What It Means:

Rondon has been on the disabled list since August 19, and this was his first time throwing since then. He still has a lot of rehab work ahead of him, and plans to go through another flat-ground throwing session before working from a mound.

Rondon is having a terrific season, with a 2.47 ERA and career-bests in SIERA (2.37), strikeout rate (31.1 percent) and walk rate (3.7 percent) across 43 2/3 innings pitched.
