DENVER - Adam LaRoche has been scuffling this month. He hopes one swing will turn things around. LaRoche broke out of a July slump with a tiebreaking home run in the seventh, Anthony Rendon had three hits and the Washington Nationals rallied to beat the Colorado Rockies 7-4 on Tuesday night. It was the Nationals fourth straight win and increased their NL East Division lead to two games over Atlanta, which lost to Miami on Tuesday. The win might have come at a cost after third baseman Ryan Zimmerman left the game in the sixth inning with a strained right hamstring. He is scheduled to have an MRI done Wednesday morning. "Its pretty sore tonight. Get the MRI, get some results tomorrow and see where were at," manager Matt Williams said. "Its concerning. Anytime you have to leave the game with a hamstring injury its concerning." Zimmerman missed 44 games with a fractured right thumb earlier this season but has played well since coming off the disabled list on June 3. "Hes swinging great, playing great, but we have to deal with it," Williams said. "Well see how he feels tomorrow and what the doctors say." Ian Desmond followed Mondays 5-for-5 performance with hits in his first two at-bats Tuesday for Washington. He was hit by a pitch in the sixth to reach base safely in eight consecutive plate appearances. The streak ended when he struck out in the seventh, but the Nationals had taken control on LaRoches three-run homer off reliever Rex Brothers. It was LaRoches first home run off a lefthander since May 28, 2013. "You swing hard enough enough times youre bound to run into somethings. Ive been playing long enough to know a lot of times it takes one swing," LaRoche said. "Ive been in a rut for a little while, my timings been out of whack, so this came at a good time." Nolan Arenado and Corey Dickerson homered for the Rockies, who have lost seven straight and remain tied with Texas for the worst record in the majors. Before the game the Rockies placed shortstop Troy Tulowitzki on the 15-day disabled list with a left hip flexor strain and recalled left-hander Yohan Flande. Tulowitzki is the third Colorado player in two days to hit the disabled list. First baseman Justin Morneau (neck) and reliever Boone Logan (diverticulitis) were put on the DL on Monday, adding to the long list of Rockies out of action. "Its unfortunate, its what Im dealt with, Ive been dealt many, many things in my career," Tulowitzki said. "This is just a bump in the road." Flande started well before faltering in the sixth. He allowed four runs on five hits and walked two in 5 1-3 innings. He left with a 4-2 lead and runners on the corners, but Colorados bullpen couldnt hold it. Zimmerman made it 4-3 with a fielders choice but left the game after hitting the first base bag hard trying to beat out his grounder. "Guys just coming back from the DL, getting his swing back and you hate to see that," LaRoche said. "Cross our fingers its nothing major." Wilson Ramos tied the game with an infield single, and then the Nationals broke it open in the seventh. Brooks Brown (0-1) walked Denard Span and Rendon singled. Brothers relieved Brown one out later and LaRoche pulled a 93-mph fastball into the Rockies bullpen to make it 7-4. It was his 13th of the season and his second hit of the night off a lefty. "When youre facing a bunch of lefties it can get you right again because you have to stay on the baseball," Williams said. Reliever Craig Stammen (1-4) pitched a scoreless inning to get the win. Rafael Soriano worked the ninth for his 23rd save. The Rockies took a 1-0 lead in the second on DJ LeMahieus RBI triple to right. Arenado made it 3-0 in the second with a two-run homer to centre. It was his seventh of the season and first since May 5. The Nationals got two back in the fourth before Dickersons solo shot to the upper deck off Jordan Zimmermann in the fifth made it 4-2. NOTES: LaRoche holds the franchise record for consecutive plate appearances reaching base safely with nine. ... LeMahieu finished with three hits. ...

Durant and his Oklahoma City teammates agree those shots will fall. Saturday night in Game 4 would be a good time to start, or the Thunder could find themselves on the brink of playoff elimination in the opening round for the first time since 2010. "I just didnt make shots," Durant said Friday after practice. "Thats the name of the game. But I liked the way I cut, I liked the way I was aggressive. But I have to do a better job of maybe passing the ball a little bit more and also making shots. Ive got to stay confident in myself." Durant and Westbrook each scored 30 points in Thursday nights 98-95 overtime loss to the Memphis Grizzlies, combining to go 19 of 53 or a majority of the 87 shots the Thunder took. Worse, they were a chilling 4 of 21 beyond the arc with Durant missing all eight of his attempts. Thunder centre Kendrick Perkins said that wont happen again. "KD is obviously the league MVP and we expect him to be the MVP down the stretch," Perkins said. Memphis has been making Durant and Westbrook work hard for shots by crowding the paint while holding the Thunder below 40 per cent shooting in back-to-back games. Now the Grizzlies have the same 2-1 lead they had a year ago in the semifinals against Oklahoma City after consecutive overtime wins. Grizzlies coach Dave Joerger said they want to limit the easy shots and hope Durant and Westbrook miss some. "Theyre going to get them up," Joerger said. Durant and Westbrook werent alone. Oklahoma City went 5 of 28 for a chilling 17.9 peer cent.dddddddddddd That was just the seventh time in the playoffs the Thunder have shot 20 per cent or less from 3 since moving to Oklahoma City, and three came against the Grizzlies. Thunder coach Scott Brooks said the Grizzlies have been forcing them to take some of the 3s by crowding three and four players around the paint. Oklahoma City can loosen up Memphis by hitting some of those "The ones were trying to eliminate and hopefully we do that next game, are the ones that are off the dribble with the no passes. Those are the tough ones. Those are the ones that we dont want. The ones we like, and were going to have to be able to step up and make, are the ones when theyre packing the paint." Still, the Thunder, who posted the NBAs second-best record, remain confident. "Itd be different if we got blown out or we feel like we didnt have a chance to win," Westbrook said. "Were in a good place." So are the Grizzlies. They now have won four of the last six playoff games against Oklahoma City, including four straight on their home court. The Thunders lone win here in the post-season needed three overtimes in Game 4 of their 2011 semifinal. Not even going to overtime after blowing fourth-quarter leads has bothered Memphis, which has been pushing for the playoffs since January once centre Marc Gasol returned from a sprained left knee. The Grizzlies went 10-4 in games decided by three points or less as one of only four teams with double-digit wins in one-possession games. Conley called Saturday night the next most important game of the season. "We know theyre not going to go away," Conley said. "Theyre going to fight and do whatever they can to win the series."
