2025 Fantasy Outlook
Diaz took over as Houston's primary backstop in 2024 and hit 16 homers with a .299/.325/.441 slash line in 148 games, with 99 of those starts coming behind the plate. He was unable to recreate the 23 home runs and .846 OPS he posted in 2023, but the regression isn't a major surprise since he's now handling the most demanding defensive position after previously working as the secondary option. He was also much more productive in the second half of 2024 as he got more comfortable with the added defensive responsibilities. It wouldn't be surprising if Diaz cracks the 20-homer plateau in 2025, and there's plenty of potential for counting stats given Houston's strong lineup. He should again be a reliable fantasy catcher with enough upside to be one of the better producers at the position. Read Past Outlooks
Signed a one-year contract with the Astros in March of 2025.
Homers, plates three in win
Diaz went 2-for-3 with a home run and three RBI in Wednesday's 4-1 win over Boston.

The backstop now has four multi-hit games in August, and he's been a steady bat in the middle of Houston's order throughout 2025. Since the beginning of July, Diaz is batting a strong .281 with seven homers, seven doubles and 19 RBI covering 128 at-bats (34 games).

Stat Review
How does Yainer Diaz compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity and Barrels/PA % are benchmarked against 2019 data (min 400 PA) and Hard Hit Rate is benchmarked against last season's data (min 400 PA). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2024
2023
Despite serving as the No. 2 option in Houston behind Martin Maldonado, Diaz cracked 23 homers and finished as a top-12 fantasy catcher last season. Diaz slashed .282/.308/.538 and Statcast says he actually underperformed in regards to batting average and slugging -- his .287 xBA and .546 xSLG both ranked in the top eight percent of the league. Diaz is not particularly interested in taking walks (2.9 BB%) and his chase rate leaves open some questions about the sustainability of his contact. Further, Diaz's 21.9% HR/FB seems destined to fall, even with the boost provided by the Crawford Boxes. That being said, the Astros have already committed to Diaz being "the main guy" in 2024, and any giveback in the rate stats should in theory be softened by an increase in playing time. He wasn't a big name when he was traded in 2021, but fast forward a few years and Diaz is looking like a key piece on a championship-caliber ballclub.

Latest Fantasy Rumors
Option at first base?
The Astros could consider giving Diaz some playing time at first base, according to Chandler Rome of The Athletic.
Analysis
The 25-year-old has seen most of his playing time behind the plate this season but also has 24 starts at designated hitter. The Astros don't have a clear answer at first base since the release of Jose Abreu, as Jon Singleton likely isn't a long-term solution. Diaz has carried a hot bat since the start of June with an .834 OPS, and seeing some time at first base could help keep him in the lineup while keeping the DH spot open for Yordan Alvarez or other position players. Victor Caratini is closing in on a return from a hip strain, and once he's healthy it could open up a more versatile role for Diaz.
