Trey Mancini Wikipedia
Mancini attended Winter Haven High School in Winter Haven, Florida, and the University of Notre Dame. He played college baseball for the Notre Dame Fighting Irish. He played collegiate summer baseball for the Holyoke Blue Sox of the New England Collegiate Baseball League in 2011, and the Harwich Mariners of the Cape Cod Baseball League in 2012.
The Orioles selected Mancini in the eighth round of the 2013 MLB draft. He signed, and made his professional debut with the Aberdeen IronBirds of the Class A-Short Season New York–Penn League. He began the 2014 season with the Delmarva Shorebirds of the Class A South Atlantic League and received a midseason promotion to the Frederick Keys of the Class A-Advanced Carolina League. He began the 2015 season with Frederick, and was promoted during the season to the Bowie Baysox of the Class AA Eastern League. After spending some time in Baltimore during spring training, Mancini returned to Bowie to start the 2016 season. He was blocked at Triple A by Joey Terdoslavich, but was promoted to the Norfolk Tides in April 2016 as Terdoslavich struggled.
Mancini was promoted to the Major Leagues on September 18, 2016. On September 20 in his Major League Debut as the Designated Hitter against the Boston Red Sox, he popped out to right in his first major league at bat. In his second at bat, he hit a home run against Eduardo Rodríguez, making Mancini only the third Orioles' player to hit a home run for their first Major League hit after Larry Haney (1966) and Jonathan Schoop (2013).
Mancini started again two nights later and hit his second career home run, a 3-run homer off David Price. He became the 20th player in Major League history to hit a home run in his first two starts. He would then become only the third player in Major League history to homer in their first three starts, after he hit a solo home run in a 6-1 victory over the Arizona Diamondbacks on September 24.
After a solid spring training, Mancini made the Orioles 2017 Opening Day roster after transitioning to the outfield. He pinch-hit in the tenth inning on Opening Day and collected his first hit of the season.
