Stephen Strasburg, who has been nothing but amazing for the Washington Nationals since being called up from the minor leagues, may be sidelined for a little while. Strasburg was warming up in the bullpen prior to last night’s game against the Atlanta Braves, when he just couldn’t get loosened up enough. Washington pitching coach Steve McCatty, approached him before the game to ask him how he felt. Strasburg responded, “I can’t get loose.”

That was enough to have Nationals General Manager Mike Rizzo pull the plug on his start for precautionary reasons. “Stephen was having trouble getting loose in the bullpen, and so I pulled the plug on it,” Rizzo explained.

Strasburg has pitched great since coming to the Nationals. The 22 year old rookie right hander is 5-2 with a 2.32 ERA in 9 starts for the Nationals. Currently he is listed as day-to-day. He will undergo some testing today and tomorrow to make sure there are no major injuries to his shoulder.
