Worth noting

• The Nationals are hoping that outfielder Scott Hairston can be activated from the 15-day disabled list by Sunday against the Phillies. Hairston is 15-for-38 against left-hander Cole Hamels, who is pitching that day. Hairston, who is on a rehab assignment with Triple-A Syracuse, is on the disabled list because of a left oblique strain.

• The Nationals need a pitcher on Tuesday against the Dodgers. Williams said he could use the bullpen with left-hander Ross Detwiler or right-hander Craig Stammen getting the start. It depends on how the relievers are used against the Phillies this weekend. They could call someone from the Minor Leagues to make one start.
