Last Saturday, Kaiser Carlile -- a nine-year old bat boy for the Liberal Bee Jays -- was hit in the head by a batter taking a practice swing in the on-deck circle.
On Monday, the Giants purchased the contract of Kelby Tomlinson and added him to the active roster.
Later that night, he delivered a pinch-hit single in his first career big-league at-bat.
Following the game, Tomlinson paid tribute to Carlile in a video posted to Facebook by Tyler Prater of Liberal, Kansas.
"This is Kelby Tomlinson here. Man has it been a crazy couple of days but in the mix of all of our excitement, we remember Kaiser and the entire Carlile family.
