#Mets rookie pitcher David Peterson dodges big injury bullet

A day after the rookie was scratched from his start against the Marlins with shoulder discomfort, an MRI exam on Wednesday indicated that Peterson has “minor inflammation” in the joint, but no structural damage. Peterson will rest for the short term.

“I’m not worried about it,” Peterson said before the Mets beat the Marlins 5-3 in Miami.

As it stands the Mets have Rick Porcello and Robert Gsellman lined up for the first two games of the Subway Series this weekend at Citi Field with a question mark surrounding Sunday. With his IL stint backdated, Peterson could theoretically be a possibility for that start, but that seems like a stretch.

Michael Wacha, who is also recovering from shoulder inflammation, threw in a simulated game Tuesday and the Mets are waiting to determine his next step.

Peterson, who owns a 2.91 ERA in four starts, has been among the team’s bright spots this season.

“The starts I have had already have been good experience for me and there were things to learn and things to take away that were positives and so I don’t see this as a big block in the road,” Peterson said. “I am going to take the experience that I’ve had and keep learning when I get back in the rotation.”

Jeff McNeil’s left knee isn’t as much the issue as maybe a change to his approach.

The Mets outfielder was on the bench for a mental cleansing of sorts, as his recent slump had continued following a return to the lineup from a left knee contusion.

“[McNeil] was moving OK, there was nothing he was complaining about, just for him a day off, we have some things to work on with him,” manager Luis Rojas said before the game. “He was a little different at the plate [Tuesday], a little bit more upright with his stance and some things and his approach. We want to make sure he’s right back on track with his hitting.”

McNeil entered 1-for-11 (.099) since returning to the lineup Monday following his collision with the left-field fence last week. Overall he was in a 6-for-32 (.188) skid over his previous 10 games.

Andres Gimenez is dealing with a sore right ankle after fouling off a ball in recent days, but Rojas indicated it’s not a concern.

“He squared it up pretty good,” Rojas said. “We gave it some time, but there is nothing really we could do, he has been getting his playing time coming in as a sub, but there’s no concerns, he is good.”
