The shooting occurred at a popular park and baseball complex across the Potomac River in Alexandria, where Republican lawmakers and others were gathered for a morning practice about 7 a.m.
"I would say that when he arrived he was in critical condition with an imminent risk of death", Dr Jack Sava told reporters.
The doctors said that while Scalise remains in critical condition, they "are encouraged by improvement in his condition". But he will remain in the hospital for "a considerable period of time" and faces additional operations.
A single rifle wound caused "substantial damage" to Scalise's internal organs and blood loss, his doctor explained Friday.
"I feel a lot more confident and a lot more optimistic than I did two, three days ago", Sava said.
Sava said Friday that there are hundreds of bullet fragments in Scalise's body, but "we have no intention to try and remove all the bullet fragments at this point". Griner was in good condition "and in good spirits", Sava said.
In a final flourish of bipartisan camaraderie for the night, Democratic Rep. Mike Doyle of Pennsylvania, his team's manager, accepted the trophy, then gave it to his GOP counterpart, Rep. Joe Barton of Texas, to put in Scalise's office on behalf of the Democrats.
"By playing tonight you are showing the world that we will not be intimidated by threats, acts of violence, or assaults", Trump said.

Scalise's wife, Jennifer, issued a statement saying she was thankful for the "incredible amount of prayers and warm wishes" the family has received since the shooting.
Scalise was an enthusiastic participant in the ballgame - in 2015 he posted pictures from the many times he played in the competition against the Democrats' team.
I would also like to personally thank all of the first responders who bravely assisted at the scene, as well as the entire staff of MedStar Washington Hospital Center for their continued excellent care.
The president said that because of the "tremendous pain and suffering he's now enduring. our country will perhaps become closer, more unified".
Trump added that Scalise is "having a hard time, far worse than anybody thought" following the shooting Wednesday. Some people carried with them Scalise signs to support the injured congressman.
Scalise is said to be somewhat responding to medical staff and family, according to the doctors.
In his speech in Miami Friday, President Trump called for unity in the aftermath of Wednesday's shooting at a GOP baseball practice.
The game will now benefit the US Capitol Police Memorial Fund after two officers injured protecting members of Congress Wednesday, in addition to other charities.
The players planned to wear some Louisiana State University gear in honor of Scalise, a graduate of the school.
