The Angels selected Campero's contract from Double-A Rocket City and placed him on the 10-day injured list Saturday due to a fractured hand.
Campero was hit by a pitch and suffered a fracture on his hand in Rocket City' game against Montgomery on Sunday, so he'll have to wait to make his 2026 big-league debut. Campero slashed .287/.375/.455 with six home runs and 27 RBI in 167 plate appearances at the Double-A level, and he's taking the 40-man roster spot of Omar Martinez, who was designated for assignment Saturday.
