Mets second baseman Neil Walker (hamstring tear) will begin playing rehab games soon, manager Terry Collins said on Friday.
Walker took batting practice on Thursday for the first time since suffering the injury.
He recently resumed baseball activity and is in the beginning stages of running, he told reporters Wednesday.
Walker, who was placed on disabled list on June 15, is pleased with his progress thus far.
"It's going the way we hope," Walker said. "There is no timetable, all going to be dependent on how it responds and how things look in the next week or so.
While Walker doesn't have an exact estimate on when he'll return to the lineup, he did say he'll ramp up his running efforts soon.
"If the next several days go well we might progress a little more. If I'm sore, we'll back off. There is no timetable," Walker said. "It's all dependent on how things go in the weight room and how things go with the strength and stability and then we'll see."
Walker has hit .270 with nine home runs and 33 RBI through 60 games in his second season in New York.
