2019 Fantasy Outlook
The knock on Diaz coming into 2018 was the total absence of in-game power. He did little to quash that narrative, totaling a mere four homers in 546 plate appearances between Triple-A and the majors, but at least he started to make some adjustments. Diaz shaved nearly six percentage points from his groundball rate at the big-league level (from 59% to 53.5%) while adding more than four percentage points to his flyball rate. His average launch angle was still among the lowest in baseball, but 4.4 degrees is a big improvement over 0, and with that, he was able to tap into some gap power. Over-the-fence power may never come even with further refinement, but Diaz has strong plate skills (15.8 K%, 9.2 BB% last season) and with regular playing time, he could be a nice source of batting average. The question is whether that playing time will come. Following an offseason trade to the Rays, it seems likely. Read Past Outlooks

Past Fantasy Outlooks
2018
2017
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.
A cannon-armed third baseman signed out of Cuba in 2013, Diaz has raked his way through each level of the Indians' minor league system over the past three seasons. After posting a 144 wRC+ and walking more than he struck out (1.50 BB/K) at Double-A Akron, Diaz was promoted to Triple-A Columbus during the 2016 season. Though his walk rate slipped a bit, his bat stayed hot. In 416 plate appearances, the 25-year-old slashed .325/.399/.461 and posted a robust 11.3 walk rate to go along with his 16.8 percent strikeout rate. Having shown that he's a threat at the plate, Diaz has also been identified as one of the top defensive third basemen in the minor leagues. It shouldn't be too long before he makes his MLB debut with the Indians and he is a player worth keeping an eye in deeper leagues and dynasty formats.
