Nationals select RHP Roark from Triple-A Syracuse

The Washington Nationals called up right-handed pitcher Tanner

Roark from Triple-A Syracuse, optioned left-hander Xavier Cedeno

back to the minors and moved lefty starter Ross Detwiler to the

60-day disabled list.

The moves came before Washington’s game against Atlanta on

Tuesday night.

Roark is 9-3 with two saves and a 3.15 ERA in 33 games at

Syracuse in 2012, 11 as a starter. He could work in relief for the

Nationals right now, then start when rookie right-hander Taylor

Jordan’s innings limit is reached, which is expected to happen

after about four more appearances.

The Nationals got Roark in the trade that sent shortstop

Cristian Guzman to the Texas Rangers in 2010.

Detwiler went on the 15-day DL on July 7 with a herniated disc

in his back.
