Stras reports no issues after bullpen session

WASHINGTON -- Right-hander Stephen Strasburg showed on Saturday that he is getting better. He threw 30 pitches in a bullpen session and didn't report any problems.

"[Strasburg threw] all of his pitches in the bullpen, [and] came out of it feeling good," manager Matt Williams said. "He is looking at the video, right now."

Strasburg is on the disabled list because of a left trapezius strain. The Nationals are trying to figure out why Strasburg is incurring minor injuries. The team is looking at video of Strasburg's starts to try to figure out the problems.

Before the problems on the left side of his neck, Strasburg had to be pushed back in the rotation in early May because of back problems.

Strasburg's problems started when he hurt his ankle during Spring Training. It's possible he picked up some bad mechanics after suffering the injury. There is nothing wrong with Strasburg's arm, because his fastball is clocked at 98 miles per hour.

Third baseman Yunel Escobar did not start for the second consecutive game because of a sore right wrist. According to Williams, Escobar will get treatment on Saturday and then go in the cage to see how his wrist feels. Williams said Escobar could enter the game as a defensive replacement.
