Blake Treinen Autographs
Blake Treinen was born on June 30th, 1988 in Wichita, Kansas. His passion for baseball started at a young age, and by high school, he was already recognized as one of the top pitchers in the state. Treinen attended Baker University in Baldwin City, Kansas, where he quickly became a standout player for the Baker Wildcats.
In 2011, Treinen was selected in the 7th round of the MLB draft by the Oakland Athletics. The right-hander spent the next few years honing his skills in the minor leagues, eventually making his debut for the A's in 2014. Treinen quickly established himself as a reliable reliever for Oakland, and in 2018, he had a breakout season, posting a 0.78 ERA and earning his first All-Star nod. Treinen was traded to the Los Angeles Dodgers in 2019 and continued to perform at a high level, helping the team reach the 2019 World Series.
Throughout his career, Treinen has been known for his fastball-slider combination, which produces a devastating sinker that often induces ground balls. His ability to generate weak contact and his consistent control make him one of the most respected relief pitchers in the game. With several years left in his career, Treinen looks poised to continue his success at the highest level of professional baseball.
