LOS ANGELES (AP) — The New York Mets placed catcher Francisco Alvarez on the 10-day injured list Saturday with a sprained left thumb sustained while running the bases the night before in a 9-4 victory against the Los Angeles Dodgers.

Manager Carlos Mendoza said the team still was waiting for results of an MRI performed late Friday night “but we know for sure it’s going to more than 10 days.”

The 22-year-old Alvarez left Friday night’s game after jamming his left thumb in the second inning when he put his hand down to try and keep his balance coming around first after a bad throw by catcher Will Smith.

“You hate to see it,” Mendoza said. “We don’t know how long he’s going to be out for but we know how much energy he brings and the way he was playing. But at the same time, next guy up. It’s an opportunity for other guys to step up.”

The manager said Alvarez was “frustrated, obviously, and still waiting to see what they find. He’ll get through it. He’s a strong kid. He’s very positive. He will be fine.”
