Julio Urias will appear in his first major league game on Friday, and he will do so more than two months before his 20th birthday. This is a rare thing, so much so that the last Dodgers teenage pitcher was Fernando Valenzuela in relief in September 1980.
The last MLB starter under 20 years old was Felix Hernandez, who made 12 starts at age 19 in 2005.
Then again, Urias has been a rarity since dominating the Midwest League at age 16.
The last Dodgers starting pitcher before his 20th birthday was Dick Calmus on Aug.
