Sandlin struck out one in a perfect inning versus St. Louis on Tuesday.
The right-hander has had some recent uneven performances, allowing six runs (three earned) across 6.1 innings. Sandlin has been a reliable bullpen arm this year with a 2.54 ERA, 1.13 WHIP and 40:17 K:BB, but he's picked up only four holds in 27 appearances. The 24-year-old is unlikely to work his way into a higher-leverage role just yet despite the strong overall performance.
