts have offered differing opinions on his ability to hit breaking balls, but he has a history of laying off pitches outside the strike zone in international competition and has more on-base potential than Cespedes. Soler is athletic for his size and there are reports of him running the 60-yard dash in 6.5 seconds—a time that grades out as well above-average speed—but several scouts have said he's really an average runner at best, running better underway than down the line.”
