The Arizona Diamondbacks added to their stable of talented, young pitching arms in June of 2011 when they selected Trevor Bauer, the Golden Spikes Award winner from UCLA, with the third overall pick of the First Year Player Draft.
Since signing with Arizona, Bauer has dominated at three levels of the minor leagues, going 12-3 with a 3.03 ERA in 23 starts over the last two seasons.
Bauer makes his long-awaited MLB debut Thursday night when he faces the Atlanta Braves at Turner Field.
His debut is the latest in a long line of anticipated appearances in Valley sports history.
