Graveman (shoulder) was able to play catch Sunday, Susan Slusser of the San Francisco Chronicle reports.

It's a positive step for Graveman, but he still has plenty of benchmarks to hit in the recovery process before he can be considered close to returning from the disabled list. Jharel Cotton was called up from Triple-A Nashville to join the rotation when Graveman was moved to the DL and has performed adequately as the team's fifth starter, providing a 4.15 ERA and 1.21 WHIP over his last three turns.
