2020 Fantasy Outlook
Diaz finally unlocked some power with Tampa Bay after homering just once in 299 plate appearances over two seasons in Cleveland. Though his launch angle only moved from 4.4 to 5.7 degrees, that was enough for Diaz to raise his flyball rate more than five points above his career mark, allowing him to easily outdo his prior slugging numbers. Diaz didn't see his plate skills diminish due to the new approach, as he maintained strong strikeout (17.6%) and walk (10.2%) rates and ranked in the 82nd percentile of all players in hard-hit percentage. While he met expectations from a skills standpoint, durability was a concern for Diaz, who spent time on the shelf with hand, hamstring and foot injuries. If healthy, Diaz should open 2020 in a regular role at the hot corner, though the Rays' wealth of options could push him into short-side platoon duty if he falls into a prolonged slump at any point.

Optimism for return growing

Hamstring
September 26, 2020
Diaz (hamstring) went through what manager Kevin Cash labeled a "lighter day" of workouts Saturday, and optimism remains high for his availability early in the postseason, Juan Toribio of MLB.com reports.
ANALYSIS
Diaz ran the bases and hit live pitching Friday, and although he wasn't as active Saturday, he remains on track to suit up sooner rather than later. Cash noted Diaz and fellow injured infielder Ji-Man Choi will have a more comprehensive workout again Monday, at which point there will be more clarity on both players for a postseason that begins Tuesday. Diaz will have some rust to work off when he does return, considering he last saw game action Aug. 31.

Past Fantasy Outlooks
2019
2018
2017
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.
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.
