The Dodgers announced that they’ve placed southpaw Hyun-Jin Ryu on the 10-day injured list with neck soreness. His anticipated timeline to return isn’t yet known.

In other moves, the L.A. org announced the already reported arrival of exciting pitching prospect Dustin May while recalling fellow righty Tony Gonsolin. Reliever Dylan Floro was optioned out to create roster space. Southpaw Scott Alexander moves to the 60-day injured list to make 40-man space for May.

Ryu, 32, has been on an unbelievable run of success since accepting a qualifying offer to remain with the Dodgers. In 21 starts, he has run up 135 2/3 innings of 1.53 ERA pitching while maintaining 7.8 K/9 against 1.1 BB/9 along with a 51.5% groundball rate.

It’s unlikely the veteran lefty will be able to keep up quite that level of output the rest of the way, but he seems to be in top form at an important time for a Dodgers club that just placed a big bet on its existing pitching options at the trade deadline. Given his lengthy injury history and limited accumulation of innings in recent campaigns, it’s not surprising to see Ryu hit the shelf. There’s no indication of the seriousness of the injury, but it’s reasonably likely the Los Angeles organization was as concerned with finding Ryu some down time as it was worried about this particular malady.
