Nats to honor departing manager Johnson

WASHINGTON -- The Nationals will recognize manager Davey Johnson in a pregame ceremony before Saturday night's game against the Marlins.

The tribute will feature a video montage highlighting Johnson's career accomplishments. General manager Mike Rizzo will also present an award to the 70-year-old manager.

"I heard they're giving me a little something on the [video] screen, that's what I hear," Johnson said. "If it's anything more than five minutes, my back may go out. We've got a ballgame to win."

The reigning National League Manager of Year guided the Nationals to their first postseason appearance last year. During the offseason, he announced that this would be his final season as Washington's manager.

Although the Nationals are still in the hunt for the a Wild Card spot in the National League, this weekend's series is likely Johnson's last home series as manager. But that doesn't mean he is ready to reflect on his time in Washington just yet.

"Probably when we're mathematically eliminated. Then it'll probably hit me," Johnson said. "But until that point, I ain't taking anything for granted. Never have, never will."

Strasburg ready to go after getting skipped

WASHINGTON -- After completing his regular pre-start routine Friday afternoon, Stephen Strasburg did not have any setbacks and is still on track to start Saturday, according to manager Davey Johnson.

Strasburg was scratched from a start on Sept. 13 with tightness in his right forearm. His last scheduled start on Thursday was postponed to Saturday because the tightness returned while the right-hander was playing catch Wednesday afternoon.

Johnson said Strasburg is not more injury-prone than other pitchers. His injuries are simply more scrutinized because of his 2010 Tommy John surgery and status as the team's top starter.

"I think it's who he is," Johnson said. "He's our No. 1 pitcher. Anything that goes on with No. 1 pitchers, high Draft pick, No. 1, there's just a lot of interest. Same thing with [Bryce] Harper. Anything happens to him, everybody analyzes it every which way. It's just part of it."

Strasburg did some light running and played catch on flat ground on Friday without any issue. If the tightness returns before Saturday's game, Johnson said Dan Haren has volunteered to start on short rest.

Worth noting

• When asked about which Nationals might play winter ball this offseason, Johnson listed Zach Walters and Danny Espinosa as two candidates. Johnson said Walters "might" go and whether Espinosa will go is "still in question."

• With Bryce Harper's 20th home run Thursday night, the Nationals became the third team in the Major Leagues to have five players eclipse the 20-homer mark this season -- Ryan Zimmerman (25), Jayson Werth (23), Ian Desmond (20) and Adam LaRoche (20) are the other players and the Blue Jays and Braves are the other teams.
