The health of New York Mets right-hander Jacob deGrom's newborn son has improved, according to manager Terry Collins.

The Mets placed deGrom on family emergency leave Saturday because of health "complications" with Jaxon Anthony, who was born Monday night.

"Last night I talked to him," Collins said Sunday morning. "The baby is doing better. That was a good sign. I just told Jake he needs to get some rest and mix in a meal."

Collins said deGrom appears exhausted, "mentally more than physically."

DeGrom will be inactive for three to seven days, but he is continuing to throw off a mound during his absence from the team. He was in the process of throwing a 40-pitch bullpen session Sunday morning at the team's Florida complex after commuting 2½ hours from his family's home in DeLand.

Team officials believe deGrom could re-enter the rotation for an abbreviated outing as soon as next weekend in Atlanta if his family situation allow
