WASHINGTON -- Pirates manager Clint Hurdle said before Thursday's game with the Nationals that pitcher Jeff Karstens was doing well after throwing Wednesday.
"He feels good today," Hurdle said. "We'll go with the bullpen [session] tomorrow in Detroit, and then we'll evaluate that and see how he feels Saturday, and then [put] the next step in place."
Karstens has been on the disabled list since April 18 with shoulder inflammation, and he threw 20 pitches before Wednesday's series opener in Washington.
Karstens is 0-1 with a 4.50 ERA in three starts this season.
