WASHINGTON — Daniel Murphy turned to one of his most reliable strengths to win a game for the Washington Nationals.

Murphy delivered on a day when his bobbleheads were given out to fans, hitting an opposite-field double to score Bryce Harper in the 10th inning and send Washington over the Philadelphia Phillies, 3-2, on Friday.

“You don’t take him for granted,” manager Dusty Baker said. “You realize this guy is one of the best hitters in the world.”

“That hit to left really doesn’t surprise me because that is his bread and butter. This is how he made his living prior to him hitting the ball out of the ballpark in the [2015] playoffs until today. When a guy goes to the opposite field with authority, that’s hard to teach,” he said.

Shawn Kelley (1-0) pitched a perfect 10th inning. The Nationals’ bullpen allowed only two base runners and no runs in three inning.

The Phillies lost their fourth in a row. They took two of three from the Nationals in Philadelphia last weekend.

Washington has won three of four.

“It was a good way to start the weekend,” Murphy said.

Harper opened the 10th with a single off Jeanmar Gomez (1-1), then made it home on Murphy’s double into the left-field corner.

“I was trying to score,” Harper said. “You don’t want to play extras. It’s tough trying to go out there. Those extra innings, you don’t want to do that to your bullpen.”

Gomez (1-1), who was removed from the closer’s role this week after earning 37 saves last season, threw a scoreless ninth before Washington broke through. Gomez has allowed seven runs in 51/3 innings this month.

“We go 10 or 12 innings, now are we going to run out of pitching,” Phillies manager Pete Mackanin said. “That’s his job now to give us multiple innings.”

Murphy extended his hitting streak to 10 games.
