WASHINGTON -- The Washington Nationals placed Gio Gonzalez on the 15-day disabled list Sunday because of inflammation in his pitching shoulder. Jose Quintana Jersey . This is the first time the 28-year-old left-hander has gone on the disabled list. Gonzalez (3-4) dropped his third straight start in Saturdays 5-2 loss to the New York Mets. He lasted only three innings, allowing five runs and seven hits, which raised his ERA to 4.62. Gonzalez gave up seven runs and nine hits in his previous start at Oakland. General manager Mike Rizzo said Gonzalez had an MRI on Sunday in which dye is injected. He will not be able to throw for five days. "Hell miss two starts," Rizzo said of the initial plan. "Well find out whats going in (Gonzalezs shoulder) and take it from there." The Nationals recalled Ryan Mattheus from Triple-A Syracuse. Gonzalez left a start in late April because of shoulder tightness. "He passed a strength test. Combined having a little soreness (Saturday) with a little soreness a month ago, we thought this was a prudent way to do it," Rizzo said before Sundays series finale with the New York Mets. Gonzalez side-stepped questions about his health Saturday, but spoke with Rizzo following his latest loss. "I dont have a great concern level for it right now just because the way Gio said he felt after the game," Rizzo said. Gonzalez lost command of the strike zone Saturday, falling behind in the count and throwing 84 pitches in three innings. "I thought he looked fine," said Rizzo about whether he saw an injured pitcher on the mound. "His arm speed was good. His spin was fine. As good as its always been on his breaking ball. His fastball velocity was good. The command part of it, which sometimes comes and goes with Gio anyway, was the thing that was causing him an issue." Gonzalez went 32-16 during his first two seasons with the Nationals after a trade with the Oakland As. He made at least 32 starts in each of his previous four seasons. "Hes a big key to the ball club," Rizzo said. "Wed like to get him back. Were going to take our time with him and be careful with him because hes vital to the ball club." Mattheus has 140 career appearances with the Nationals, including two this season. He has not allowed a run in three innings. Rod Beck Jersey . Mesoraco hurt his hamstring while scoring from second in Friday nights 5-4 loss at Atlanta. Chapman was hit by a line drive during an exhibition game on March 19, breaking his nose and a bone above his left eye.

Vargas (8-3) allowed four singles and two walks while striking out five, allowing only two runners from a diluted Twins lineup to reach second base. Mike Moustakas and Jarrod Dyson hit RBI singles in the second inning against Kevin Correia (4-10), and that was all Vargas needed.BROSSARD, Que. -- Aaron Ekblad says no one has a right to expect a spot on Canadas world junior roster, even those players returning for a second tour of duty. The first overall pick in this summers NHL entry draft said that a fourth-place finish at least years world junior championship means everyone vying for a spot on the Canadian squad to play on home soil later this year is on equal footing -- himself included. "Theres something left on the table," said Ekblad of the opportunity squandered in Malmo, Sweden that ended abruptly with a bronze medal game loss to Russia. "Obviously were coming into this with positivity, but we lost last year," added Ekblad, a defenceman for the Ontario Hockey Leagues Barrie Colts. "None of us, I think, have earned the right to say we deserve a spot again." Head Coach Benoit Groulx says thats exactly what he wants to hear. "Thats the attitude we like -- hes coming here as the first pick overall and hes first on every drill and hes probably the hardest working player on the ice," said Groulx, the Gatineau Olympiques coach who served as an assistant-coach for Canada in Sweden. Ekblad is among 39 players in suburban Montreal this week taking part in development camp that runs until Aug. 8. The Canadian players will play in exhibition games in Sherbrooke, Que. and at Concordia University in Montreal against teams from Russia and the Czech Republic. Groulx says he wants to see how players will adapt to what theyre being taught during practice and how theyll put those lessons to the test during games. Everyone will get a chance to play. "We want to be a team, we want to play as a team, we want four lines going hard, playing the same way," Groulx said. "This is our challenge and this is their challenge to be fitting on this team in a specific role." The coach said this week is just the first step in a very long process to decide on who will make up the Canadian squad that will play at the world junior championship in Montreal and Toronto at the end of the year. Ekblad is among a group of ten players at the camp who are back. The group also includes fellow first-round pick Sam Reinhart and young phenom Connor McDavid, the only draft-eligible player among them. Groulx had praise for all returnees who have been exhibiting leadership qualities since camp began Sunday night. Keith Moreland Cubs Jersey. "Theyre here, you can tell their ready and they dont take anything for granted," Groulx said. For McDavid in particular, its expected to a pressure-packed year. The Erie Otters forward is projected to be a top NHL draft pick in 2015. McDavid says hes got plenty of people around him keeping him grounded and helping him keep the focus on the task at hand. "At the end of the day, youre here for the world junior championship and nothing else," the soft-spoken McDavid said. "Youre not here for your draft stock or anything like that, youre just here to represent Team Canada and thats it." Canada hasnt won a gold medal in since 2009, when it won its last of five straight. The country hasnt had a medal since 2012 and has back-to-back fourth place finishes in the past two years. "Even to this day, I know a lot of the returning guys are disappointed and have the drive and fire to improve on last year," said Reinhart, a first-round pick of the Buffalo Sabres. "If we were all privileged enough to play, I know everyone is going to be motivated to get the best result possible." The 11-day tournament in Montreal and Toronto opens on Boxing Day and runs to Jan. 5, with the final at Air Canada Centre in Toronto. Its up in the air how many of the players at camp this week will still be eligible to play come December. Many, like Ekblad, expect to challenge for NHL spots. In the case of this years first overall pick, Ekblad made it clear he wants to secure an everyday spot on the Florida Panthers. But he assures that hell be ready and willing if he ends up suiting up for Canada. "We dont know whats going to happen with him (Ekblad) but one thing we know is that if hes with us at Christmas time, hell have the respect of his peers, which is key, and the respect of his coaches," Groulx said. NOTES: Thirty-nine players of the 41 players invited are expected on the ice this week. The exceptions are Tampa Bay Lightning prospect Jonathan Drouin, who isnt obliged to be here because it is his third invite. Vancouver Canucks prospect Jake Virtanen is present but is recovering from an injury and wont be on the ice. Tyler Bertuzzi didnt dress Monday due to illness. ' ' '
