In the 141-pound bout, freshman Mike Booth faced a 1-0 deficit late in the third period before scoring a reversal and near fall.
Booth sneaked behind and on top of Spartan Corey Williams to get the eventual winning points and put UNC up
11-0 after three bouts.
Despite being down to a senior wrestler, Booth said he never thought he was going to lose.
"I was still pretty confident going into the final period," Booth said. "I've been in that position before, and I knew what I needed to do. At the end, it was actually a bonus to get the near fall, so I just went for it."
Lam said, "That's probably one of the better guys on their team and, coming in as a freshman, (Booth has) been getting a little better but hasn't put together his wins yet, so I was proud of him."
Lam gave another freshman, Jake Reynolds, a chance to win in the match's 165-pound bout.
Reynolds responded strongly in the opening periods, posting a 6-2 lead heading into the final seconds of the third until a slip-up occurred.
Spartan Nate Parmenter noticed Reynolds pulling away late and took charge. He scored a takedown and two back points to tie the score at 6-6 with two seconds remaining in regulation.
"I relaxed too much," Reynolds said. "I shouldn't have relaxed and just waited until it was all over, but he caught me.
"But I had to keep my head cool and not get upset about it, because if I did, then my wrestling would've been a lot poorer than it was at the very end."
A cooler head did help Reynolds prevail as he notched a reversal in the second sudden-death overtime session to gain a 8-6 win and push UNC's lead to 24-0.
