Nationals' Trevor Williams: Lands on IL with flexor strain

The Nationals placed Williams on the 15-day injured list Tuesday with a right flexor strain, Bobby Blanco of MASNSports.com reports.

Williams had been slated to start Tuesday's game against the Mets but now will be sidelined for at least two weeks, and quite likely longer. The veteran right-hander has been a pleasant surprise for the Nationals this season, collecting a 2.22 ERA in 11 starts. DJ Herz was called up from Triple-A Rochester and will start Tuesday in Williams' stead.
