The Los Angeles Dodgers Friday placed left-hander Hyun-Jin Ryu on the 10-day injured list with neck soreness, retroactive to Aug. 1.
The National League Cy Young favorite is having a career year, having gone 11-2 in 21 starts with an MLB-best 1.53 ERA.
However, help is on the way for the Dodgers, as their top pitching prospect Dustin May will make his major league debut against the San Diego Padres on Friday night.
The 21-year-old right-hander is nicknamed "Gingergaard" because his flowing red hair and big-time fastball remind some of New York Mets ace Noah Syndergaard.
May was 6-5 with a 3.38 ERA over 20 starts between Double-A and Triple-A this season. Last month, ESPN's Keith Law ranked him as the No. 13 prospect in all of baseball, and the No. 4 pitcher.
The Dodgers also recalled right-hander Tony Gonsolin from Triple-A Oklahoma City and sent down reliever Dylan Floro on Friday.
The team also shifted left-hander Scott Alexander to the 60-day injured list to make room on the 40-man roster for May.
