who is in the 2026 home run derby

The only confirmed participant I found for the 2026 Home Run Derby is Junior Caminero of the Rays, who is reported as the first player officially in the field. The event is set for July 13 at Citizens Bank Park in Philadelphia.

What’s confirmed

• Junior Caminero, Tampa Bay Rays.

• The Derby is scheduled for Monday, July 13, 2026, at Citizens Bank Park.

What’s still pending

The rest of the eight-player field has not been fully announced in the sources I found, so any other names would still be speculative. MLB’s official participant page says the story will be updated as more sluggers join the competition.

Context

A few reports also mention Bryce Harper as a possible participant, but those are framed as status updates rather than a finalized confirmation, so I would treat that as unconfirmed for now. TL;DR: So far, the only name officially in the 2026 Home Run Derby is Junior Caminero.
