Kopech picked up the save over the Padres on Wednesday, allowing one walk over a scoreless ninth inning while striking out one.
Kopech relieved Blake Treinen to open the ninth and retired the first two batters on five pitches before surrendering a walk to Jake Cronenworth. The right-hander was then able to strike out Donovan Solano for the final out to lock down his 15th save of the campaign and his third in the month of September. Kopech has now allowed at least one baserunner in five-consecutive appearances and at least one free pass in four of his last five. However, he's also converted each of his last seven save opportunities, with his last blown save coming back on July 7 against the Marlins.
