WASHINGTON -- Wilson Ramos jumped to catch a relay throw on a play at the plate that appeared pretty harmless. Only this time, his right foot hit the dirt and he crumpled to the ground, clutching his right knee.The All-Star catcher writhed in pain and was helped off the field during the Washington Nationals 14-4 loss to the Arizona Diamondbacks on Monday night. The injury could be another major blow to the NL East champions, already expected to be without ailing pitcher Stephen Strasburg in the Division Series against the Los Angeles Dodgers.Nationals manager Dusty Baker said Ramos would have an MRI on Tuesday to determine the extent of the damage. But the damage to the teams World Series hopes might already have been done.Theres nothing you can do about it, Baker said. Youve got to play and nobody feels sorry for you, so were not going to feel sorry for ourselves.It was the same knee Ramos injured badly during the 2012 season, when he tore his ACL and medial collateral ligament. Ramos, who can become a free agent after the season, is hitting .307 with 22 home runs and 80 RBI.Hes a silent leader, said starter Tanner Roark (15-10), who took the loss after allowing five runs and four hits in four innings. He goes out there and does it with his glove and behind the dish and his bat.The injury happened on Yasmany Tomas RBI double in the sixth when first baseman Ryan Zimmerman relayed home. Teammates immediately knew something was wrong with Ramos, who usually stays in the game after taking foul balls off just about every part of his body.Tough moment, said Roark, who is expected to follow Max Scherzer in Washingtons playoff rotation. Something just gave out and he pointed right to his knee.Ramos called for medical attention and couldnt walk off under his own power. Baker and players hoped for the best, but its clear they immediately feared the worst.You hate (for) it to happen this late, right before the playoffs, but our next step is try to figure out a way to play without Wilson, Baker said. Ive been mixing and matching this year and most of my life. Therefore, its another obstacle and Ive just got to try to go back to the drawing board and figure out something.The Nationals have two other catchers on their September roster in Pedro Severino and Jose Lobaton. But they dont have someone who can replace Ramos power and presence in the middle of the lineup.Washington should have reigning NL MVP Bryce Harper back by the playoffs, if not sooner, after Baker said X-rays came back negative on the sluggers left thumb. Baker said Harper could be back within a few days, and second baseman Daniel Murphy is expected to be in the lineup for Game 1 against the Dodgers on Oct. 7 after being shut down with a strained glute.Nationals pitchers allowed a season-high five home runs -- two to Jean Segura, a three-run shot to Tomas and one each to Mitch Haniger and Jake Lamb.Washington is one game up on the Dodgers for home-field advantage in the NLDS.BLAME THE RAINIncluding a 20-minute rain delay that started one pitch in, the top of the sixth inning took almost an hour to play. The Diamondbacks sent 11 hitters to the plate, scoring five runs on six hits with an error sprinkled in for good measure.TOMAS NIGHTTomas, a Cuban countryman of late Miami Marlins pitcher Jose Fernandez, made a running catch at the wall in the second inning and had a big night at the plate. Tomas was 2 for 5 with five RBI, including his 30th home run of the season.After Fernandezs death in a boating accident early Sunday at age 24, Tomas tweeted in Spanish calling Fernandez a friend and thanking him for the moments he provided in baseball. After the game he declined to talk about Fernandez.GOODWIN IN LOSSStarting in place of Harper, Nationals rookie outfielder Brian Goodwin hit his first major league triple and drove in two runs. With nothing but home-field advantage in the first round left to play for, Goodwin could see a lot of action the rest of the week.TRAINERS ROOMDiamondbacks: Manager Chip Hale said RHP Rubby De La Rosa will have a stem cell injection in his elbow Tuesday in an attempt to avoid a second Tommy John surgery.Nationals: LHP Sammy Solis was activated off the disabled list after missing more than a month with shoulder inflammation.UP NEXTScherzer (18-7, 2.82 ERA) continues his Cy Young Award campaign against Arizonas Matt Koch (1-1, 1.29), who will make his first major league start.Cheap Vapormax 97 .

They had already blown a double-digit lead, fans were hitting the exits, and a long seven-game road trip waited at the end.WASHINGTON -- John Tortorella sensed his players were tired of practicing and getting coached and were ready for the World Cup of Hockey.They played like it, too.The United States beat Finland 3-2 on Tuesday night in each teams final exhibition game before the World Cup begins this weekend in Toronto. Goaltender Jonathan Quick played well enough to earn the starting job for the first game of the tournament, and despite some late trouble the Americans looked prepared for the real thing.I think the boys feel tournament ready, said forward Max Pacioretty, who had an assist. That probably was the most comfortable weve felt.Quick made 30 stops, giving up a goal on a perfect shot by teenage phenom Patrik Laine and another on a scramble in front by Jussi Jokinen. T.J. Oshie, Ryan Kesler and Derek Stepan scored for the U.S., which went 2-1-0 in exhibition play and begins the World Cup on Saturday against Team Europe.Tortorella called it the Americans best of the three exhibition games and cited progress in several areas.We were cleaner, Tortorella said. Have we got it all figured out? No. And we probably wont get it all figured out. Its just not enough time to cover all the things wed like to cover, so we just keep on banging away here and see if we can get better each day.Pacioretty was much better than in two previous games, responding to Tortorellas comment that he needs more from the Montreal Canadiens forward. The new line of Pacioretty, Kesler and Oshie clicked, with Oshie appearing extra motivated playing in front of Washington Capitals fans.When youre at your home rink, you just feel comfortable, Oshie said. Always fun playing at home.Quick, a two-time Stanley Cup winner with the Los Angeles Kings, stopped 63 of the 66 shots he faced in exhibition play.dddddddddddd He put any doubt to rest about the U.S. starter, and Tortorella said Ben Bishop of the Tampa Bay Lightning would serve as the backup.A lot of things can happen in the tournament, but I believe in the body of work from all three goalies, Tortorella said. Its a really hard decision. I think Jonathan has just done a little bit better than the other guys, so hell be our No. 1 guy to start the tournament.Finland must still decide on its starter in net after Pekka Rinne of the Nashville Predators stopped 26 of 29 shots against the U.S. Itll be either him or Tuukka Rask of the Boston Bruins in Finlands opener Sunday against Team North America, but Rinne earned praise from coach Lauri Marjamaki.Pekka was great, said Marjamaki, who didnt name his starter for the first game. I like the style how he played. Of course he (faced a) couple of breakaways, so great game for him.Rinne robbed reigning NHL MVP Patrick Kane of the Chicago Blackhawks on a breakaway after a turnover by young Pittsburgh Penguins defenseman Olli Maatta, one of several Finns who struggled Tuesday.Laine, the No. 2 pick in the draft to the Winnipeg Jets, enjoyed his best exhibition game. The 18-year-old had four shots on goal, several nifty moves and his snipe past Quick.It is good for us and of course important goal for him, Marjamaki said. I think that his confidence getting better, and he can use his strengths in tournament.The big, physical U.S. team is ready to use its strength in the tournament after sharpening some things against Finland.Were getting better, Quick said. Every game were a little bit better, and well continue to get better. ' ' '
