Montero was tagged with a blown save Saturday against Cleveland after allowing three runs on two hits and two walks across one inning. He didn't record a strikeout.
Montero entered the bottom of the ninth inning holding a three-run lead. After retiring the first two batters he faced, he struggled badly, allowing back-to-back walks and back-to-back hits to erase the three-run advantage in only a matter of minutes. Montero has now allowed runs in two of his last three appearances.
