Dominguez is currently considering the rest-and-rehabilitation route, Lauber adds. He intends to pursue additional testing if and when spring training resumes.
In 2018, Dominguez authored a 2.95 ERA and 2.85 FIP over 53 appearances while collecting 16 saves. However, the 25-year-old was held to 24 2/3 innings last year while spending time on the injured list with a sprained ulnar collateral ligament.
Dominguez made two appearances this past spring, throwing two perfect innings while striking out a pair.
