Matt Williams on managing his first Nationals camp

NEW YORK -- As he prepared to manage his first regular-season game on Monday, skipper Matt Williams acknowledged that he was both excited and nervous.

He didn't sleep well on Sunday night, but he expected that to happen.

"That's OK. That's part of the deal," Williams said. "We are ready to go. Everybody is ready and so am I. If you can't get excited about Opening Day, something is wrong -- just typical stuff."

When the games start, he hopes to step into the dugout and "get out of [the players'] way and let them go."

"I've never been in this spot before," he added. "Any time you have something that is new, there is a little anxiety to it. The Opening Day thing, I have experience in that regard [as a player and coach]. That's a fine. But I've never been in this spot, so that's anxiety."

Williams makes use of video replay

WSH@NYM: Nationals challenge call in top 10th

NEW YORK -- In the 10th inning of Monday's eventual 9-7 win, manager Matt Williams decided to take advantage of video replay.

With two outs and Washington leading, 9-5, Danny Espinosa hit a ground ball to third baseman David Wright, who threw out Espinosa on a close play to end the inning. As the Mets were coming off the field, Williams went to first-base umpire Clint Fagan and challenged the call.

The crew checked the video, and the call stood.

"It was the last inning, and it was a questionable call," Williams said. "We haven't used [our challenge]. I tried to get out of the dugout as quickly as possible. That's hard, because everyone runs off the field. In that situation, if we could get a guy at first base with two outs, then we want to try and do that. ... It makes you feel a little funny, because you don't want to rub it in. We had to do it for our club in case we get to an opportunity to get a guy at the plate."
