Snead was recalled from Triple-A Las Vegas on Tuesday, Matt Kawahara of the San Francisco Chronicle reports.
Snead made the Opening Day roster but was sent down after posting an 8.74 ERA and 2.38 WHIP in 11.1 innings of relief. His 4.61 ERA across 13.2 frames for Las Vegas isn't particularly impressive, but it does at least come with a strong 20:3 K:BB.
