As Edwin Díaz was warming up to pitch the ninth inning of Sunday’s wild 8-7 win at Citizens Bank Park, he started feeling some soreness in his back.

“It started when I was warming up in the bullpen,” said Díaz via the Mets’ team translator. “I usually don't warm up at 100% in the bullpen. I usually wait to get to the mountain to finish warming up. But as the game went on, as I kept throwing pitches, it started to get tighter and tighter.”

After just 28 pitches, the back pain was too much for the reliever, and he was pulled from the game. Though this type of pain hasn’t happened before, Díaz doesn’t believe it is anything serious.

“It was probably that I just slept the wrong way,” Díaz said. “I've been working with the trainers all day today. I went out, I threw [and] I feel much better. I feel like I have more power. Now, I'm able to finish my pitches when I'm throwing. It does look good for tomorrow or the next day.”

Manager Luis Rojas knows that through an entire 162-game season, no one is going to feel 100 percent all the time, but he stressed that an open line of communication between him, his players and the coaching staff is vital to keeping players like Díaz off the IL.

“We're playing a night game, landing here at three in the morning, not getting as much sleep,” said Rojas. “You're beating up your body, and we want to be smart towards the workload that we put on the guys, but there'll be some soreness that guys are going to play through, those [that guys] are going to push through. He probably felt that he could come in and pitch through it, but he got worse.”

Updates on Nimmo, Davis
Injury woes continue to be a concern for the Mets, but Rojas believes that both J.D. Davis and Brandon Nimmo are improving. However, the process is slow for both.

On Monday, Davis was added to the 10-day IL retroactive to May 2nd. The prognosis is positive, but the team is still evaluating what he can do due to the sprain in his left hand.

Nimmo was left out of Monday’s starting lineup due to a bruised left finger. He will be able to sub in on defense and run, but his ability to hit is questionable according to Rojas.
