LOS ANGELES -- Dodgers pitching phenom Julio Urias was promoted to Triple-A Oklahoma City, and will start for the OKC Dodgers on Monday night against the Iowa Cubs, the team announced.

Urias, who just turned 19 on Aug. 12, put up a 2.77 ERA in 13 start for Double-A Tulsa this season, with 74 strikeouts and just 15 walks in 68⅓ innings.

He missed nearly two months after an elective procedure to correct a condition in his left eye, but since returning to the Drillers he had 28 strikeouts and six walks in 32⅓ innings, including pitching six scoreless innings last Tuesday at Arkansas, his last start in Double-A.

Urias was named the No. 3 prospect in baseball at midseason by Baseball Prospectus, and ranked No. 4 by the trio of Baseball America, MLB.com and Keith Law at ESPN.

At 19 years, 19 days old, Urias is the youngest player in Triple-A.
