David Wright returned to Citi Field Tuesday, though it remains unclear when the third baseman will be back in the Mets' lineup.

Wright resumed baseball activities before the game against San Diego, fielding ground balls, throwing, running, and hitting. Spinal stenosis has kept the former all-star sidelined since mid-April.

"I've gotten to the point where I've done everything I could do rehab-wise. Now it's a matter of going out and testing it on the baseball field," said Wright, who had been working out in Los Angeles before rejoining the team in New York.

Manager Terry Collins said the team does not have a "timetable [for Wright's return] set down yet. Hopefully, we'll see here in the next seven days, eight days, that if everything moves forward, [he'll be able] to get in some [rehab] games. I think after that, once he starts playing, we'll have a better idea of how much we think he's going to need."

"[Today] will be my first day going back to back as far as baseball stuff at this intensity," Wright said. "I'll be ready when I'm ready. I'm not setting a date for rehab games until I get further along in the baseball stuff to understand that my body can take back-to-back, three days in a row, then four days in a row and so on.

"One of the biggest hurdles is that it's not really an injury, it's more of a condition," he added. "I think it's going to be something that has to be managed . . . It's just about managing what I have."

Wright said he hit in the batting cage, and fielded ground balls off the bat for the first time in the process.

"He's not limited," Collins said. "He actually threw the ball probably as good as you've seen him throw."

Said Wright: "For me, the challenge is every day, making sure to continue to get my rehab work in, along with the baseball stuff . . . I'm rushing it as much as I can. The last I want to do is rush it too much and have a setback."
