The Angels made several relief-pitching moves Tuesday, including calling up highly touted reliever Cam Bedrosian from double-A Arkansas.
Left-hander Wade LeBlanc was claimed off waivers by the New York Yankees. LeBlanc was designated for assignment after throwing 6 1/3 innings in relief of struggling starter Garrett Richards on Friday.
The right-handed Bedrosian had 30 strikeouts, six walks and an earned-run average of 1.47 in 18 1/3 innings at double-A Arkansas.
"Very blessed," Bedrosian, 22, said of joining the majors, adding that his first phone call after getting the news was to his father Steve Bedrosian, a 14-year big league closer and 1987 National League Cy Young Award winner.
The younger Bedrosian said his father and several other family members had arrived in Houston on Tuesday to watch the Angels' three-game series at Minute Maid Park.
Angels Manager Mike Scioscia said of the younger Bedrosian: "His stuff is ready, he's making pitches and we'll see where he fits in our bullpen."
Bedrosian made his major-league debut Tuesday night against the Houston Astros, coming on in relief to start the sixth inning. He retired the Astros in order.
As for Kohn, "first and foremost Michael Kohn needs to find his delivery," Scioscia said. "His last five or six outings, he's struggled with his command, his release point. Be good for him to go down there, work some things out in the minor leagues."
Kohn had walked 10 and allowed six runs in his last seven appearances, including three runs in the Angels' 11-3 loss to the Oakland Athletics on Saturday.
