Nationals put Victor Robles on IL one day after dugout tiff

The Nationals placed center fielder Victor Robles on the 10-day injured list with back spasms for the second time this season Wednesday, a day after Washington starter MacKenzie Gore questioned Robles’ effort on a fly ball that fell for a single.

Washington selected the contract of outfielder Derek Hill from Triple-A Rochester to replace Robles on the roster. Robles was sidelined by back spasms from early May until this past Friday. He had started five straight games since his return.

Manager Dave Martinez said Robles told him after Tuesday night’s loss to St. Louis that his lower back was bothering him while running. Robles also got a poor jump on a deep fly ball on Monday that glanced off his glove for a triple. Robles skidded into the center-field wall after failing to make the grab.

“The more I watched him, the more I watched his jumps and stuff, something didn’t look that right, but he kept telling me he was fine,” Martinez said. “After last night I wanted to really sit down with him and talk to him and get out of him exactly what I thought he’d say.”
