David Wright has started doing leg exercises, manager Terry Collins said before Tuesday night's game against the Braves.
Collins said the exercises have been designed to "get that hamstring working so we can certainly start some baseball activity soon.''

Wright, on the 15-day disabled list with a strained hamstring, is eligible to be activated April 30. But general manager Sandy Alderson reiterated Tuesday that Wright likely will need an extra week to be ready for a return. Given that timetable, he would miss about three weeks.
"He's advancing,'' Collins said. "He's right on schedule.''
In his third rehab appearance for Class A Port St. Lucie, Bobby Parnell allowed a run, two hits and two walks in two-thirds of an inning.
Injuries have thinned the Mets' bullpen, and getting Parnell back would help. The Mets remain hopeful he'll cap his comeback from Tommy John surgery by early May. But his fastball velocity is a work in progress, as is the sharpness of his curve. He has allowed three runs in 22/3 innings.
Robles called up
Hansel Robles made the most of a second chance -- as a reliever -- to reach the big leagues for the first time. Robles, 24, joined the Mets Tuesday night following a promotion from Triple-A Las Vegas, where he threw 72/3 shutout innings.
The hard-throwing righthander struggled so badly as a starter that the Mets removed him from the 40-man roster in 2013. He cleared waivers and began a new chapter as a reliever. Going to the bullpen, he said through a translator, gave his career "another life.''
