Austin Jenner of West Branch advanced to the "Sweet 16" round at the 104th Michigan Amateur after downing Reed Hrynewich of Muskegon Wednesday.
Jenner, 17, who is a student at Skeels Christian School in Gladwin, made seven putts over 12-feet in length, including a 35-footer on hole No. 1 in charging to a 2 and 1 win over Hrynewich in the second round of matches at Plum Hollow Country Club.
Jenner, who outlasted 44-year-old David Hall of Birmingham in 19 holes in his morning round of 32 match before knocking off Hrynewich, will play Oakland Community College golfer Justin Pahl of White Lake in the round of 16.
The championship includes two more rounds of match play on Thursday to determine a final four. Semifinal and final matches are Friday.
Henry Do, a University of North Carolina golfer, started match play defense of his title with wins over Austin Carter of Port Sanilac (2-up) and Evan Bowser of Dearborn (4 and 3).
Tom Werkmeister of Kentwood, the 2014 Golf Association of Michigan Player of the Year, topped Brad Bastion, the 2013 GAM Player of the Year, 1-up in their afternoon match. Werkmeister, a regular in the Sweet 16, will play another Kentwood area golfer, Brett White, who plays college golf at Eastern Michigan.
Ryan Johnson of New Boston topped 2013 GAM Champion Scott Strickland of Birmingham 4 and 3 in another key afternoon match after beating Ryan Mouw of Muskegon 3 and 2 in the morning. Johnson has made the Sweet 16 three consecutive years.
