Montero posted the save in a 3-2 win Saturday, getting one strikeout while allowing one run on two hits against the Rangers.
Montero entered the ninth with a two-run lead and allowed one run to score before inducing a Brock Holt fly out with Joey Gallo on third to end the game. Montero leads the M's in saves despite a 5.01 ERA, but Kendall Graveman (COVID-19) was the preferred option in the ninth before he landed on the IL, and relievers like Erik Swanson (groin) and Keynan Middleton have also picked up saves in the last week.
