PHILADELPHIA — Jeff McNeil has a healthy new baby girl and a healthy right wrist. He’s a “happy Jeff” once again, but he could be happier. Should the Mets eliminate the Philadelphia Phillies in the ALDS and advance to the next round of the postseason, it’s likely McNeil could be on the roster. The super utility man rejoined the team Sunday in Philadelphia, impressing the Mets with how much work he put in while he was in California rehabbing from a wrist fracture and waiting for his wife, Tatiana, to give birth to the couple’s second child, a daughter named Serena. “I want to be ready to play,” McNeil said Sunday at Citizens Bank Park before Game 2 of the NLDS. “I know there are a few more steps that I need to take care of in order to be ready, so we’ll work on that. It’d be just kind of a day-to-day thing. When my time is called, I’ll be ready.” McNeil was allowed to go home to California during the final home stand. The Mets trusted him to work out and do physical therapy on his own, and he made good on that promise. Immediately upon arriving in Philadelphia, he underwent a full workout, participating in team stretch, playing catch, taking ground balls and fly balls, running the bases and taking batting practice in the cages. In addition, he tracked some pitchers in the bullpen. “I don’t have any pain there right now, it’s more just getting the range of motion back,” McNeil said. “That’s all feeling really good. So we’re at the point where I’ve been doing baseball activities. I’ve been swinging the bat the last week or so, and taking ground balls, running and just getting back into that baseball shape.” McNeil has only been down for about a month, so he’s been able to maintain his season form. He’ll need to face live pitching before returning to get a sense of the timing of the pitches and to make sure his wrist can handle in-game swings, which he thinks he can do at Citi Field with the pitching machine. The 2022 NL batting champ is not worried about timing. Even in spring training, he never needs very many at-bats to get his timing down. His timing sure was looking good in the second half of the season, when he shook off a sluggish start to hit .289 with a .932 OPS, 12 doubles and seven home runs in 37 games. The wrist was injured last month when he was hit with a pitch, but X-rays show that the fracture has completely healed at this point. Still, he’s way ahead of schedule. “I know I’m definitely farther along,” he said. “I think what they planned for me was just 4-6 weeks. I think we’ve had four weeks, so I feel good. I’ve been hitting and I’m feeling good. While McNeil is pleased with how the timing of everything worked out, it’s clear he’s eager to get in on the postseason action. He watched the Mets clinch a playoff spot in Atlanta from his house. He was “going nuts” after Francisco Lindor hit his late home run. Game 3 of the Wild Card against the Milwaukee Brewers was played the night before Serena was born, with Jeff and Tatiana watching from the hospital. He tried to celebrate Pete Alonso’s clutch home run as quietly as he could. “I remember sitting in the hospital bed with my wife, and he comes up in a situation. I go, ‘Maybe a little run right here,’ and I knew I was going to go crazy,” McNeil said. “She goes, ‘Don’t go crazy. They’re going to think I had the baby right here.’ I tried to contain myself. It was a pretty, pretty special moment.” Since the Mets didn’t have a rowdy clubhouse celebration in 2022, the homegrown members of the team like Alonso and Brandon Nimmo had never been able to participate in one of baseball’s best traditions until last week. McNeil missed out on two and he doesn’t want to miss another. The Mets would pay the winner of the San Diego Padres-Los Angeles Dodgers series in the NLCS. McNeil always plays well in California, having grown up rooting for the Dodgers and playing college baseball at Long Beach State. The San Diego schools are frequent opponents for the Dirtbags. But before he can think about what’s next, he might want to sleep a little bit more. “The hospital cot or whatever it is was horrible,” McNeil said. “I actually got to spend about two hours in bed this morning, which was pretty magical.”
