What It Means:

Nelson moved to 4-2 with a 3.05 ERA. He might not be an every-week play in mixed leagues just yet, but he does seem to be getting closer.

Nelson's 4.3 SIERA suggests he's been fortunate. He still needs to bring down the walk rate (10.8 percent) a tad; he's issued 17 free passes in 38 1/3 innings.
