2024 Fantasy Outlook
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. Read Past Outlooks

Slugs homer in win
CHouston Astros
July 21, 2024
Diaz went 2-for-4 with a solo home run in Saturday's win over the Mariners.
ANALYSIS
Diaz singled in his second at-bat and later added a solo homer in the eighth to extend Houston's lead to two runs. The long ball was Diaz's eighth of the season and his first since June 7 against the Angels. It also marked his sixth multi-hit performance this month, during which he's now batting .306 (19-for-62) with 11 RBI and six runs scored. Additionally, Diaz has hit safely in six of his last seven games.

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.

Latest Fantasy Rumors
Option at first base?
CHouston Astros
July 20, 2024
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.
