WASHINGTON -- Bryce Harper and Adam LaRoche each drove in two runs, leading the Washington Nationals over the Pittsburgh Pirates 5-4 Friday night for their fourth straight win. Denard Span added three hits as the NL-East leading Nationals opened a 10-game homestand. Tanner Roark (12-7) gave up three runs on five hits over 5 2-3 innings. He struck out four and walked two. Rafael Soriano allowed three hits in the ninth, including Pedro Alvarezs RBI single, but held on for his 29th save. Starling Marte hit a two-run homer and singled for the Pirates, who have lost three straight. Charlie Morton (5-12) lasted just three innings in his shortest start of the season, allowing five runs on seven hits and three walks. The first five Nationals hitters of the game reached base. Morton caught a break when Span was thrown out trying to steal third, but LaRoches single made it 1-0. With bases loaded, Harper fouled a 2-2 pitch off his right foot and needed a several moments to recover. He stepped in and eventually lined a 3-2 pitch to right-centre field for a two-run single, making it 3-0. Harper finished with two hits. Off to a slower-than-usual start this year, he homered twice this week during a three-game sweep of the Mets in New York. LaRoche and Wilson Ramos singled home runs in the third to make it 5-0. The Pirates got to Roark in the fourth. Neil Walker doubled and Marte connected for his sixth homer. Alvarez then doubled home a run with two outs to pull Pittsburgh within 5-3.

Through eight starts in 2014, Harang is proving hes still on top of his game. Two days after his 36th birthday, Harang pitched six strong innings and, backed by home runs from Evan Gattis and Jason Heyward, led the Atlanta Braves to a 5-2 win and a three-game sweep of the Chicago Cubs on Sunday. Harang (4-3) gave up two runs on six hits and two walks. He had nine strikeouts. He is one win shy of matching his total in 26 starts combined with Seattle and the Mets last year, and hes savoring his career revival. "It means a lot, just to get back out here and prove that I can still do this," Harang said. "I know there were probably a lot of people questioning that after last year. Ive been pitching well and guys are playing well behind me and were battling through games. Its been a lot of fun. Ive just got to keep it going." Harang, who was 5-12 with a career-worst 5.40 ERA last year, has a 2.98 ERA this season. The right-hander has allowed more than two earned runs in only one of his eight starts -- nine runs in a 9-3 loss at Miami on April 30. Ryan Kalish, Chris Coghlan and Welington Castillo each struck out twice against Harang. Overall, the Cubs finished with 14 strikeouts. "They have a young, aggressive team over there and I think I was able to take a little advantage of that, knowing how aggressive they are," Harang said. Gattis gave Atlanta a 3-2 lead with his homer off Edwin Jackson in the fourth inning. Heyward added to the lead with his first home run since April 9, a two-run drive off James Russell in the seventh that landed in the Braves bullpen beyond the right-field wall. "It felt like it was longer than that," Heyward said of his power drought. "I keep on showing up every day and trying to put up good at-bats and find goood pitches to hit.dddddddddddd. If you try and do too much, thats when you start to compound things." Jackson (2-3) allowed three runs on six hits and two walks in six innings. "The two balls I got hurt on were balls up and over the middle," he said. "Balls that should be hit. Ive just got to do a better job of getting ahead in the count and working down." David Carpenter pitched the ninth for his second save. B.J. Upton made a sliding catch of Kalishs short fly in centre field to end it. Atlanta closer Craig Kimbrel was rested after pitching two straight days. The NL East-leading Braves have recovered from seven straight losses by winning four of five. The Cubs, last in the NL Central, have dropped seven of eight. Ryan Doumit had a run-scoring single and Andrelton Simmons drove in a run with a double to give Atlanta a 2-0 lead in the second. The Cubs tied it in the fourth on Nate Schierholtzs two-run double. The Braves quickly reclaimed the lead when Gattis hit his eighth homer over the 380-foot sign in left field. Dan Uggla was hit by a pitch from Russell as a pinch-hitter to lead off the seventh. Uggla scored on Heywards third homer.
