Top-flight Dodgers prospect Dustin May arrives ahead of schedule when he makes his major league debut against the San Diego Padres on Friday night in Los Angeles. The 21-year-old right-hander was expected to reach the big leagues next season but the Dodgers are in major audition mode after being unable to enhance their pitching staff before Wednesday's trade deadline. May, the team's third-round pick in 2016, is rated as the organization's second-best prospect by MLB Pipeline.
