• Right-hander Dan Haren threw a bullpen session Sunday and didn't have any complaints about his shoulder, which landed him on the disabled list last week. Haren is slated to throw a simulated game on Wednesday or Thursday. Manager Davey Johnson said Haren could avoid a rehab assignment and rejoin the team July 8.
• Left-hander Ross Detwiler told Johnson that he is feeling better and could make his start on Wednesday against the Brewers. The big test will come Monday, when Detwiler will have a bullpen session at Nationals Park. Detwiler complained after back issues after he pitched in Friday's game against the Mets.
