The San Antonio Spurs today announced that forward Jeff Pendergraph has formally changed his last name to Ayres.

Ayres is the family name of his biological father, James. It replaces the surname of Jeff’s former stepfather.

According to Jeff McDonald of the San Antonio Express News, “I didn’t know who my dad was until I was a senior in high school,” Jeff Ayres said Wednesday, during a break from pickup games at the Spurs’ practice gym. He was born Jeff Orcutt, using his mother LaDona’s maiden name, and became Pendergraph in elementary school when she married. Growing up in Rancho Cucamonga, Calif., 45 miles east of Los Angeles, the future Jeff Ayres dreamed his biological father was someone famous, such as Denzel Washington or Shaquille O’Neal. A doctor. A musician. Somebody who was somebody. “It turns out it was a mechanic named James,” Ayres said.”
