Scott allowed three runs on four hits and a walk over 2.2 innings in Saturday's 12-3 loss to the Angels.
Scott struck out four batters in his major-league debut, relieving struggling starter Yusei Kikuchi. The reliever is expected to be used in long-relief situations. He posted a 3-2 record with a 5.88 ERA over 33.2 innings with Triple-A Tacoma before he was called up by the Mariners on Friday.
