Munoz pitched a perfect inning and struck out one to earn the save in Sunday's 2-0 win over the Athletics.
Munoz finished the job after Bryan Woo's eight innings of one-hit ball. A rough end to August saw Munoz work in non-save situations for his first two games in September, and he's started the month with 2.2 perfect innings. He's had his share of struggles this year with a 4.13 ERA, 1.15 WHIP and 83:20 K:BB through 52.1 innings this season. He has converted 25 of 34 save chances this year.
