The Royals announced today that budding star shortstop Adalberto Mondesi has been placed on the 10-day injured list with a left shoulder subluxation. It’s not surprising to hear of the IL placement, but the diagnosis represents a potentially worrying turn to the situation.
The club has not yet given indication as to the course of treatment or anticipated timeline for Mondesi’s return. He’ll be replaced on the active roster by infielder Humberto Arteaga. Just-acquired lefty Mike Montgomery is also coming to the majors, with righty Jake Newberry optioned to make way.
We won’t know more until the team elects to disclose further information, but it is worth noting that shoulder subluxations can be rather significant injuries for position players. In recent years, players such as Marco Hernandez, Guillermo Heredia, and Jesse Winker have required surgery for injuries falling under that category. In Winker’s case, he was declared out for the remainder of the season following a late-July procedure but was able to get back to health for the start of the ensuing campaign.
Regardless of the particular outlook for Mondesi, the club’s unfavorable postseason outlook won’t be altered. But he’s one of the Royals’ chief ballpark draws and it’d certainly be preferable to keep him on the field and gaining further experience against MLB pitching. Mondesi hasn’t quite followed up on his strong output from 2018. Through 335 plate appearances this year, he’s slashing .266/.294/.433 with seven home runs but carries a suboptimal combination of 16 walks and 101 strikeouts.
If Mondesi can find a way to improve in the plate-discipline department and get that OBP heading north, he’d have even greater opportunity to put his exceptional legs to work on the basepaths. As it stands, he already leads the league with 31 swipes. This injury will limit Mondesi’s reps at the plate in 2019, robbing him of some opportunity for further development.
