Watch Stephen Drew's inside-the-park home run in the Nationals' 5-1 win over the Phillies

It was already 4-1 Nationals in the ninth inning of Washington's second game of the week with the Philadelphia Phillies in Citizens Bank Park when Stephen Drew stepped in against Philly reliever Colton Murray.

Danny Espinosa's two-run blast in the previous at bat gave the Nats some breathing room in what was a one-run game after eight, then Drew hit a hanger of a 1-1 curve out to right-center where Odubel Herrera tracked it to the out-of-town scoreboard.

Herrera made a valiant, leaping effort, but came up empty and the ball bounced off the scoreboard and over right fielder Tyler Goeddel, who recovered it and threw over the cut-off man and up the third base line, allowing Drew to score for an inside-the-park home run, or what was really a triple with a throwing error probably.

But as of now it hasn't been changed.

"Those were some big insurance runs that we got," Dusty Baker told reporters after the 5-1 win.

"That's the second inside-the-parker that I've seen, I guess, this month," he said, referring to the inside-the-park-er Ryan Zimmerman hit against the Miami Marlins during the last homestand.

So what was Baker thinking as he saw Drew run tonight, and saw third base coach Bobby Henley wave him around?

"I was watching Bobby Henley," Baker said, "and then I was watching Stephen and I was like, 'Oh no!' and then I was like, 'Oh, yeah!'

"When they missed the cutoff man that was big and then when I could see that they missed him and I knew indeed it was an inside the park-er."
