WASHINGTON -- Rookie Luis Perdomos big league debut must seem like a long time ago.Perdomo pitched seven solid innings, Matt Kemp homered twice and drove in four runs and the San Diego Padres beat the Washington Nationals 5-3 on Friday night.The Padres have watched the 23-year-old right hander steadily evolve after allowing six runs in one relief inning in his first major league game.I always go back to that first outing he had, Opening Day against the Dodgers, and he just looked shell-shocked on the mound, manager Andy Green said. And now this guy knows that he can navigate through the Washington Nationals lineup at this point in the season.Perdomo (4-4) is 3-0 with a 3.47 ERA in his last four starts. After allowing a pair of first-inning runs, he limited the National to two hits over the final six innings of his longest outing. He got 13 outs via ground balls.I really just followed my plan, Perdomo said through an interpreter. I kept my pitches low and I was able to use my sinker to get some outs.Brandon Maurer pitched 1 1/3 innings for his fourth save.Kemp hit a solo shot in the first inning and gave San Diego the lead for good with a three-run homer in the fifth. He has six homers in his last six games and the Padres have homered in 20 straight, the longest streak in the National League this season.Jayson Werth and Daniel Murphy homered for Washington. The Nationals have lost four of five.People ask me what do we need? We need some timely two-out base hits. Not home runs, manager Dusty Baker said. We rely on home runs, which is fine. But you need some timely two-out hits or two or three consecutive hits, which we arent getting.Tanner Roark (9-6) turned in his shortest outing since June 5, lasting just five innings. He allowed five runs on four hits and surrendered two homers in a game for the first time this season.I didnt have my best stuff by any means tonight, Roark said. I stunk.Both teams were warned after Washingtons Oliver Perez hit Brett Wallace with a pitch to open the ninth.Washington pitchers hit three batters and San Diego hurlers hit one.Wilson Ramos had three hits for Washington.San Diego trailed 2-1 when Wallace was hit leading off the fifth and scored on a two-out single by Melvin Upton Jr. After Ryan Schimpf walked, Kemp homered to center off a 2-1 Roark fastball for his 22nd of the season.Murphys solo shot pulled Washington to 5-3 in the eighth.Kemp made it 1-0 when he deposited Roarks 3-1 pitch into the Padres bullpen.He left a couple of (fastballs) up there in the zone, Kemp said.Werth tied it in the bottom of the first with a line shot to center. He has reached base in 26 consecutive games.Bryce Harper then walked, stole second and scored on Ramos single.TRAINERS ROOMNationals: RHP Joe Ross (right shoulder inflammation) will make a rehab start Sunday at Class-A Hagerstown. ...

A knee to the thigh might have stung him the most, but his sixth straight double-double made up for the brief burst of pain. Melbourne coach Paul Roos has cautioned success-starved fans against expecting too much too soon from his young AFL side.The Demons sit ninth on the ladder and remain a highly-unlikely chance of sneaking into the top eight this year.They could return to finals for the first time since 2006 if they defeat Carlton and Geelong, while eight-placed North Melbourne would need to lose to Sydney and Greater Western Sydney.The Demons, who have won three on the trot including an upset over flag favourites Hawthorn, would also need to bridge a percentage gap of 3.7.Roos noted on Wednesday that his charges were rightly excited about playing meaningful football so close to September.But the 53-year-old, who will hand the reins over to Simon Goodwin at seasons end, was circumspect regarding the Demons prospects in 2017.Theres going to be a period of success. Exactly when we play finals, I cant give that assurance, Roos said.I think they (fans) still understand were a really young team. We even have to remind ourselves of that as well.All but about twice this year, against our opposition weve been younger. On about 12 or 13 occasions weve been the youngest team in the competition on that weekend.Were hoping there is an enormous amount of improvement (left) and there is. But were just not sure (when it will happen) .dddddddddddd. its a great list so its pretty exciting.Gun ruckman Max Gawn and influential midfielders Jack Viney and Dom Tyson have all played less than 70 matches.Young forward Jesse Hogan and other recent draftees are yet to hit the 50-game mark.Roos suggested every player at the club will learn plenty from the final two rounds of the season but they must only worry about defeating Carlton at the MCG on Sunday.For this young group, everythings an opportunity, he said.Its great external noise (being a finals chance). It just means youre playing some good footy.Last time we played Carlton we got beaten so thats got to be our real focus.Roos added he was ready to end his coaching career.Im so pleased. Goody is going to be an amazing coach and the clubs in really good hands, he said.Its been a three-year build, there were a whole lot of issues.Its great to be part of it but a lot of other people have done an enormous amount of work to get the club back to where it is.Meanwhile, Roos was confident Jeff Garlett (skin infection) would train on Friday and be fit to face his former side.
