Fan injured after falling onto field at Citi

NEW YORK -- A fan was injured after falling from Citi Field's "Party City Deck" in left-center and onto the playing field during batting practice on Saturday.

Witnesses said the fan -- Nick Gambacorta, 32, of Staten Island -- was leaning over the railing trying to get the attention of Giants players roaming the outfield about an hour and a half before first pitch.

"[Gambacorta] was leaning over, and as he leaned over, his momentum made the mat slide out from underneath him," said witness Joe Piacentino Jr. "That's how this happened. He wasn't reaching for a ball that was being hit."

Paramedics attended to Gambacorta before taking him off the field on a stretcher. There was no official word on his condition.

The Mets issued the following statement: "A fan fell from the left-field stands and was taken to the hospital."

Gambacorta and Piacentino were among a group of MTA workers at Citi Field for a group outing.

Collins hoping Wright can snap out of slump

NEW YORK -- Typically, when David Wright slumps, Mets manager Terry Collins does not fret. More than any other player on his team, Collins believes in Wright's ability to self-diagnose and correct whatever mechanical issues ail him.

This latest slump, however, has Collins worried. Relatively speaking, Wright has not hit much all season. He entered Saturday's play with the lowest on-base and slugging percentages of his career, the latter mark by a significant margin. He did not make the All-Star team for the second time in his career.

As a result, Collins can't help but wonder if the right shoulder issue that sidelined Wright for a week in July is still affecting him. Wright received a cortisone injection in his shoulder just before the All-Star break, but has hit .170 with a .430 OPS since.

"I know he gets treatment on it," Collins said. "Now is it still bothering him? I really haven't talked to him about it. I know that he had the shot before the All-Star break. And I saw him in San Diego [to open the second half], and he said he felt great. I haven't really got into it much. There's no telling. It could be bothering him a little bit."

Rarely admitting when he is injured, Wright famously played through a stress fracture in his lower back for several weeks in 2012. He attempted to do the same while nursing a sore hamstring last August, ultimately tearing the muscle and missing most of September. Collins fears an injury could be at the root of Wright's current issues, as well.

"I'm concerned with the fact he's not hitting," Collins said. "I'm not sure about the physical side. Before he got hurt, he was slumping a little bit, too. I don't know if he's trying to drive the ball, but his swing has gotten just a little long. I know that he was in the cage yesterday, he was in the cage earlier today trying to shorten it up. Hopefully, it pays off, because ... those guys, when they come out of it, they get hot."

Worth noting

Collins said there has been "a lot of talk" about promoting outfielder Matt den Dekker to the Majors, considering den Dekker's .329 average and .931 OPS at Triple-A Las Vegas -- both ranking in the top five in the Pacific Coast League. But so far, the Mets have not made a move, as doing so before September would require them to take someone off the 25-man roster.
