The Baltimore Orioles have promoted touted prospect Kevin Gausman from Triple-A Norfolk before their game against Boston and optioned left-hander Wei-Yin Chen to their Gulf Coast League affiliate.
Manager Buck Showalter said Wednesday ''service time'' allowed the club to send Chen to their Gulf Coast League club in Sarasota, Fla. Chen will be recalled to make his scheduled start Sunday in New York against the Yankees.
Chen is 7-7 with a 3.76 ERA this season. He was the losing pitcher Tuesday against the Red Sox.
Gausman was up earlier this season, going 1-3with a 6.21 ERA in six games, five coming in starts.
