Sunday afternoon, Espinosa was 0-for-4. It was his sixth hitless game in the last seven, a stretch that has now featured only one hit in his last 28 at-bats with 13 strikeouts and no walks.

The not-so-subtle implication racing through the Internet of a concussion conspiracy by the Nationals makes as much sense as, well, running into walls. What could they possibly gain by pretending Harper didn't have a concussion or engaging in a game of semantics to avoid using the word?

In the Nationals' brief history, Greinke represents one of their greatest "What if?" questions. What if the right-hander hadn't nixed the rumored trade that would've brought him to D.C. instead of Milwaukee before the 2011 season — and possibly cost the Nationals multiple members of their core?

With Jayson Werth dealing with right hamstring tightness for the last week, Harper has shifted from left to right field twice, and was in the lineup there on Wednesday night.

The Nationals' front office did something similar Wednesday, albeit with a mistake of their own making. To their credit, they reacted properly and rectified the error.

The Nationals' slow offensive start has been concerning to some, worrisome to others and downright nerve-fraying to certain factions of the fanbase. For plenty, it's been maddening to watch them strike out, swinging or looking, so often. To see them come up small in large situations. To hit the ball on the screws, and right at a waiting fielder.

Stephen Strasburg struck out eight in seven innings and the Washington Nationals won a game he started for the first time since Opening Day by beating the Pittsburgh Pirates 5-4 Saturday.

Strasburg played catch Tuesday and went through his usual routine on the day after he pitches, a welcome sight after manager Davey Johnson said Monday night that the right-hander was dealing with forearm tightness.

In a 5-2 loss, the Nationals' bid for a sweep of another National League contender fell victim to singles, some just out of reach, and a hard-throwing rookie left-hander.
