NEW YORK — Orioles right-handed pitching prospect Trey Gibson is on his way to meet the team in New York, sources said, although if and when the 23-year-old is activated remains to be seen.

Initially, Gibson is on the taxi squad. If Gibson is activated, it will be his major league debut. Baltimore has an opening in the rotation Sunday against the Yankees.

The pitching situation for Baltimore has been thinned due to injuries. Right-hander Zach Eflin is out for the season after undergoing elbow surgery, and right-hander Dean Kremer will miss a few weeks with a quad strain. Left-hander Trevor Rogers is also on the 15-day injured list because of the flu.

Gibson is Baltimore’s top-ranked prospect, according to Baseball America. He carries a 4.01 ERA for Triple-A Norfolk currently.

The Orioles also announced two additional roster moves. They optioned right-hander Tyler Wells and designated Albert Suárez for assignment to make room for lefties Dietrich Enns and Nick Raquet in the bullpen.
