The Los Angeles Dodgers selected Eovaldi in the 11th round of the 2008 MLB Draft . His draft stock had fallen because of his first Tommy John surgery. Eovaldi signed with the Dodgers, receiving a $250,000 signing bonus , forgoing his commitment to Texas A&M.

In the game, he picked up the win, while pitching five innings, allowing only two runs while striking out seven. He also hit a single in his first major league at bat and scored a run. His seven strikeouts were tied for fourth in Dodgers' history for a major league debut and he was only the fourth Dodger pitcher to score a run in his debut since 1960.  Eovaldi became the first Dodger starter since Danny McDevitt in the 1957 season to start his career with four games of five innings or more while allowing two runs or less.
