Reed, the home-plate umpire on Wednesday, accused the Angels' coaching staff of verbally abusing the umpiring crew as it was leaving the field, according to the Boston Herald.
Reed, who issued a game-tying walk to pinch-hitter Nick Green in the bottom of the ninth on a 3-2 pitch from Brian Fuentes that the Angels were convinced was a game-ending strike three, said that a report and complaint had been sent to American League officials by the umpires.
Umpires at Fenway Park leave the field through the visitors' dugout tunnel, putting them in close contact with coaches and Scioscia, who felt the Angels had a game taken from them by calls favoring the Red Sox.
"Their deportment as we left the field, going through the Angels' dugout, left a lot to be desired," Reed told the Herald before Thursday night's series finale. "I will say this: I'm disappointed in the coaches. Coaches are usually the guys who try to stop any kind of friction that develops in the course of a game and afterward, but they were initiating last night, and I'm not pleased in the way they said things or in their presentation. I think Major League Baseball has been notified, and probably something will become of it, I don't know what."
Angels coaches had words with the umpiring crew before Scioscia intervened, according to Reed, whose praise for the manager was sparing.
"Mike made an attempt to quiet his coaches down," Reed said, "but he also made a comment that I thought incited the situation."
Scioscia, who said that the Angels also spoke with league officials, again flatly denied the accusation.
"What happened in the walkway is, we had a very emotional club upset with the way the game ended," he said. "We stopped -- kept everybody back -- to give them a buffer zone to get up.
"I made a quiet comment to Rick Reed. That's between him and me. If anything was instigated, it was [umpire] Mike Wegner coming back and confronting one of our coaches. If anything, it was a little lessening in professionalism by Mike Wegner that needs to be discussed."
Wegner was working at third base on Wednesday.
Referring to the behavior of the Angels coaches, Reed said it was "unprofessional and unbecoming of a professional team, that's how bad it was.
"We filed a report after the game, and I would think there will be a coach or two over there that would be regretting his actions today."
Pitching coach Mike Butcher appeared baffled by Reed's comments.
"I really don't know anything about that," Butcher said. "I was on the field while they were leaving."
As for the 3-2 pitch to Green that the Angels contended was clearly in the strike zone, Reed said that upon further review, "It very well could have been a strike. It was a pitch in the bottom of the strike zone."
Reed added that catcher Mike Napoli moved his glove up after he caught the pitch, which Reed interpreted as meaning that the ball was low.
