The Philadelphia Phillies are in a bit of a pickle when it comes to determining who will be their starting catcher next season.
J.T. Realmuto is a free agent, and while most seem to believe he will be back in Philadelphia for 2026, there are absolutely no guarantees on that front.

The Phillies may have to seek alternatives, and with the catcher market being thin (as always), they would have to get creative if Realmuto does depart.
On that note, Theo DeRosa of MLB.com has identified a very intriguing trade target for Philadelphia: Houston Astros backstop Yainer Diaz.
“One trade candidate mentioned by MLB.com’s Mark Feinsand who could make sense for the Phillies is Astros catcher Yainer Diaz, who hit 20 home runs in 2025 and has significant offensive potential despite poor defense behind the plate,” DeRosa wrote.
Diaz entered the big leagues with Houston in 2022, but did not begin to earn significant playing time until 2023. That season, he slashed .282/.308/.538 with 23 homers and 60 RBI over 377 plate appearances.

The 27-year-old then became the Astros’ full-time starting catcher the following year, slashing .299/.325/.441 with 16 long balls and 84 RBI across 619 trips to the dish.

Last season, Diaz slashed .256/.284/.417 in what was actually a significant step back for the Dominican native, but his .277 BABIP indicates that he may have been the victim of some bad luck.
And as DeRosa noted, Diaz isn’t the greatest defensive backstop in the world. While he has a terrific arm, he struggles mightily in terms of pitch framing, an area in which Realmuto has always excelled.
Diaz is under team control through 2028, so Houston does not have to be in any rush to move him. The cost to acquire him would surely be extravagant, and with the Phillies having a thin farm system as it is, they may not be willing to pay that cost.
This will all ultimately come down to just how much money Realmuto wants to secure in his next deal. There had been speculation that he could land a three-year, $45 million contract, which seems a bit much for a declining 34-year-old who registered a .700 OPS this past season.
If Realmuto ends up bolting, Philadelphia could be in some trouble behind the plate.
