Yainer Diaz

24-Year-Old DHDH
2023 Fantasy Outlook
Diaz is a good enough hitter that he should get backup catcher work this season and beyond. It will be his defensive development that determines whether he becomes a workhorse behind the plate. On lesser teams, he might get work at first base and designated hitter in addition to catcher, but those starts should be few and far between when the Astros are fully healthy. The one major flaw in Diaz's offensive game is how frequently (38% in the minors) he chases pitches out of the zone. He hit .306/.356/.542 with a 31.3 Hard% and 25 home runs in 105 games between Double-A and Triple-A. Despite his propensity to chase, Diaz logged a stellar 17.8 K% at Triple-A, but walked just 5.9% of the time. Diaz was age-appropriate for a catcher in the upper levels. Read Past Outlooks

#582
ADP
$Signed a $25,000 contract with the Indians in December of 2016. Traded to the Astros in July of 2021.
Chance to earn role
DHHouston Astros
February 24, 2023
Diaz will have the chance to win the backup catcher job this spring, Paige Leckie of MLB.com reports.
ANALYSIS
Martin Maldonado is penciled in as the starting backstop in Houston, but the depth chart is unresolved from there. Diaz seems big-league ready with the bat -- he maintained a 121 wRC+ across 219 plate appearances with Triple-A Sugar Land in 2022 -- but his defense is more questionable. Upon reporting to camp, Diaz noted that he focused on improving all facets of his defense this offseason in an effort to stick in the majors. He is competing with fellow prospect Korey Lee for the role, though Diaz's bat-first profile may help him given that Maldonado is a strong defensive catcher but offers little at the plate.
