Scott Olsen has officially been named the Nationals' starting pitcher for tomorrow's series finale against the Braves.
Olsen, who has been on the DL since May 22 with left shoulder inflammation, has made four minor-league rehab starts, the most recent coming Thursday for Class A Potomac. Overall, he posted a 3.21 ERA while on rehab, striking out 11 while walking only one batter.
In eight starts with the Nationals before getting hurt, Olsen was 2-2 with a 3.77 ERA.
Olsen's return tomorrow pushes Craig Stammen back to Friday night's game against the Phillies and Ross Detwiler to Saturday night's game. Sunday's starter remains uncertain; if Stephen Strasburg is ready to return from his shoulder inflammation, he'll pitch on schedule. If not, the Nationals will need to decide whether to promote someone from the minors or use long reliever Miguel Batista again.
