The 2022 MLB Home Run Derby winner will walk away with more than just bragging rights ... TMZ Sports has learned they'll also get a custom chain and pendant featuring the words "Derby Champ" in 525 Gypsy set Swarovski crystals.
We're told the chain was hand-made in NYC by jewelers Kenny Hwang, Xavier Murillo, and John Luongo ... and MLB will present it to the player who smashes the most homers Monday night.
The chain's 25 inches long (and can be extended to 29 in.) ... and is platinum-plated with 650 handset cubic zirconia.
