Miller allowed two runs on two walks and struck out one over two-thirds of an inning in Saturday's 6-4 win over the Athletics.
Miller got the nod for a high-leverage spot in relief of starter Trevor McDonald in the seventh inning. He did fine there, but he struggled when staying on to begin the eighth. He walked two batters, and Caleb Kilian allowed both of them to score on a Brent Rooker homer. Miller was activated from the IL on Saturday, as he missed a minimal amount of time due to a back strain and now appears set to compete for late-inning work with Kilian in the near term. Over 13 appearances this season, Miller has a 4.50 ERA, 1.33 WHIP and 18:8 K:BB across 12 innings.
