Mets second baseman Neil Walker has a partially torn left hamstring and has been placed on the 10-day disabled list, the team announced Thursday.
Walker, who exited Wednesday's game due to the injury, was replaced on the 25-man roster by INF Gavin Cecchini, who was called up from Triple-A Las Vegas.
The hope is that Walker -- who received a platelet-rich plasma injection -- will be able to begin rehabbing the injury in two or three weeks, GM Sandy Alderson said.
Walker pulled up lame and grabbed his left leg while trying to beat out a bunt in the third inning. He was replaced in the lineup by Lucas Duda, and T.J. Rivera slid over from first base to second.
Walker is hitting .270 this season with nine home runs and 33 RBIs.
