Orioles outfield prospect Heston Kjerstad, who was the second pick in last year's MLB draft, missed the team's offseason instructional league after what general manager Mike Elias called "an episode of myocarditis" on Friday, according to MASN's Roch Kubatko.
At the time, the team cited a "non-baseball medical issue" as the reason for Kjerstad's absence, per Joe Trezza of MLB.com. Kjrestad is expected to arrive to camp later in spring training.
Myocarditis is an inflammation in of the heart muscle that has been linked to some cases of COVID-19, though there is no indication that Kjerstad has ever tested positive for the virus.
