When he makes his Major League Baseball debut on Friday night, right-hander Didier Fuentes will reach milestones not seen in years. The Braves prospect, called up from Triple-A Gwinnett to start against the home Miami Marlins, had a birthday on Tuesday. At 20 years and three days, he will be the youngest starting pitcher in the majors since Julio Urias made his debut start for the Los Angeles Dodgers on May 27, 2016.
