The New York Mets say slugger Pete Alonso has a bone bruise and sprain of his left wrist and is expected to be out 3-4 weeks.

He's been placed on the 15-day injured list in a move that is retroactive to Thursday.

"We got better news than it could have been," New York manager Buck Showalter said. "So we take that as a positive. It could have been worse."
