Worth noting

• Following Saturday's doubleheader, the Nats will have played 81 games, the exact halfway point of the season.

"For me, certainly not where we'd like to be and also not where we could be given all that's gone on," Williams said. "I think we've got a group of guys that continue to battle hard every day, that use nothing as an excuse and play."

• Entering Saturday, Washington had committed just three errors since June 7. They've posted a .992 fielding percentage this month after struggling to a .975 percentage in April and a .980 percentage in May.

• The Nationals were 19-14 and averaged 4.6 runs per game when Zimmerman was in the starting lineup. Entering Saturday, they've gone 22-24 while averaging 3.5 runs per game without him. Zimmerman started in left field in Game 1 of Saturday's twin bill.
