Wyman shot a 3-under 68 (6-under overall) to jump ahead of Cole Anderson and lead the tournament after two rounds.
"It was pretty stress free I had a couple tough par putts at the end. For the most part I was right down the middle so that helped me," Wyman said.
Bangor native Drew Powell shot a 1-under 70 (4-under overall) and will be in the final pairing tomorrow.
"We want to play against as good players as we can and Cole (Anderson) and Jack (Wyman) are certainly solid players, let's see what I can do tomorrow i'm excited," Powell said.
Anderson scuffled a bit Wednesday but ended up shooting an even par 71 (5-under overall) and is in great position to possibly take home his first Maine Amateur.
"To win the Maine Am is something that I felt like i'm definitely capable of doing and you know still feel that way and glad i've put myself in a position to do it," Anderson said.
All three will be in the final pairing tomorrow.
Other notable golfers who made the cut include Tom Caron (Bangor Municipal Golf Course), Eric Dugas (Husson men's golf), Logan Thompson (Mattanawcook Academy), and Bill Boyington (Penobscot Valley Country Club.
The final round kicks off tomorrow morning at 7:30.
