WASHINGTON (AP) -- The New York Mets purchased the contract of right-handed pitcher Chris Young from Triple-A Buffalo and he was set to start Tuesday night against the Washington Nationals.

Young was 1-0 with a 2.35 ERA in four rehab starts. Last May, Young underwent shoulder surgery.

The Mets also activated right-handed pitcher Miguel Batista from the 15-day disabled list. He'd been sidelined with a lower back strain.

New York placed right-handed pitcher Ramon Ramirez on the 15-day DL with a strained right hamstring. Ramirez injured the hamstring running in from the bullpen to join in the celebration of Johan Santana's no-hitter on Friday, manager Terry Collins said. Ramirez is 2-1 with a 4.78 ERA and one save.

The Mets also designated right-handed pitcher Jack Egbert for assignment.
