TUCSON (KGUN9-TV) - Trey and Taryn Griffey are Wildcat athletes, college roommates, brother and sister.
Growing up, "we'd play full-blown, like I was one of his friends," Taryn admits.
"I would always throw a baseball or football at her, force her to catch it, somewhat tortured her but made her better in a way," older brother Trey laughs.
"He (Trey) never wanted to lose so I feel like that gave us a competitive edge."
But many would argue that the competitive edge is woven into their DNA.
Trey, 21 years old, and Taryn, 20, call baseball icon and future Hall of Famer Ken Griffey Jr. "dad."
"I mean growing up dad was just dad," Taryn says.
The siblings who grew up between Seattle and Orlando played baseball and softball, but found love in other sports they now play wearing Arizona red and blue.
"I stopped playing baseball because I didn't have the love for it as far as I did for football," Trey says. The wide receiver is credited with one of the U of A's biggest plays of the 2015 season, a 94 yard touchdown against Arizona State.
After missing almost three years with an ACL injury, Taryn is now Arizona women's basketball's second leading scorer so far this season.
"It's been a while since I've heard my name called, I'm just happy when I hear it called. I'm always smiling out on the court," Taryn says.
