Justin Turner said he was unnerved witnessing a 10-year-old boy getting struck in the face with a foul ball off the bat of Florida’s Greg Dobbs during the ninth inning of Game 1 of Monday’s doubleheader.

Turner gave his jersey to the family.

“It hit him right between the eyes,” Turner said. “It’s probably one of the baddest things I’ve ever seen on a baseball field. I saw it hit him. He didn’t move. I heard his mom screaming. I looked over. Blood was squirting out of his forehead onto his mom. It was pretty disturbing. I haven’t heard yet if he was all right or not, but he was talking when they were wheeling him through here. …

“I saw the whole thing. I don’t even think he moved. Some guys in the front row I think jumped up for it and probably blocked him from even seeing it. It didn’t even look like he flinched or moved or anything. It hit him square. I felt sick to my stomach. I talked to Nick (Evans). He was right next to me. He saw the whole thing too. Both of us felt pretty sick to our stomachs when we saw it. You never want to see anything like that happen, especially to a 10-year-old kid.”

Dobbs told reporters on the Florida side postgame that he was told that the young man’s vision was not affected.

NO JITTERS: Bobby Parnell entered the day with two career major league saves. Had Mike Nickeas’ eighth-inning RBI not given the Mets a four-run cushion in Game 2, Parnell might have doubled that total Monday.

Parnell allowed a solo homer but nonetheless closed out the opener. He then tossed a scoreless ninth in the nightcap to complete the 5-1 win.

Terry Collins said he used Parnell in the non-save situation in Game 2 because he was already warm. Jason Isringhausen likely will close Tuesday if the Mets have a late and narrow lead.

“The nerves weren’t near as bad this time,” Parnell said, contrasting Monday’s Game 1 appearance with an Aug. 24 save at Philadelphia. “I knew what I had to do. I was more concentrated on that. It was definitely easier.”

Common sense dictates the Mets preferred Nickeas drive in the tack-on run. But did any part of Parnell want a three-run lead entering the ninth and two saves in one day?

“It would have been fun, for sure, but at this point we’ll take every run we can get and every win we can get,” Parnell said. “As long as I’m throwing in the ninth and getting that experience, it’s good.”

SHOULDERING LOAD: Jason Bay, who played Game 1 of the doubleheader after a three-day layoff, said his right shoulder felt fine. Bay had been scratched from Friday’s game against Atlanta.

He did not play in Monday’s nightcap -- Willie Harris started in left field -- but Bay suggested that was about it being unwise to play 18 innings the first day back from an injury. Bay originally jammed the shoulder attempting a diving catch last week in Philadelphia.

“I don’t think it should be an issue going forward,” Bay said.

NICK KNOCKS: Evans had two hits in each game of the doubleheader and is hitting .526 (10-for-19) with five RBIs in his five starts at first base since Lucas Duda has resettled in right field.

“I’ve never really gotten to play this many days in a row, so it’s exciting,” Evans said. “I love it.”

Evans, incidentally, is mulling playing winter ball with Caracas in Venezuela. That’s the team for which Duda is likely to play. It will be managed by Tim Teufel, who succeeds Dave Hudgens in that role.

SWEEP: The Mets notched their first doubleheader sweep since April 27, 2010 against the Los Angeles Dodgers. ... Duda lost a seven-game hitting streak. ... Mets starters had tossed 25 1/3 scoreless innings until Dillon Gee surrendered a solo homer to Greg Dobbs in the sixth inning of Game 2.
