The 26-year-old is a physical specimen with impressive muscle mass on a 6-foot-2 frame. If he ever joins the launch-angle revolution, watch out. He drove the ball into the ground 59 percent of the time with the big-league club last season and had the lowest Average Launch Angle among 387 hitters with at least 100 at-bats. Diaz hit the ball fairly hard (32.8 percent hard contact rate), but without the other piece of the puzzle, the power numbers were non-existent (.064 ISO). He displayed a good approach at the plate, walking 21 times in 179 plate appearances (11.7 percent), as well as decent contact ability (19.6 percent strikeout rate). Those skills along with Jason Kipnis' struggles staying healthy last year give Diaz plenty of appeal in AL-only formats, but he will need to show that he can hit for some power against big-league pitching before he can be justified as a mixed-league starter.
