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

Diaz (finger) remains out of the lineup for Wednesday's game in San Francisco, Matt Kawahara of the Houston Chronicle reports.
ANALYSIS
Diaz is still feeling the effects of a foul tip off his right index finger and will miss a third straight start. He remains day-to-day and could be ready to play Friday versus the Tigers after the Astros' off day Thursday. Victor Caratini will handle the catching duties again Wednesday.

Latest Fantasy Rumors
Seeing less time at DH
CHouston Astros
June 2, 2024
Diaz hasn't made a start at designated hitter since May 17, per Chandler Rome of The Athletic.
ANALYSIS
Diaz made 11 starts at designated hitter in the first seven weeks of the season, but his .636 OPS has prompted the Astros to prioritize other hitters for the position in recent weeks. The 25-year-old hit .282 with 23 homers as a rookie last season while splitting time behind the plate with Martin Maldonado, and Diaz has been unable to maintain that production while operating as Houston's primary catcher. The Astros are intent on Diaz continuing to see opportunities and are encouraged by his defensive progress, but he'll need to improve offensively to regain at-bats at DH and be a reliable fantasy option.
See All MLB Rumors
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.
