The injuries continue to pile up for the Mets, who placed first baseman Pete Alonso on the 10-day injured list with a right hand sprain and right-hander Tommy Hunter on the 10-day IL with lower back pain on Friday. The Mets currently have 16 players on the injured list.

The Mets recalled Yennsy Díaz and selected Brandon Drury’s contract from Triple-A Syracuse to round out their active roster ahead of Friday’s game against the Marlins. To make room for Drury on the 40-man roster, Daniel Zamora was designated for assignment.

Alonso was hit by a pitch on May 5 against the Cardinals, but he continued to play until he was given the day off on Wednesday against the Braves. He was hoping to be back in the lineup Friday against Miami, but he said the hand hasn’t felt normal. 

Since being hit by the pitch, Alonso had gone 5-for-41 (.122) with a home run and three RBIs. He said the Mets knew about the injury the moment it happened, but he decided to grind it out until Wednesday. The hand injury did not affect his defense, but he felt the pain while swinging the bat.   

Alonso doesn’t know how long he will be out, but he hopes to be activated by the end of the month when the Mets play the Braves at Citi Field.   

“I haven’t felt myself. Granted so. I got hit on the hand [with a 98 mph fastball],” Alonso said. “With that being said, we did a lot of treatment. We got pretty much all the swelling out. I’ve been doing a lot in the training room. The training staff has been absolutely incredible. … 

“If I want this thing to completely go away and get better, I’m going to need to give it a rest. I have to listen to my body. I’ve been grinding. I’ve been doing the best I can out there. I’m at the point also where if I’m continuously going out there with just a version of myself -- not normal -- it doesn’t help the team in the long run. It’s not going to help my body in the long run.” 

With Alonso out, Drury is in the starting lineup at first base. Before the promotion, Drury was with Syracuse, hitting .192 with two home runs and four RBIs. 

Hunter, who collected his first big league hit against the Braves earlier this week and has been a staple in the bullpen, has a history of back pain. He had an MRI on Friday, but the Mets do not know the results. 

“With his back history, we want to make sure he is OK,” manager Luis Rojas said. 

Díaz will be Hunter’s replacement on the roster, and he will also work out of the bullpen. Diaz has pitched three innings for Syracuse without allowing a run. 

Since May 11, the Mets have lost Jacob deGrom (right side tightness), Albert Almora Jr. (left shoulder contusion), Michael Conforto (strained right hamstring), Jeff McNeil (strained left hamstring), Kevin Pillar (multiple facial fractures), Taijuan Walker (left side tightness), Alonso and Hunter to the IL.

Carlos Carrasco (torn right hamstring), Noah Syndergaard (Tommy John surgery), Seth Lugo (right elbow surgery), J.D. Davis (left hand sprain), Brandon Nimmo (left index finger bone bruise), José Martínez (left knee surgery), Luis Guillorme (right oblique strain) and Dellin Betances (right shoulder impingement) are on the IL as well.

The good news is, deGrom, Davis and Syndergaard are on rehab assignments. deGrom is scheduled to pitch on May 25. It’s unknown if he will pitch in the Minor Leagues or against the Rockies. 

“I want to say we hope [he pitches in the Major Leagues], but we want to see this day to day,” Rojas said about deGrom. “Today, he came in early, he had his treatment. Tomorrow, he has a touch and feel and then on Sunday, he will have [a bullpen] session. We want to see the day to day.” 

Davis is going to play first base during his rehab stint with Triple-A Syracuse. They hope he could be back with the team within a week. 

Worth noting

The Mets announced updated health and safety regulations for fans at Citi Field that will take effect beginning with the team’s next homestand, starting on May 24. Starting that day, fans will no longer be required to show proof of a negative COVID-19 test to enter Citi Field. 

The Mets will open 21 seating sections to fully vaccinated fans that will be free of social distancing rules. Those 21 sections will hold a total of 3,870 fans, bringing the total capacity at Citi Field to 12,222 fans. 

Tickets in fully vaccinated fan sections are available for purchase now at mets.com/VaccinatedSections. These sections are reserved for fans ages 16 and older who are at least 14 days removed from their final dose of any of the three COVID-19 vaccines (Pfizer, Moderna or Johnson & Johnson). While seated in fully vaccinated sections, fans will not be required to wear a mask. Face coverings are still required outside of fully vaccinated sections. All fans with seats in a fully-vaccinated section must enter the ballpark through the Bullpen Gate and are responsible for providing proof of vaccination. 

The Mets are offering vouchers, good for two tickets to a future Mets game (blackout dates apply), to the first 250 fans who receive either dose of the Pfizer COVID-19 vaccine at Citi Field each day during the team’s next two homestands (May 24-30 and June 11-17). Fans may instead choose to receive a complimentary ticket to the game on the same day they receive the vaccine, based on availability.
