WASHINGTON -- Nationals center fielder Victor Robles departed suddenly in the middle of the second inning of Saturday’s 13-9 loss to the Braves with symptoms of dehydration, after he started getting dizzy in the outfield and had trouble standing.

The Nationals announced that Robles had received an IV in the clubhouse after exiting the game, and he was doing much better by the time he walked out of the clubhouse after the game.

“You can't mess with those things like that,” manager Dave Martinez said. “We'll see how he feels tomorrow. He was very light-headed, said his one eye, he lost focus. We got worried a little bit.”

Robles suddenly dropped to one knee in center field during the middle of a Nick Markakis at-bat, but he stood up momentarily while Anibal Sanchez delivered a pitch. Robles quickly fell to his knee once again after the pitch was delivered, causing Martinez and head athletic trainer Paul Lessard to race from the dugout and check on their rookie center fielder.

Robles had not been involved in a play at that point in the game, on defense or at the plate, which made Martinez even more concerned.

“When he went back down, I screamed it out, 'Hold up,'” Martinez said. “He just said he was dizzy. We tried to get him to look up and he said he was real dizzy. When you get to that point, where you're that dehydrated, it's scary.”

Robles eventually walked off the field and back into the clubhouse under his own power, and Michael A. Taylor played the rest of the game in center field.

Robles has been one of the Nationals' hottest hitters at the plate recently, batting .368/.435/.789 with two homers, a triple and seven RBIs in his past six games. Martinez was not sure about Robles' status for Sunday’s series finale.
