WINDHAM — In a dominant day for the top seeds, Keene State alum Ryan Kohler, representing Hooper Golf Club in Walpole, advanced to the semifinals of the Mid-Amateur Match Play Championship at Windham Country Club Tuesday.

Kohler, the top seed in the championship flight, faced No. 5 seed Joshua Chamberlain (Stonebridge Country Club), his partner from last week’s Spring Four Ball, in one semifinal today. In the other, No. 2 seed Harvin Groft (The Oaks) played No. 6 Matthew Walsh (Granite Fields Golf Club).

Kohler breezed to two wins Tuesday, defeating No. 16 Jimmy Lyndes and No. 9 Robert Geverd, 5-and-4. Chamberlain topped No. 12 Tyler Somers in the first round, 7-and-6, then needed 19 holes to get past No. 4 Aaron Loring.

In the Senior Championship, Bretwood’s Mike Blair earned the No. 2 seed after Monday’s medal round, but lost a 2-and-1 decision to David Kane (Derryfield CC) in his first match play round Tuesday.

Defending champion Craig Steckowych is one of the four semifinalists still alive, along with Kane, Bob Landry (Loudon CC) and Tony Fournier (Portsmouth CC).
