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.

Everyones asking about her future, but hot netball property Sharni Layton is determined to live in the present.The NSW Swifts defender will arguably be the most sought-after player for the new eight-team domestic competition in 2017.Her gung-ho attitude on the court combined with her breezy personality off it makes her very marketable.Layton is aware of all the talk and speculation about where she might play next year, but the Diamonds defender only wants to think about Sundays trans-Tasman grand final against the Queensland Firebirds in Brisbane.You just push it (the distractions) to one side, Layton told AAP.You know that those questions are coming and they come in all sports - it doesnt matter what sport you play.But its so important to be in the now and I do a lot of yoga and meditation.I love living in the moment and it is the last year of the ANZ Championship.Youve got next year to play next year and let that be.As the trans-Tasman competition draws to its cconclusion this weekend, Layton has pondered how her own career has taken off during its nine-season history.ddddddddddddn my first year at (Melbourne) Vixens in 2008, I was one of six players to not take the court, Layton recalled.I thought about quitting in 2009 and 2010 and moved to Adelaide and it all kind of took off from there.Layton has played in three grand finals, winning titles with Adelaide in 2010 and 2013, and was part of the losing Swifts side in last years decider against the Firebirds.Sometimes, I do have to absolutely pinch myself, Layton said.This week is my favourite week of the year because of the experience that Ive had in the past.Not everyone gets to play in a grand final; some girls go through their whole career without playing in a grand final.I know Im fortunate, this being my fourth, being able to enjoy that.
