On Tuesday during the Philadelphia Phillies' categorical defeat of the Houston Astros, 7-0, Tim McGraw donned a Phillies jersey circa the ‘70s and ’80s, emblazoned with the name and number of his late father Tug McGraw, a former MLB athlete.

Tug had a major role in securing a ring for the Phillies in 1980, when they defeated the Kansas City Royals in the World Series. The left-handed pitcher played with the organization from 1975 through 1984.

For much of his life, McGraw did not know his father, only discovering he was related to the athlete at age 11.

At the game, McGraw was featured on the jumbotron, and he was elated to show off his father's name.

"I think a lot of people don’t realize I didn’t grow up with Tug," McGraw previously said during an interview on "Today." "I was digging through something and found my birth certificate. It said McGraw. My name was Smith as a kid because my stepdad’s name was Horace Smith."

While they met later that same year, the musician wouldn't see his father again for seven years, when they developed a close relationship.

McGraw said of Tug, "When I found that out, you know, he’s a professional baseball player who’s successful, to me, it made me think that blood is in my veins, so that ability is in there."
