NEW YORK -- The Chicago Cubs count on David DeJesus to create runs. Trying to save the Cubs some runs will cost the team his services for at least two weeks.
DeJesus had a three-run triple in the second inning but left with a right shoulder sprain after crashing into the wall trying to catch Juan Lagares' triple in the third inning of the Cubs' 6-3 win over the Mets on Friday night at Citi Field.
The Cubs announced immediately after the game that DeJesus would be placed on the disabled list. The club will announce a corresponding roster move before Saturday's game.
"Obviously came through with a huge hit and then made a balls-out play and paid for it at the end," Cubs manager Dale Sveum said. "Almost made a heckuva catch."
DeJesus' shoulder remained swollen after the game and he'll need to undergo another MRI once the swelling goes down.
"I'm happy that there's no broken bones," DeJesus said. "We'll see how it goes. We'll get back to Chicago, the doc's there, get an MRI and go from there."
Lagares, who barely missed chasing down DeJesus' triple in the second, hit his triple to almost the exact same spot of the field. The ball eluded DeJesus, who then hit the wall so hard that his glove fell off.
He immediately began writhing in pain on the warning track as Sveum, trainer P.J. Mainville and every Cubs player on the field except the battery of Edwin Jackson and Dioner Navarro ran out to DeJesus' aid.
"It was just like the pressure just didn't want to stop," DeJesus said.
After several minutes on the ground, DeJesus walked off the field mostly under his own power, though his right arm was slung over the shoulder of Mainville.
"That's kind of the player he is," Sveum said. "He plays hard every day and unfortunately that fence got the best of him today."
DeJesus, whom the Cubs signed to a two-year deal after the 2011 season, is hitting .260 with six homers, 21 RBI and 32 runs scored in 59 games this year. The Cubs are 12-13 when he scores a run this season and 15-25 when he doesn't.
"Huge part of our lineup," Sveum said. "When he's going and getting on base, that's usually when we score."
The injury to DeJesus overshadowed the Cubs' second straight win -- their first back-to-back wins since a season-high five-game winning streak from May 26 to May 31 -- and a second straight strong performance by Jackson, who allowed one run, five hits and three walks while striking out seven in six innings.
It was the second consecutive win for Jackson (3-8), who struggled during the first two months of the season after signing a four-year, $52 million contract in January. He has allowed just two earned runs in his last two starts, a 13-inning stretch in which he has lowered his ERA from 6.29 to 5.23.
"Just trying to get in a rhythm," Jackson said. "Tonight it would have been nice to go a little deeper, help the bullpen out a little more."
Sveum said Jackson has relied more on his natural stuff the last two starts.
"You can see the conviction in the pitches, not worrying about trying to be a pitcher as much as just a stuff guy -- get guys out with his stuff and not trying to pitch so much," Sveum said.
Nate Schierholtz homered in the first inning -- his fourth homer in his last eight starts -- to give the Cubs a lead they never relinquished before DeJesus' triple capped a four-run second.
Anthony Rizzo had three hits. Dioner Navarro had two hits and Darwin Barney and Luis Valbuena each had an RBI.
Cubs reliever James Russell allowed two runs in the seventh before Carlos Marmol threw a perfect eighth and Kevin Gregg picked up his eighth save with a 1-2-3 ninth.
The Mets (24-38) fell to 1-5 on an eight-game homestand.
Daniel Murphy had two RBI singles and David Wright reached base in all four plate appearances (three singles and a walk) for the Mets, who left eight runners on base and stranded two runners in each of the third, fourth and fifth innings.
Shaun Marcum fell to 0-8 -- tied for the third-worst start in Mets history -- after allowing six runs, seven hits and one walk with four strikeouts in 5 2/3 innings. Marcum retired 12 in a row after DeJesus' triple and threw 82 pitches, 23 fewer than he had in his eight-inning relief stint on Saturday in the Mets' 2-1, 20-inning loss to the Miami Marlins.
With prospect Zack Wheeler about to reach the majors, the Mets are employing a six-man rotation for the next turn or two, but Marcum appears to be the most vulnerable pitcher once the Mets return to a five-man rotation.
"I think Shaun is a he's a professional, he knows you've got to go out and get the job done," Mets manager Terry Collins said. "He's very upset about the way he pitched tonight, but he has pitched very well. He just got off to a bad start."
NOTES: The Mets played their 35th home game of the season and drew their fourth-biggest crowd -- 32,208 -- on a night in which the band Foreigner played a postgame concert. ... Collins said before the game that Zack Wheeler, the club's top prospect, will start the second game of Tuesday's day-night doubleheader against the Braves in Atlanta. Wheeler will be making his major-league debut and Collins said he wanted Wheeler to be on a more normal routine, as opposed to having him start the 1 p.m. game. Matt Harvey will start the early game for the Mets. ... LHP Johan Santana, who is out for the year after undergoing surgery to repair a tear in his left shoulder capsule, visited the Mets before the game. It was the second shoulder capsule tear and surgery for Santana, but Collins said Santana feels better now than he did at the same point in his rehab from the first surgery and that he wants to pitch again. ... The Cubs activated RHP Henry Rodriguez, whom they acquired from the Washington Nationals on Tuesday, and optioned LHP Brooks Raley to Triple-A Iowa. ... Navarro and Mets counterpart John Buck had an amusing moment in the fourth when Navarro lost track of Marlon Byrd's popup. Navarro covered his head as the ball bounced off a wall right behind an unknowing Buck, who was in the on-deck circle. Buck gave the ball to a fan.
