Andrés Muñoz - Suffers blown save Sunday Munoz (5-6) blew the save and took the loss Sunday against the Athletics. He allowed two runs on two hits and no walks while striking out one over two-thirds of an inning.

Impact With a one-run cushion, Munoz recorded a pair of outs in the eighth inning but was unable to secure the victory in the ninth frame, serving up a walk-off two-run homer to Lawrence Butler. Sunday marked the hard-throwing right-hander's 10th blown save, as he's endured a down 2026 campaign. In 55 innings, Munoz owns a 4.25 ERA, 1.18 WHIP and 86:23 K:BB with 27 saves.

Bryce Miller - Wild in no-decision Miller did not factor into the decision Sunday, allowing two runs on two hits, five walks and a hit-by-pitch over five innings against the Athletics. He struck out five.

Impact After allowing a pair of solo homers in the first inning, Miller was able to work four scoreless frames the rest of the way, though his control was poor. The right-hander has stumbled of late, going 0-4 with a 7.29 ERA, 1.68 WHIP and 32:21 K:BB over his past seven outings spanning 33.1 innings. On the year, Miller owns a 4-9 record with a 4.19 ERA, 1.16 WHIP and 106:34 K:BB across 107.1 innings (20 appearances). His next start is tentatively lined up for next weekend on the road against the Rockies.

Impact Lopez worked two scoreless frames before running into trouble in the third and fourth innings, departing at 102 pitches (63 strikes). While Sunday's showing was subpar, the southpaw has been much better in the second half, posting a 3.34 ERA, 1.20 WHIP and 64:22 K:BB across 59.1 innings (11 starts) since the All-Star break. With an overall 6-4 record, 5.02 ERA, 1.48 WHIP and 107:56 K:BB in 114.2 innings (25 appearances), Lopez is tentatively scheduled to make his next start Saturday against the Guardians.
