“He has had, in (the) triceps area, a little bit of pain,” Collins said. “We shut him off the mound, made him throw long toss. That forces you to get your arm a little higher. He felt good and he threw batting practice the other day.
“After the second 20 pitches (in live batting practice), he said his arm felt like it was a lot of work and tricep was an issue again. We want to have him go get looked at.”
Niese was the Mets’ Opening Day starter last season, and was in line to start the season opener against the Washington Nationals on March 31st.
It’s worth noting that the Mets have a reason to be concerned with Niese’s shoulder, consider he missed a couple months last season with a partial tear in his left rotator cuff — he went on the DL June 21st and did not return until August 11th.
Niese’s shoulder was already a little tender when he came into camp, and then it flared up while throwing his latest live batting practice session.
Batting practice started and he felt fine,” Collins said. “And then he threw his second 20 pitches the other day. He just said at the end of it, ‘Geez, my arm’s just dead. Like, it’s dead.’
“It’s a precaution right now, but any time you’re sending someone for an MRI, obviously there’s going to be a concern until you get the reading back. He has had in the triceps area a little bit of pain. So we shut him down off the mound and made him throw long toss. That forces you to get your arm a little higher. And he felt good. And then he threw the batting practice the other day and in the second 20 pitches he said his arm just kind of felt like it was a lot of work.
“He just said he’s got a little discomfort in there. So we’re going to go have it looked at.”
