David DeJesus hit a bases-loaded triple before injuring his shoulder when he crashed into the outfield wall, and the Chicago Cubs beat the New York Mets 6-3 on Friday night behind resurgent starter Edwin Jackson.
Nate Schierholtz homered and Anthony Rizzo had three hits for Chicago in the opener of a three-game series between big-market teams trying to rebuild. Jackson (3-8) went six innings for his second consecutive win, allowing one run and five hits while striking out seven.
Mets starter Shaun Marcum (0-8) was hit hard early but retired 12 straight during one stretch and pitched into the sixth. It was his first outing since throwing eight innings of splendid relief in a hard-luck loss to Miami on Saturday, when the Mets were beaten 2-1 in 20 innings.
Daniel Murphy hit two RBI singles and David Wright had three hits for the second consecutive game, but his baserunning blunder stopped a Mets rally in the seventh. New York has lost nine of 11 since a five-game winning streak.
Coming off a 14-inning victory Thursday at home over Cincinnati, the Cubs won their second in a row after dropping eight of 10.
Rizzo's bloop single started a four-run second. Dioner Navarro also singled and a walk to Luis Valbuena loaded the bases with none out.
After a visit from pitching coach Dan Warthen, Marcum gave up an RBI single to Darwin Barney before Jackson struck out. DeJesus then hit a drive beyond the reach of rookie center fielder Juan Lagares that banged off the right-center fence for a three-run triple, giving Chicago a 5-0 cushion.
One inning later, Lagares led off with a triple to nearly the same spot and DeJesus — running almost full speed — crashed hard into the wall while trying to make the catch. He extended his right arm but the ball ticked off the end of his glove, and DeJesus' prone right shoulder slammed into the padded wall.
His glove was knocked off his hand, and DeJesus immediately went down, writhing in pain on the warning track as he reached for his shoulder.
After Lagares pulled into third, every Cubs fielder went out to the warning track to aid DeJesus along with manager Dale Sveum, a trainer and a worker in an EMS top. But in an encouraging sign, DeJesus got up and walked off the field under his own power, his right arm hanging limp along his side.
Ryan Sweeney took over in center field, and the Cubs said DeJesus was having X-rays on his right shoulder.
DeJesus, who grew up nearby in New Jersey and went to Rutgers, had family in the stands, a team spokesman said.
Lagares scored on Murphy's two-out single, but Valbuena chased Marcum with a two-out RBI double in the sixth that made it 6-1.
New York got run-scoring singles in the seventh from Murphy and Lucas Duda off James Russell, but Wright was cut down at third by Alfonso Soriano's throw when he tried to go first to third on Duda's one-out single to left.
Carlos Marmol worked a perfect eight and Kevin Gregg got three quick outs for his eighth straight save to begin the season.
With two outs in the first inning, Schierholtz homered into the front row of the second deck in right field, where an excited fan caught the ball on the fly.
Schierholtz has gone deep in four of his last eight starts and matched his career high of nine home runs with San Francisco in 2011. He was moved up to third in the lineup, with Rizzo dropped to the No. 5 spot.
"I'm just kind of mixing it up. Right now you could say he's our best hitter," Sveum said about Schierholtz, who has a seven-game hitting streak.
