Iglesias secured the save Friday against the Mariners after tossing a scoreless inning, allowing one run.
Iglesias has converted each of his last 13 save opportunities and has given up just two runs over his last nine outings since the beginning of September. The 34 saves tied a career-high mark for the seven-year veteran, who is en route to finishing the year with an ERA below the 2.75 mark for the fourth time over his last five seasons.
