Mets News and Notes:
New York Mets right-hander Shaun Marcum will undergo surgery next Monday in St. Louis to address numbness and coldness in his pitching hand and will miss the remainder of the season, assistant general manager John Ricco said Tuesday.
Manager Terry Collins said right-hander Carlos Torres will move into Marcum's rotation spot, at least until left-hander Jonathon Niese returns from the disabled list.
Torres may start Saturday against the Pittsburgh Pirates in place of Matt Harvey. The decision is unresolved, Collins said.
Harvey has been dealing with a blister, although Collins said Harvey reported improvement Tuesday. Another motivation for potentially skipping Harvey on Saturday is that the Mets are looking for ways to limit his innings count without shutting him down at the end of the season.
Four days after being designated for assignment, Brandon Lyon has been placed on release waivers by the Mets. Assuming unclaimed, Lyon will become a free agent.
Lyon, 33, was 2-2 with a 4.98 ERA in 37 relief appearances.
