Item is a baseball signed by the San Francisco Giants' Kelby Tomlinson

Kelby Aaron Tomlinson (born June 16, 1990) is an American professional baseball utility player for the San Francisco Giants of Major League Baseball (MLB). He played college baseball at Texas Tech and was drafted by the Giants in 2011. He bats and throws right-handed.

Tomlinson was called up to the San Francisco Giants on August 3, 2015, to replace the injured Joe Panik. Tomlinson also made his debut that day, hitting a single and scoring a run in the 12th inning of a game against the Atlanta Braves.[6] He started his first major league game on August 5, driving in three runs in his first two at-bats. Tomlinson became the first Giant to hit safely in his first three at-bats since Fred Lewis in 2006.

On August 27, Tomlinson hit a grand slam off James Russell of the Chicago Cubs for his first major league home run. The next day, he got his first walk-off hit: a single against a drawn-in five-man infield in a 5–4 win against the St. Louis Cardinals. On October 3 at AT&T Park, in a 3-2 win over the Colorado Rockies, Tomlinson hit an inside-the-park home run off Chris Rusin. During his rookie season with the Giants, Tomlinson played in 54 games and batted .303 while driving in 20 runs.
