Vladimir Guerrero had many highlights in his Hall of Fame career, but watching his son get his first career hit is something he'll treasure forever.

The elder Guerrero watched Vladimir Guerrero Jr. slap a double down the right-field line in the ninth inning to help set up the Blue Jays' 4-2 walk-off win against the A's on Friday. After Vlad Jr. had gone hitless in his first three at-bats, Vlad Sr. was emotional and giving high-fives in the Rogers Centre suite after his son achieved his first career milestone.

Vlad Jr. will get ready for the second game of his career when the A's and Blue Jays meet today at 3 p.m. ET at Rogers Centre.
