As Trey continued training camp at Fort Huachuca this past weekend, his father was enshrined into the Seattle Mariners Hall of Fame. Griffey surprised his dad with a recorded video segment at Safeco Field.
"I remember growing up, I'd always be in your stuff," Trey said. "I'd take your batting gloves and your bat, run off with it and destroy everything. You were patient with me.
"As I was growing up, I wanted to be just like you. You were my role model. I took another road and went into football, but I can't be more proud of you. You did it. Next time I see you, we're going to celebrate."
The elder Griffey broke into tears after the video played and a near-capacity crowd at Safeco Field roared with applause.
"I just spoke how I felt," Trey said following Monday's practice. "I was upset I couldn't be there to really see him, but I know that it's a great honor for him to be put in the Mariners' Hall of Fame. I was happy for him in every way possible."
Trey is as humble and down-to-earth as any player on the roster, according to receivers coach Tony Dews. His hard work has him in the mix to see some early playing time in 2013.
At 6'3 and 190 pounds, Griffey has the size to make an impact on the outside.
"Trey is an athletic guy and sometimes he shows inexperience, but he really competes," UA head coach Rich Rodriguez said. "He's got a big frame and runs really well, and he makes some unbelievable catches.
"He's just got to be more consistent like any young guy. If he does that, he's going to play a lot."
For a kid with a last name that every sports fan from Tucson to Seattle knows, his unassuming approach to training camp has worked to his benefit.
Just as the case was with his father, the name on the front of the jersey means more to him than the one on the back.
"I go out there and do my best every day," Griffey said. "At the end, the coaches will make their decision and we'll go from there."
