Mederos secured his first career save Monday against San Diego, allowing one hit and one walk in 2.1 scoreless innings. He struck out one.
Closer Raisel Iglesias had worked each of the past two days for Atlanta, so manager Walt Weiss stuck with Mederos to protect a 3-2 lead and gave his usual high-leverage arms the night off. The 25-year-old right-hander has almost exclusively handled low-leverage work in 2026 and shouldn't be expected to see save chances in the future, though he does hold an excellent 0.96 ERA, 0.75 WHIP and 7:2 K:BB over 9.1 innings.
