The New York Mets have placed right-hander Chris Young on the disabled list because of tightness in the back of his right shoulder.
The team has called up left-hander Pat Misch from Triple-A Buffalo to replace Young.
Young was not able to make his start on Saturday because he felt tightness in the shoulder while long-tossing in the outfield before the game.
Young, who signed with the Mets as a free-agent in the offseason, received two anti-inflammatory injections during the week. He underwent an MRI on Sunday morning at the Hospital of Special Surgery in Manhattan to determine the extent of the injury.
Dillon Gee, who made an emergency start in place of Young on Saturday, temporarily could step into Young's spot in the rotation -- though Young’s next turn in the rotation is Thursday, which is an off-day between road series in Colorado and Houston.
Young has suffered through several shoulder injuries in recent seasons. He made just four appearances with the San Diego Padres last season because of lingering shoulder ailments related to a surgery he underwent in 2009.
Young was placed on the disabled list on April 16 with bicep tendinitis at the spot where the bicep meets the shoulder.
Young (1-0, 1.88) downplayed the severity of the injury on Saturday night.
“Last year I could barely even pick up a ball,” he said. “…. This, I can go through the motion. It’s just grabbing as I try to increase the intensity.”
The team also moved Johan Santana from the 15-day disabled list to the 60-day disabled list. That's simply a clerical maneuver that avoids Santana counting against the 40-man roster. He is still expected to get on a mound this week and return in July.
Misch, 29, spent a two-day stint with the Mets earlier this season. The lefty went 0-4 with a 3.82 ERA in 12 games (six starts) for the Mets last year.
