12:37pm: The diagnosis is brutal for the Dodgers, as Roberts revealed to reporters that Ryu won’t return before the All-Star break (Twitter links via Pedro Moura of The Athletic). The injury sounds rather gruesome. Roberts explained that a muscle in Ryu’s groin tore completely off the bone.
Ryu will be replaced in the rotation by top prospect Walker Buehler (Twitter link via Andy McCullough of the L.A. Times). J.P. Hoornstra of the Southern California News Group adds that Buehler is on an innings limit, however, so he although he will nominally be the team’s fifth starter, he may not technically start every fifth day.
12:12pm: The Dodgers announced that they’ve placed left-hander Hyun-Jin Ryu on the 10-day disabled list with a left groin strain and optioned infielder Breyvic Valera to Triple-A on Thursday. In a pair of corresponding moves, utilityman Tim Locastro and right-hander Yimi Garcia have been recalled from Triple-A.
The press release didn’t include any sort of timetable for Ryu’s return, though manager Dave Roberts said after last night’s game that the strain was a “pretty good” one and called the injury a “big loss” for the team, which doesn’t exactly exude optimism regarding a minimal DL stay for Ryu. Roberts is hardly exaggerating when he calls any absence for Ryu significant, as the 31-year-old has dominated opposing lineups in 2018, working to a 2.12 ERA with 10.9 K/9, 3.0 BB/9, 0.9 HR/9 and 56.7 percent ground-ball rate in 29 2/3 innings.
Garcia, 27, will give the Dodgers the potential for a quality boost to the relief corps in what will be his first MLB action since undergoing Tommy John surgery back in 2016. Garcia possesses a 3.12 ERA with 9.7 K/9, 1.4 BB/9, 1.2 HR/9 and a 30.6 percent grounder rate in 75 innings at the Major League level and looked to be an emerging key cog in the L.A. bullpen before incurring his torn ligament. So far in Triple-A, he’s allowed three runs in 7 2/3 innings of work and picked up seven strikeouts without issuing a walk.
Locastro, 25, has experience at both middle-infield slots and in the outfield corners. He has just one MLB plate appearance under his belt but was off to a fast start in Triple-A, hitting .342/.448/.507 there. Valera, 26, has similarly impressive Triple-A numbers this season and was hitless in four MLB plate appearances. Locastro, though, has more recent experience at shortstop, so it seems he’s viewed as the better option to help provide depth in Corey Seager’s absence for the time being.
