De Leon was tagged for five runs (three earned) on four hits over 2.1 innings against the Padres on Wednesday. He walked three and struck out just one, but left with no decision.
De Leon's star-quality numbers in the minors have yet to translate at baseball's highest level, but he remains one of the Dodgers' top prospects. The 24-year-old may not make the playoff roster, but he should be in strong contention for a rotation spot come spring training 2017.
